Features
- tolerance class: P6 - high dimensional, form and running accuracy
- miniature ball bearing with smallest dimensions
- suitable for radial loads and light axial loads in both directions
- provides high running accuracy, quiet running and very high speeds
- vibration class: V2; lower tolerances with regard to occurring vibrations during operation
- cage material: sheet steel, high load-bearing capacity and high strength; suitable for continuous high temperatures
- seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
