Hybrid Ceramic Bearings Maintenance

Hybrid ceramic bearings have traditional 52100 steel or stainless steel rings with ceramic silicon nitride si3n4 balls.

Hybrid ceramic bearings maintenance.

This characteristic is known as adhesive wear. The initial cost of a hybrid bearing may be higher than a standard steel bearing but the difference is quickly recovered in maintenance savings. Ceramic hybrid bearings are widely used in electric motors aerospace applications performance racing vehicles laboratory equipment under water applications and more. Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride si 3 n 4 which make the bearings electrically insulating.

It will fill in the pores pits and gaps typically found in chrome or stainless steel. The savings in reduced maintenance costs alone can be significant. A 10 20 fill is more than sufficient but be sure to not over lube. The robust design together with a combination of steel and ceramics makes the bearings useful for many different applications.

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 reducing the need for maintenance on your machine as well as the costly interruptions in production. There unmatched durability gives the hybrid ball bearings a life expectancy ten times that of steel. Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions. Depending on application bearing service life can be up to five years longer.

Overall accuracy and quality. Soaking bearings for 10 15 minutes in lbt bearing soak will reduce friction decrease wear and extend life. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. Hybrid bearings using ceramic balls are designed for applications where high grade electrical isolation is necessary and or high speeds occur.

Ceramic hybrid bearing applications. Hybrid ball bearings may be a bit more expensive than their steel counterparts but the extra costs are quickly recouped. They lower operating and maintenance costs and increase efficiency ultimately increasing profits. So although bearings are a relatively minor investment in themselves their reliability and durability are central in keeping your production running.

Because wear particles generated by adhesive wear are not present in ceramic hybrids lubricant life is also prolonged. Any application that requires higher speeds lower friction and longer life are ideal for ceramic hybrid bearings. The final step is lubrication. Since ceramic balls will not cold weld to steel rings wear is dramatically reduced.

A ceramic bearing is also harder than steel bearings up to 30 which improves durability and they also don t rust so less maintenance should be required. Today producers are turning to hybrid ball bearings in which the balls themselves are produced from extremely tough and durable ceramics.
