High Precision Miniature Ball Bearing SS R144 ZZ / 2Z CN V2 P6 OIL1 3.175x6.35x2.779 mm
Item number:
SS-R144-ZZ-CN-V2-P6-OIL1
Item features:
The precision miniature ball bearing SS-R144-ZZ / 2Z-CN-V2-P6-OIL1 made of stainless steel, in inch size, 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 seal are possible. The main dimensions correspond to DIN 625-1.

Features
- all components are made of stainless steel: the miniature ball bearing is therefore corrosion resistant and hygienic
- 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
- vibration class: V2; lower tolerances with regard to occurring vibrations during operation
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
