调心滚子轴承具有双列滚子，外圈有1条共用球面滚道，内圈有2条滚道 并相

Aligning roller bearing has double rows of rollers, the outer ring has a common spherical raceway, the inner race has two raceways and inclined relative to the bearing axis at an angle. This ingenious construction so that it has a self-aligning property, and thus less susceptible to the shaft and bearing box or shaft seat angle bending error, or for installation errors caused by shaft deflection angle error of occasions. The bearings in addition to radial loads, but also axial load double acting.

The centered roller bearing has a double-row roller, the outer ring has a common spherical raceway, the inner ring has 2 raceways and is tilted to an angle relative to the bearing shaft. This clever construction makes it automatically adjustable and therefore not susceptible to the influence of shaft and bearing seat angle on error or shaft bending, and is suitable for installation error or shaft deflection and causing angle error. In addition to being able to withstand radial loads, the bearings can also withstand axial loads for two-way use.

The self-aligning roller bearing has double row rollers, the outer ring has one common spherical raceway, and the inner ring has two raceways and is inclined to an angle with respect to the bearing axis. This ingenious structure makes it have the function of self-aligning, so it is not easy to be influenced by the angle between the shaft and the bearing housing on the error or the bending of the shaft. It is suitable for the occasion where the angle error is caused by the installation error or the bending of the shaft. The bearing can bear not only the radial load, but also the axial load of two-way action.<br>
