Model Number: 8x22x7-#8997
Key Specifications/Special Features:
ZrO2 full ceramic bearingFull ceramic bearing use a combination of traditional 52100 steel rings precision matched with silicon nitride (ceramic) balls. In addition to being excellent electric insulators, hybrid bearings have a higher speed capability and will provide longer service life than all-steel bearings in most applications.ApplicationsCeramic ball bearing is widely used in metallurgy Kiln and glass, paint spraying equipment or blast furnace burden High temperature operating machinery.AdvantagesPrevent electrical arcingWhen electrical current passes across bearings, a washboard pattern appears on the raceways, along with a darkened grey appearance. Typical results include bearing surface damage, premature aging of the lubricant. The natural insulating properties of ceramic material eliminate this type of damage.
Lower maintenance costs
Extending the service life of a bearing without increasing maintenance cuts equipment operating costs.
Increase service life
Because of the properties of ceramics, a hybrid bearing's service life can be up to 10 times that of a standard steel bearing.
Extend grease life
Hybrid bearings run cooler and can operate with thinner lubricant films than conventional bearings.
Lower operating temperatures
Because ceramic balls are only 40% as dense as steel balls, the centrifugal load that they generate is less and the internal bearing friction is lower.
Reduce wear from contamination
Solid particle contaminants can create dents in bearing rolling surfaces.
