A mechanical bearing is a component used between two parts that allows rotational or liner movement, reducing friction and enhancing performance to save energy.
Both metal and plastic bearings can be found everywhere, from refrigerators to computers to the 100 or so bearings found in your car. The concept behind them is a simple one: things roll better than they slide. Without bearings, the wheels in your car would rattle, the transmission gear teeth wouldn’t be able to mesh, and the car wouldn't run smoothly. They are composed of a smooth inner and outer metal surface for metal balls to roll against. The balls or rollers help “bear” the load and the device functions more efficiently.
There are many different types of bearings, each used for specific purposes and designed to carry specific types of loads, radial or thrust. Here, we’ll look at the 6 most popular types: plain bearings, rolling element bearings, jewel bearings, fluid bearings, magnetic bearings, and flexure bearings. 

Plain bearings are the simplest type of bearing and are composed of just the bearing surface with no rolling elements. They have a high load-carrying capacity, are generally the least expensive and, depending on the materials, have much longer lives than other types.

Rolling element bearings place balls or rollers between two rings - or “races” - that allows motion with little rolling resistance and sliding. These bearings include ball bearings and roller bearings.
Ball bearings are the most common type of rolling element bearing.
These bearings can handle both radial and thrust loads but are usually used where the load is relatively small. Because of its structure, there is not a lot of contact with the balls on the inner and outer races.  If the bearing is overloaded the balls would deform and ruin the bearing. Roller bearings are able to handle a much heavier, radial load, like conveyor belts, because they don’t use balls. Instead, they have cylinders allowing more contact between the races, spreading the load out over a larger area. However this type of bearing is not designed to handle much thrust loading.

Jewel bearings are plain bearings with a metal spindle that turns in a jewel-lined pivot hole. They carry loads by rolling the axle slightly off-center and are usually used in mechanical watches or clocks. This is due to their low and predictable friction that improves watch accuracy.

Fluid bearings support their load using a thin layer of gas or liquid and can be classified into two types: fluid-dynamic bearings and hydrostatic bearings. Fluid-dynamic bearings use rotation to form the liquid into a lubricating wedge against the inner surface. In hydrostatic bearings, the fluids - usually oil, water, or air - rely on an external pump.
Fluid bearings are used in high load, high speed or high precision applications that ordinary ball bearings either couldn’t handle or would suffer from increased vibration and noise.

Magnetic bearings
support moving parts without physical contact, instead relying on magnetic fields to carry the loads. They require continuous power input to keep the load stable, thus requiring a back-up bearing in the case of power or control system failure.
Magnetic bearings have very low and predictable friction and the ability to run without lubrication or in a vacuum. They are increasingly used in industrial machines like turbines, motors, and generators.

A typical flexure bearing is one part joining two others, like a hinge, in which motion is supported by a load element that bends. These bearings require repeated bending, so material selection is key. Some materials fail after repeated bending, even at low loads, but with the right materials and bearing design the flexure bearing can have an indefinite life. Another notable characteristic of this bearing is its resistance to fatigue. Many other bearings that rely on balls or rollers can fatigue as the rolling elements flatten against each other.


Here you have it!  Did we miss a type of bearing that you prefer?  Have more questions about specific kinds of bearings?  Let us know in the comments section below.
In addition to reducing friction (and consequently wear) to almost the absolute minimum, the ball bearing has certain general advantages.  These are: —


  • POWER SAVING – With the truest rolling motion of any type of bearing, ball bearings reduce friction appreciably over roller bearings, and even more over plain bearing, under ideal or laboratory conditions.  Actually, the saving in power consumption, depends upon a number of factors in the installation, but, other things being equal, will be greater with ball bearings.

  • LUBRICATION AND LABOR SAVING – Constant oiling of plain bearings is expensive and troublesome.  Both in the cost of lubricant and in maintenance labor (due to less frequent replenishment), ball bearings can effect great economy.

  • RELIABILITY – By virtue of their practically frictionless non wearing operation, ball bearings eliminate the expensive and time-consuming rebabbitting and replacing of plain bearings.  No adjustment, repair or attention is necessary other than periodical lubrication.

  • CLEANLINESS –  Particularly with ball bearing power transmission units,where grease is used as the lubricant rather than oil, is leakage eliminated.

  • REDUCED FIRE HAZARDS – Running cool and clean, ball bearings can eliminate the fire hazard from the conditions presented by overheated and oily plain bearings.
  • INCREASED PRODUCTION – The savings in power resulting from the use of ball bearings have often permitted the use of higher speeds, smaller motors or additional equipment, without other changes being necessary.

  • INCREASED LIFE OF ASSICIATED EQUIPMENT – By eliminating the initial starting strain which is present in plain bearings after idleness, such equipment as motors and belts is relieved of the starting torques which materially shorten life.  Shaft life is likewise indefinitely prolonged, as the constant rubbing friction is eliminated.  In fact, nearly all the parts directly associated with ball bearing installations benefit from their use.

When you think about what makes the modern world tick, you might think of electricity, cell phones, airplanes, or any number of modern conveniences. What we don’t normally think of, however, is the humble bearing that makes at least two out of three of those function.
Without bearings, the wheels on your car wouldn’t roll and the engine definitely would not work. Bearings reduce friction and keep components precisely in place. These little guys are so important that the Allies decided to strategically attack German bearing capabilities during World War II, at a very heavy loss. Hopefully the bearings in your projects will be used for more peaceful purposes.


