Bearings, their types and application

Bearings, their types and application

   A bearing is a device that is used to enable rotational or linear movement, while reducing friction and handling stress. Resembling wheels, bearings literally enable devices to roll, which reduces the friction between the surface of the bearing and the surface it’s rolling over. It’s significantly easier to move, both in a rotary or linear fashion, when friction is reduced this also enhances speed and efficiency. Types of Bearings: Different application require bearings that are designed to handle a specific type of load, normally bearings are designed to handle Radial or Thrust load or a combination of two. A radial load, as in a pulley, simply puts weight on the bearing in a manner that causes the bearing to roll or rotate as a result of tension.

Ball bearings are extremely common because they can handle both radial and thrust loads, but can only handle a small amount of weight. They are found in a wide array of applications, such as roller blades and even cycles, but are prone to deforming if they are overloaded.· Tapered roller bearings · Roller thrust bearings · Ball thrust bearings · Roller bearings· Ball bearings ·Thrust loads are force that is applied parallel to the bearing's axis. They are also called axial or linear loads. Depending upon applications described above, bearing can be divided into following types, the differences between types of bearings concern load type and ability to handle weight.

 

2, Roller Bearing

 Roller bearings are designed to carry heavy loads the primary roller is a cylinder, which means the load is distributed over a larger area, enabling the bearing to handle larger amounts of weight. This structure, however, means the bearing can handle primarily radial loads, but is not suited to thrust loads. For applications where space is an issue, a needle bearing can be used. Needle bearings work with small diameter cylinders, so they are easier to fit in smaller applications. Roller Bearing Roller bearing in gear box

 

3,Ball Thrust Bearing

These kinds of bearings are designed to handle almost exclusively thrust loads in low-speed low-weight applications. Bar stools, for example, make use of ball thrust bearings to support the seat.

The difference, however, lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical
