Application:

G5 grade balls:

Balls are the first factor for vibration of the bearing. Surface quality of the ball and waviness is a necessary condition for producing low-noise bearing. We use G5 grade balls by image inspection each.

Grinding Accuracy:

Strict control of ring curvature below 15um lead to constant fan speed, current and power consumption.
