Double Row Angular Ball Bearings of the Series 52 / 32

Special feature of this series
Main dimensions according to DIN 628-3. In comparison to single-row angular ball bearings with the same inner and outer diameter, double-row angular ball bearings of the series 52 / 32 are wider, but on the other hand considerably more resilient.
Seals
Rubber seals (RS/2RS) have the optimum sealing action with increased friction. Metal seals (Z/ZZ) are suitable for higher speeds, but they have a limited sealing action as they seal contactless. Open, seal-less bearings are suitable for extremely high speeds and - furthermore - they can be regreased more easily. However, they are more susceptible to soiling. | more