Types of Loads

I suppose you could say that all three can withstand force in either direction, since a lazy susan doesn’t slide horizontally across a table and skateboard bearings don’t just slide off their axes. However, the main force resisted is decidedly in one direction.




There are many specialized types of bearings. Here are a few you might see in your everyday life while making awesome stuff:
  • Normal” Radial Ball Bearing – What someone would normally think of as a bearing, with two concentric metal circles separated by little metal balls. These simple bearings can be found in everything from skateboards to drills.
  • Pillow Block BearingThese bearings are a radial load bearing encased in a housing that can be attached to a surface parallel to the axis of rotation.
  • Cam Follower Bearing A radial load bearing with a threaded rod attached to it. Generally meant to ride on a cam to cause linear motion, these could have other interesting applications.
  • Ball Bushing (Linear) Bearing This type of bearing is used extensively to allow for the smooth motion of 3D printer and CNC router heads. Their purpose, unlike the other bearings here, is to restrict radial motion, while allowing smooth linear motion.
  • Automotive Wheel Bearing These are generally taperer roller bearings, allowing for both radial and axial load to be overcome.
  • Thrust Bearings These have many uses (especially automotive), but lazy susans and bar stools are what immediately come to mind as easy examples of their use. They could also be useful for anything else that needs to rotate smoothly, like a camera panning device.
Alternatives
If you’re able to use bearings in your design, that is really good. However, in most applications this does take planning and extra expense. If you’re in a hurry, or are short on space, you might instead consider using a low friction material in your design. I’ve used Teflon washers successfully in a project at home. If you have access to it, there are also many low-friction coatings available.
That being said, if you can afford (both in terms of patience and money) to use bearings, it is really great to see a well engineered project that uses bearings to keep things in line and moving smoothly.

There are several types of bearings, and each has its own interesting uses, including magnetic bearings and giant roller bearings.

Magnetic Bearings



Some very high-speed devices, like advanced flywheel energy storage systems, use magnet bearings. These bearings allow the flywheel to float on a magnetic field created by the bearing.

Some of the flywheels run at speeds in excess of 50,000 revolutions per minute (rpm). Normal bearings with rollers or balls would melt down or explode at these speeds. The magnetic bearing has no moving parts, so it can handle these incredible speeds.

Giant Roller Bearings

Probably the first use of a bearing was back when the Egyptians were building the pyramids. They put round logs under the heavy stones so that they could roll them to the building site.
This method is still used today when large, very heavy objects like the Cape Hatteras lighthouse need to be moved.

Earthquake-Proof Buildings


The new San Francisco International Airport uses many advanced building technologies to help it withstand earthquakes. One of these technologies involves giant ball bearings.


The 267 columns that support the weight of the airport each ride on a 5-foot-diameter (1.5-meter) steel ball bearing. The ball rests in a concave base that is connected to the ground. In the event of an earthquake, the ground can move 20 inches (51 cm) in any direction. The columns that rest on the balls move somewhat less than this as they roll around in their bases, which helps isolate the building from the motion of the ground. When the earthquake is over, gravity pulls the columns back to the center of their bases.

Deep Grove Ball Bearing

Product Specification

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
MBP use improved ball quality to so to provide noise free bearings and smooth running 
MBP ball bearings have an optimized surface finish on all the contact surfaces to provide the sufficient  lubrications this allows the bearings to run cooler and last longer

Spherical Roller Bearing

Product Specification

A spherical bearing is a bearing that permits angular rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry). Typically these bearings support a rotating shaft in the [bore] of the inner ring that must move not only rotationally, but also at an angle.
Spherical bearings can be of a hydrostatic or mechanical construction. A spherical bearing by itself consists of an outer ring and an inner ring and a locking feature that makes the inner ring captive within the outer ring in the axial direction only. The outer surface of the inner ring and the inner surface of the outer ring are spherical and are collectively considered the raceway and they slide against each other, either with a lubricant, a maintenance-free or they incorporate a rolling element such as a race of ball-bearings, allowing lower friction. Spherical bearings are used in countless applications, wherever rotational motion must be allowed to change the alignment of its rotation axis.

Cylindrical Roller Bearing
Product Specification


Cylindrical roller bearings offer excellent resistance to instantaneous overloads and shocks.
They simplify assembly thanks to their detachable elements and allow, for certain types, axial displacement or low axial load, for other types.
Cages
The standard cage for these bearings is the polyamide cage which allows bearing operating temperatures of 120°C or 248°F (150° or 302°F peak). The standard cage for series 4 is in pressed steel. The machined brass cage is available on option. Large-dimension bearings are equipped with a machined brass cage. For special applications in which the synthetic material cage is unacceptable, a metal cage can be provided on request.
Capabilities
Loads and speeds
  • Withstand radial loads
  • Withstand moderate axial loads if the position of the shoulders on the rings allows them accept high speeds of rotation
Misalignment
Cylindrical roller bearings accept misalignment of about 0.06° thanks to the correction on the roller surface profile

Taper Roller Bearing
Product Specification

The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing
This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e. the differences in surface speeds creates a scrubbing action. Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems. Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear.
The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
The larger the half angles of these cones the larger the axial force that the bearing can sustain.
Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup. Internal clearance is established during mounting by the axial position of the cone relative to the cup.
