High Precision Miniature Ball Bearing MR 148 ZZ / 2Z CN V2 P6 OIL1 8x14x4 mm
Item number:
MR-148-ZZ-CN-V2-P6-OIL1
Item features:
The precision miniature ball bearing MR-148-ZZ / 2Z-CN-V2-P6-OIL1 meets even the highest demands. It is sealed on both sides, versatile and can carry radial and light axial loads. Due to the metal seal even higher speeds than with comparable miniature ball bearings with rubber seal are possible. The main dimensions correspond to DIN 625-1.

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
