This full ceramic bearing is made from good quality Zirconium Oxide (ZrO2) material. The bearing ball has a high precision grade of G5.This type of bearing can run without any lubrication and has been widely used in water submersible and high temperature applications. Full ceramic bearing can last up to approximately 10 times longer than a typical bearing.

Due to their non-conductive nature, it can help reduce the risk of electrical discharge damage and fluting.

Fluting is often associated with electrical discharge damage, which can occur when there is stray electrical current passing through the bearing due to factors such as improper grounding or electrical discharges in the surrounding environment.

This 20 x 37 x 9 mm (6904) bearing is a full ceramic bearing with Sealed Both Sides.
