Hybrid (Ceramics, Stainless Steel) High Precision Miniature Ball Bearing SS2 HC R144 ZZ CN V2 P6 GS1 3175x6.35x2779 mm
Item number:
SS2-HC-R144-ZZ-CN-V2-P6-GS1
Item features:
The hybrid precision miniature ball bearing SS2-HC-R144-ZZ / 2Z-CN-V2-P6-GS1 in inch-size is small and suitable for installation with limited space and on thin shafts. 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 rings are made of stainless steel and the rolling elements of ceramic. Therefore, it is lighter and withstands higher speeds.

Features
- designed as hybrid miniature ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel. It has better corrosion resistance to mild media (e.g. fresh water) than SS.
- lighter than comparable deep groove ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; withstands higher speeds and has a high wear resistance
- 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: stainless steel; corrosion resistant and 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
