Overview of Roller Bearing Types

- Oct 17, 2019-

1.Roller bearing

It’s a rolling bearing that the rolling body is roller.

2. Radial roller bearings

 It’s a radial rolling bearing that the rolling body is roller.

3. Cylindrical roller bearing

It’s a radial rolling bearing that the rolling element is Cylindrical roller.

4. Tapered roller bearing

 It’s a radial rolling bearing that the rolling element is tapered roller.

5. Needle roller bearing

It’s a radial rolling bearing that the rolling element is Needle roller.

 6. Drawn cup needle roller bearing

Sheet metal stamping (stretching) outer ring radial needle roller bearings, one end closed or open at both ends, often without inner ring.

7. convex roller bearing

It’s a radial rolling bearing that the rolling element is convex roller.

8. Concave roller bearing

It’s a radial rolling bearing that the rolling element is Concave roller.

9. Spherical roller bearing

The rolling element is a self-aligning radial bearing with a convex spherical surface or a concave roller. A bearing having a convex spherical roller has a spherical raceway on the outer ring; a bearing having a concave roller has a spherical raceway on the inner ring.

10. Crossed roller bearing

An angular contact rolling bearing with a row of rollers, the adjacent rollers intersecting in a cross configuration such that half of the rollers (each second roller) are subjected to axial load in one direction, while the axial load in the opposite direction is carried by the other half The roller bears.

11. Thrust roller bearing

 It’s thrust rolling bearing that the rolling body is roller.

12. cylindrical roller thrust bearing

 It’s thrust rolling bearing that the rolling body is cylindrical roller.

13.  tapered roller thrust bearing

It’s thrust rolling bearing that the rolling body is tapered roller.

14. needle roller thrust bearing

 It’s thrust rolling bearing that the rolling body is needle roller.

15.  spherical roller thrust bearing

It’s self-aligning thrust rolling bearing that the rolling body is convex spherical surface or concave roller. The raceway of the bearing race with the convex spherical roller has a spherical shape, and the raceway of the concave spherical roller bearing has a spherical shape.
