Spherical roller bearings are equipped with double row rollers, with a shared spherical raceway on the outer ring and two raceways on the inner ring, forming an inclined angle with respect to the bearing axis. The unique structure has its own automatic centering feature, which is less affected by the assembly angle deviation between the shaft and the bearing housing and the shaft bending, and can adapt to the use scenario of angle deviation caused by installation deviation and shaft deflection. This bearing can bear radial loads and can also withstand bidirectional axial loads.

The inner holes of self-aligning roller bearings are divided into two types: cylindrical and conical. The conical inner hole includes two types of taper: 1:30 and 1:12; Bearings with tapered inner holes can be easily and quickly assembled onto the optical axis or stepped machine shaft with a tightening sleeve or a retraction sleeve.

Spherical roller bearings are mainly divided into six types:

Self aligning roller bearing (20000CC type)

Conical hole self-aligning roller bearing (20000CCK type)

Self aligning roller bearing (20000CC/W33 type)

Conical hole self-aligning roller bearing (20000CCK/W33 type)

Matching tight fitting sleeve self-aligning roller bearing (20000CCK+H type)

Matching tight fitting self-aligning roller bearings (20000CCK/W33+H type)
