Stainless Steel Miniature Deep Groove Ball Bearing Inch SS2 R2 ZZ / 2Z 3.175 x 9.525 x 3.967 mm
Item number:
SS2-R2-ZZ
Item features:
For use in special conditions. The stainless steel miniature ball bearing SS2-R2-ZZ / 2Z in inch-size is small and suitable for installation with limited space and on thin shafts. It is more corrosion resistant than AISI 420 (SS) alloy ball bearings.

Features
- all components are made of stainless steel: the miniature ball bearing has therefore better corrosion resistance to mild media (e.g. fresh water) than SS-bearings and is hygienic.
- miniature ball bearing with smallest dimensions
- suitable for high radial loads and light axial loads in both directions
- suitable for high running accuracy and quiet running
- seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z)
- 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)
