NSK Super Precision Bearings: 1.High precision bearing 2.Original bearing 3.Can be used in pairs or group
NSK super precision bearings
NSK super precision bearings to support precision ball screws,have better performance than earlier combineatioins
of angular contact ball bearings .They are especially suitable for high precision machine-tool feeding mechanisms
and similar application .
NSK super precision bearings features
1. Optimum design
Optimum design achieved by computer simulation of temperature rise resulting from ball skid.
2.Long life
Enhanced service life measures include raising the seizure limit under low lubrication and high-speed operating conditions.
3. High accuracy
Rolling element material can be tailored to match the application.
Ceramic balls are used for ROBUST series angular contact ball bearings.
Highly accurate P2 series is available.
4. High Speed
Cage engineered for high-speed operations. Benefits of the lightweight, high strength engineered resin cage include heat resistance and high rigidity, making this cage indispensable for high-speed applications.
5.Low Noise
Eliminates noise caused by compressed air of the oil-air lubrication system.
