Features
- designed as hybrid miniature ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel
- lighter than comparable miniature ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; has a high wear resistance
- 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
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for 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)
