A bearing is the device which is used to enable rotational and linear movements, which helps to reduce friction and handling stress. Bearing helps the devices to roll, which reduces friction between the surface of the bearing and the surface of the devices. Many bearings are prone to experience both radical and thrust loads. There are various types of bearing which are used to handle the radial load, thrust load, or some combination of the two. Some of them are listed below:
Ball bearing are the most common because they support both radial and thrust loads, but handle only small amount of weight. These bearings are available in wide array of applications, such as roller blades and even hard drives, but they face down to deform if overloaded. You can also buy ball bearings for replacing the roller blades in the ceiling or stand fans.
Roller bearings are designed to carry heavy loads. The primary roller is a cylinder which means the load is distributed among the larger surface area, which helps the bearing to hold larger weights. This helps the bearing to primarily radial loads, but is not appropriate for the trusted loads. For applications where space is an issue a needle bearing can be used. These needle bearing work with small diameter cylinders so that they are easier to fit and work in smaller applications.
Ball thrust bearing:
These bearings are designed to use for the low-speed low-weight applications. For example, the bar stools are made using these bearings, which helps to support the seat.
Roller thrust bearing:
Much like ball thrust bearing roller thrust bearings handle trust loads, the only difference between them the amount of weight a handle can handle. Roller thrust bearings can support significantly larger amount of thrust loads, especially found in car transmissions which helps to support the helical gears. Gear support is the common application of the roller thrust bearing.
Tapered roller bearing:
This is designed to handle large radial and thrust loads which helps in load versatility. They are available in car hubs due to extreme amount of both radial and thrust loads, which helps to carry the car wheels.
There are various bearing available that are manufactured for specific applications. For example- magnetic bearings and giant roller bearings. Magnetic bearings are generally used in the high speed vehicles which doesn’t have any moving parts. This helps to support the devices more which run awfully fast. At the same time, giant rollers are used to move extremely large and heavy loads such as large buildings or large structural components.
These are some of the best types of bearings which are available, choose the best which you are in need of.
