Self-aligning ball bearings — Variable shaft guidance

Self-aligning ball bearings have the same basic characteristics as deep groove ball bearings. However, they have two rows of balls. These can be pivoted together with the inner ring by a few degrees. Thus, the bearing can compensate for misalignment and deflections of the shaft.

Versions of self-aligning ball bearings

Self-aligning ball bearing
Main dimensions according to DIN 630. Double row. Usable in case of high radial and low axial load-ratings. Excellent compensation of misalignment. With cylindrical or tapered bore.
With extended inner ring
Main dimensions according to DIN 630. For the simple and stable fixing onto a shaft through a shoulder screw.

Material description of self-aligning ball bearings

Self-aligning ball bearings made of rolling bearing steel
are cost-effective and can withstand very high loads. The bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
Self-aligning ball bearings made of stainless steel
are hygienic, corrosion-resistant (to fresh water), sometimes lubricated with food-grade grease (recognizable by the suffix -GF), magnetic and withstand high loads.
