All ceramic bearings have advantages such as high precision, wear resistance, and good thermal stability, and have gradually been introduced to the market and applied in various industries.
In some special situations, such as low speed and heavy load, impact load, dry friction state, and low temperature environment, all ceramic ball bearings will produce different dynamic characteristics, resulting in different radiation noise.
Due to its high stiffness, ceramic materials have a poor ability to absorb radiated noise, making the changes in bearing radiated noise more complex under these operating conditions.
Under low speed and heavy load working conditions, with the operation of the bearing, the rolling element is subject to alternating loads, and bears a large Contact force in the bearing area. Therefore, the bearing will produce large friction noise in the bearing area, while relatively large impact noise in the non bearing area.
