Stainless Steel Deep Groove Ball Bearing SS 6904 / 61904 C3 ZZ / 2Z 20x37x9 mm
Item number: SS-6904-ZZ-C3
Narrow, light and with very good spinning characteristics. The stainless steel deep groove ball bearing SS-6904-ZZ / 2Z-C3 is narrow, can also be used with limited space and is resistant to corrosion. The low weight allows for very high speeds.

- all components are made of stainless steel: the deep groove ball bearing has therefore good corrosion resistance to mild media (e.g. fresh water) and is hygienic
- thin section bearing with a thin cross section
- suitable for space-saving installation in radial and axial directions
- suitable for high speeds compared to deep groove ball bearings with a larger cross section
- extra light series with compact dimensions and low weight
- suitable for radial loads and light axial loads in both directions
- offers high running accuracy and very high speeds
- seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
- with increased radial internal clearance (C3): for high temperature gradient between the bearing rings or for fastening with press fit
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
- 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)
