Features
- all components are made of stainless steel: the miniature ball bearing has therefore good corrosion resistance to mild media (e.g. fresh water) 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: open (without seal) and easy relubrication
- 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)
