What is the Double Row Self Aligning Ball Bearings?

Double row self aligning ball bearings mainly bear radial load, but also can bear a small axial load, generally do not bear pure axial load. The bearings are mainly double row bearings, there are two rows of steel balls, inner ring has two raceways, outer ring raceway for the inner spherical shape, so it has the performance of self-aligning, can automatically compensate for the shaft deflection and shell deformation coaxial error, suitable for the support seat hole can not ensure strict coaxiality of the parts, but the relative tilt of the inner and outer ring can not exceed 3. Its limit speed is lower than the single row deep groove ball bearings can not be split, commonly used There are pressed cage and nylon cage. These bearings are mainly used in combine harvesters and other agricultural machinery, blowers, paper machines, textile machinery, woodworking machinery, bridge cranes and drive shafts.

The main structure type are:

1. cylindrical hole double row self aligning ball bearings 10000 type.

2. Tapered hole (taper 1:12) double row self aligning ball bearings 10000K type.

3. Double row self aligning ball bearings 10000K+H type mounted on the tightening sleeve. The taper of the inner ring of the bearing is also 1:12, the outer circle of the sleeve has the same taper as the bearing hole, the inner hole of the sleeve is cylindrical, the small end of the sleeve has threads, and is equipped with nuts and stop washers. This kind of bearing is suitable for mounting on the light shaft without shoulder, easy to install and disassemble. With the tightening sleeve can also adjust the radial clearance of the bearing, to obtain the appropriate clearance, with a stop washer to fix the position of the bearing on the shaft down.
