Ultra High Speed Angular Contact Ball Bearings with SURSAVE™ Cage

Ultra High Speed Angular Contact Ball Bearings with SURSAVE™ Cage

Optimized cage design realizes low vibration and low torque at high speeds.

High performance SURSAVE cage achieves low NRRO (Non-Repeatable RunOut), low torque, and low heat generation. Bearings with SURSAVE cage realize high speed performance (3 million dmN) with oil-air lubrication. High-precision P3W-class for high rotational accuracy and low heat generation achieves superb machining quality and efficiency across a wide range of applications.

Ultra High Speed Angular Contact Ball Bearings With Newly Developed SURSAVE Cage

Features

1. Compared with conventional products reduced NRRO (Non-Repeatable RunOut) by 50% at high speeds, and torque by 20% for low heat generation.

2. Robust series BNR and BER types are now available in a wide range of sizes (30-110 mm bore diameter).

3. P3W class is a high precision model with rotational accuracy compliant with ISO Class 2 and reduced deviation of width dimension. The series offers high rotational accuracy as a standard feature.
