Low noise high precision steel balls are high grade steel balls that have a highly spherical form and a smooth surface, normally utilized in high precision ball bearings like: deep groove ball bearing, Angular contact ball bearing, ball thrust bearing, four-point contact ball, Self-aligning ball bearing. Low noise high precision steel balls should have basic properties such as long life spam, low vibration, low noise, low rotational torque and high reliability. To achieve the above performance, it is necessary to ensure the quality of all bearing parts, above all, the steel balls.
