6900 Series Deep Groove Ball Bearings

Special feature of this series

Main dimensions according to DIN 625-1. Thin section bearings of the 69 series have considerably smaller dimensions than deep groove ball bearings of the 60, 62, 63, and 64 series with their thin, square cross-section at the same inside diameter. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They are extremely light and are suitable for comparatively high speeds.

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.

Manufacturers of bearings: such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Can be customized to meet your specific needs.
