Self-aligning ball bearings usually have two kinds of structure, cylindrical bore and conical bore, retainers’ material always with armor plate, synthetic resin and so on. The features of such bearings are as following, its outside rollaway nest is in shape of sphere, together with the function of self-aligning, therefore, it can complete the error caused by eccentricity and axle deflection curve, but the relative gradient between inside track and outside track should not excess 3 degree.

Adjustment to angle and standard error. Meanwhile, such bearings also have the design of seal and no need of lubrication can be used in the working condition of no maintenance. As to the adapter sleeve and SKF pillow bearing block on the self-aligning ball bearings, we can offer our clients economic bearing collocation. 2.1 Cylindrical bore self-aligning ball bearings (10000 series) 2.2 Conical bore self-aligning ball bearings (10000K series) 2.3 Self-aligning ball bearing with adapter sleeve (10000K+H10000 series).

The structure of self-aligning ball bearings include: with dust cup and with seal ring, these two kinds. While during assembling, appropriate amount of lubricating grease already been filled in the bearing, there’s no need to heat up or cleanout bearing before installing, nor need to lubricate any more, meanwhile, it’s suitable to work from the temperature from -30℃ to +120℃. Because of such kind of bearings all with two double row grounders and the rollaway nest of cambered surface in outside track, self-aligning ball bearings can self centering, and endure the angle error between axes and bearing block, so that can be used during such working condition of axes flexure and misalignment which appear easily. The cylindrical bore and conical bore these two structures are usually with the retainer of the material of armor plate, synthetic resin and so on. The attrition of self-aligning ball bearings is the lowest among all the roll bearings, so it just have very small temperature rise even during the condition of high rotation speed.
