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 economical, withstand extremely high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals and metal cage temperature-resistant up to circa +100°C in the long run, in case of the use of polyamide cages usable up to circa +70°C. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
Self-aligning ball bearings made of stainless steel: are hygienic, corrosion-resistant, lubricated with grease for the food industry, magnetic and admissible for a temperature range from circa -20°C up to +120°C. With rubber seals and metal cage temperature-resistant up to circa 100°C in the long run, in case of the use of polyamide cages usable up to circa +70°C.
