Hybrid ceramic bearing configuration: inner and outer ring bearing steel / stainless steel + ceramic ball + PA66 / stainless steel retainer +2RS / ZZ.
Advantage
(1), high temperature resistance, ceramic ball thermal expansion coefficient is small, in the high temperature environment will not cause the bearing ball to expand due to temperature, which greatly improves the use temperature of the entire bearing, the temperature of ordinary bearings is about 160 degrees, ceramic ball Can reach more than 220 degrees.

(2), the rotation speed is high, the ceramic ball has oil-free self-lubricating property, and the ceramic ball has a small friction coefficient, so the ceramic ball bearing has a high rotation speed. The bearing using the ceramic ball is the rotation speed of the general bearing of 1.5 times or more.

(3). Long life, ceramic ball can be added without any grease, which means that even if the grease is dry, the bearing can still work, thus avoiding the premature bearing damage caused by the dry grease in the ordinary bearing. The test and some customer feedback use the ceramic ball after the bearing life is 2-3 times that of ordinary bearings.

(4) The last point is also the most important point. Insulation. Bearings made of ceramic balls can insulate the inner and outer rings of the bearing. Because the ceramic balls are insulators, ceramic balls can be used between the inner and outer rings of the bearing to achieve insulation. The effect. This allows the bearing to be used in a conductive environment.
