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.
