Bearings are sealed to retain lubricant
The rotation speed is faster, the ceramic ball has oil-free self-lubrication, and the friction coefficient of the ceramic ball is small, so the rotation speed of the ceramic ball bearing can reach 1.5 times or more.
Long life: Since it does not use grease and uses ceramic balls, it has a lifespan 2 to 4 times longer than ordinary bearings.
Insulation. Ceramic ball bearings insulate the inner and outer bearing rings.
