Self-aligning ball bearings

 

Self-aligning ball bearings from the outside:

The self-aligning ball bearing has two rows of steel balls, two raceways in the inner ring, and the raceway in the outer ring is spherical type, which has the performance of self-alignment. It can automatically compensate for the coaxiality error caused by the deflection of the shaft and the deformation of the shell, and is suitable for parts where the coaxiality cannot be guaranteed by the support seat hole. This kind of bearing mainly bears radial load, while bearing radial load, it can also bear a small amount of axial load, usually not used to bear pure axial load, such as bearing pure axial load, only a row of steel balls are stressed

 

Spherical roller bearings have two rows of rollers, which are mainly used to accommodate radial loads, but also axial loads in either direction. This kind of bearing has a high radial load capacity, especially suitable for working under heavy load or vibration load, but can not bear pure axial load; The self-alignment performance is good, and the coaxiality error can be compensated.

 

The inner bore of the spherical roller bearing has two kinds of cylindrical and conical, the taper of the conical bore is 1:30 and 1:12, and the conical bore bearing is equipped with an adapter sleeve or a withdrawal sleeve, and the tapered bore self-aligning ball bearing can be conveniently and quickly assembled on the smooth shaft or the ladder machine shaft.

 

Spherical roller bearings have double rows of rollers, with one shared spherical raceway in the outer ring and two raceways in the inner ring that are inclined at an angle to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not susceptible to the influence of the angle of the shaft and the bearing housing on the error or shaft bending, and is suitable for the occasion of angular error caused by installation error or shaft deflection. In addition to radial loads, the bearing can also withstand axial loads that act in both directions.

 

The inner bore of the spherical roller bearing has two kinds of cylindrical and conical, the taper of the conical bore is 1:30 and 1:12, and the conical bore bearing is equipped with an adapter sleeve or a withdrawal sleeve, and the tapered bore self-aligning ball bearing can be conveniently and quickly assembled on the smooth shaft or the ladder machine shaft.

 

The models of spherical roller bearings are: spherical roller bearings (20000CC type); Tapered bore spherical roller shaft bearing (20000CCK type); Spherical roller bearings (20000CC/W33); Tapered bore spherical roller bearings (20000CCK/W33); Spherical roller bearings mounted on adapter sleeves (20000CCK+H type); There are 6 types of spherical roller bearings (20000CCK/W33+H type) mounted on adapter sleeves.
