Run In Of Ceramic Bearings

Cooler running ceramic bearings have no micro weld adhesion between the balls races which means lower friction.

Run in of ceramic bearings. The natural insulating properties of ceramic material eliminates this type of damage. Ideal adapted materials in the bearing could even lead to a greater number of shoots with the same gas filling. Firstly when we say ceramics we mean hybrid ceramic bearings which are made up of ceramic balls running in steel races. The corrosion resistance of si3n4 full ceramic bearings is critical in wafer cleaning applications.

The cleaning medium is also used as lubricant for the bearings as the use of grease is forbidden. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Applications that involve high speeds and high loads often involve ceramic bearings. These bearings offer several benefits over conventional steel bearings including enhanced acceleration capability increased stiffness and reduced friction.

When electrical current passes across bearings a washboard pattern appears on the raceways along with a darkened grey appearance. Bearings run cooler and vibration levels are lower at high rpm. Hybrid ceramic bearings also offer the benefit of not allowing electrical currents to run through the bearing which allows for prolonged use. Secondly we are only addressing human powered equipment which operates at relatively low wattage inputs at low operating temperatures and at a measly 80 110 rpms.

In this application the bearings directly run in contact with aggressive process gases.
