Understanding The Importance and Advantages of Ball Bearing Rollers

Ball Bearing Rollers

Bearings are the smallest elements of the machine that are responsible for making various motions possible without friction. The different motions are possible in the machine due to these bearings that include circular, linear, etc. The different variations in the rolling elements include balls, spheres, cylinders, tapered cylinders, needles, etc.

Variants of ball bearing rollers:

There are different types of rolling elements available but the most common and the basic rolling element is the ball roller. These are different types of bearings that incorporate these balls as the rolling elements and these include:

Deep-groove bearings: These are the commonly used bearings that have the inner and the outer raceways having a circular arc that accommodate these balls. These bearings can accommodate the axial as well as radial loads in both directions. As these bearings have low torque, they attain higher seed with very little power loss.

Magneto bearings: The inner raceways are shallower as compared to the outer ones so these two can be separated. This helps in the easy mounting of the bearings.

Single-row angular contact bearing: The ball bearings in these make a specific angle of contact that varies from 15, 25, 30, and 45. Higher the contact angle, higher load-carrying capacity is attained. For high speed of motion, a smaller contact angle is preferred. For increasing the efficiency of these bearings, they are used in pairs.

Duplex angular bearings: In these bearings, the single-row bearings are used in pairs. The arrangement of these rows while coupling defines the different types of bearings like back-to-back (DB type), face-to-face (DF types), and tandem (DT type).DF and DT variants are useful while handling the axial and radial loads in either direction. DT type of bearings is preferred when handling heavy loads in a single direction.

Four-point contact bearing: The inner raceway has a slit in its radial plate that helps in separating the outer and the inner ring. The contact angle in these bearings is 35 degrees and it holds the axial load in either direction.

Thrust bearing: The ball holding rings are washer-like. These bearings may include 2 or more rings. These modifications help in accommodating the loads in a single or double direction.

Self-aligning bearing: The inner ring incorporated 2 raceways as compared to only one raceway in the outer ring. This setting allows to automatically correcting the errors that arise due to minor misalignment between the shaft and housing.

Considering the simplicity and the various advantages of using these ball bearing rollers, these are the most convenient choice of bearings. Selection of the proper type of bearing is important for its efficient working.
