What Is A Ceramic Bearing

Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls.

What is a ceramic bearing.

No ceramic bearings are self lubricating however in humid and coastal environments using a small amount to keep the steel casings free from rust is a common practice. Although the ceramic balls will not be affected by rust the steel casings of each bearing are still vulnerable to the elements. A ball bearing is a piece of equipment that uses balls to reduce friction in a spinning system. On ceramic bearings this is usually a c3 clearance whilst on steel it s usually cn.

The balls and rolling elements in a ball bearing are traditionally made of steel. Full ceramic bearings have a very low coefficient of friction compared to steel bearings or even hybrid bearings. While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4. However ceramic ball bearings have emerged and are being used in a variety of.

Grease lubricant is the most commonly used type of lubricant in the cycling industry because it provides consistent lubrication over a long period of time with little to no maintenance. The bearing clearance is a measurement given to the small gap between the inner race outer race and balls. Boca bearings is the leader in ceramic and ceramic hybrid bearing technology for industrial and recreational applications. Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

It is required to prevent bearing seizure when it warms up and expands. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic ball bearings are ball bearings that are made of ceramic rather than steel. 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.

The coefficient of friction for unlubricated zro2 bearings at ambient temperature in air with a light load is approximately 0 0012. Performance ceramic bearings have an enemy. However ceramic bearings do not perform well when lubricated with grease lubricant. Full ceramic bearings are also non magnetic meaning they can be used in medical devices such as mri scanners or any application where there is a strong magnetic field.
