Spherical roller bearing inner ring with 22212 ribs.
Spherical Roller BearingsSpherical roller bearing is composed of a spherical raceway outer ring and a double raceway inner ring, one or two holders and a group of spherical roller. Because the center of the outer spherical raceway is consistent with the center of the bearing, it is self-aligning, and can automatically adjust the inclination or deflection of the shaft due to the angular error between the shaft and the bearing housing.Structure and characteristicsSpherical roller bearings are divided into: cylindrical hole, tapered bore.Hole taper cone respectively of 1:12 rear code for K spherical roller bearing and the rear code for K30 spherical roller bearing 1:30. The inner hole is tapered bore bearings can be installed directly on the axis of the cone, the bearing shaft with a conical distribution, inner ring along the axial movement of the bearing can adjust radial clearance; or use the sleeve, remove the sleeve installed in the cylinder axis.

There are two types of C and CA types, depending on the inner ring, the retaining edge and the cage used.C type bearing inner ring without edge, use steel plate holder.Both sides of inner ring of type CA bearing are blocked with car body cage.For convenience and ease of lubrication, spherical roller bearing with lubrication holes and lubrication groove,The outer ring is provided with a lubrication groove and three lubricating holes. The rear code name is W33.Spherical roller bearings can bear large radial load and bi-directional axial load. Especially suitable for heavy load or impact vibration load. But allow the working speed of roller bearings is relatively low.
