2320 Self aligning ball bearing

Self-aligning ball bearing outer ring raceway is processed into spherical shape, inner ring has two deep groove raceway double row ball bearing, self-aligning properties. It is mainly used to bear radial load, the bear radial load at the same time, also can take a small amount of axial load, but usually can't bear to pure axial load, its limit rotational speed is low deep groove ball bearings. These bearings used in more easily bent double under the action of a load on the supporting shaft, and the double socket hole cannot ensure strict alignment components, but the relative slope of the center line of the center line of the inner ring and outer ring shall not exceed 3 degrees.

Self-aligning ball bearing basic types

12, 13, 22 and 23 series of self-aligning ball bearing inner hole can be cylindrical or conical. Bearings with inner hole taper 1:12 (code suffix K) of the self-aligning ball bearing can be directly mounted to the conical shaft, can also be through a set of installation set to cylindrical shaft,  addition to providing self-aligning ball bearing without seal, also can provide with sealing cover on both ends of the basic types of self-aligning ball bearing (2 rs code suffix).

Self-aligning ball bearing clearance of the bearing

The basic types of cylindrical hole self-aligning ball bearing manufacturing clearance to normal group, the radial clearance is bigger than normal group bearing (code suffix C3) on request for. Self-aligning ball bearing the basic types of taper hole of the radial clearance is bigger than normal group of C3 group.

Self-aligning ball bearing seal

Sealing self-aligning ball bearing (code suffix. 2 rs) on both ends with sealing cover (contact seal). In order to ensure life, they have joined the grease in the factory. Sealed bearing - 30 ℃ is the minimum operating temperature limit.

In a self-aligning ball bearing

Self-aligning ball bearings allow the shaft bearing center around 4 ° deflection, seal self-aligning ball bearing can compensate the biggest 1.5 °.
