NSK Precision Bearings: 1.High precision bearing 2.Origin bearing 3.Can be used in pairs or groups

NSK Precision Bearings

NSK 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 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.
