What Is A Ceramic Bearing

Boca bearings is the leader in ceramic and ceramic hybrid bearing technology for industrial and recreational applications.

What is a ceramic bearing.

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. Although the ceramic balls will not be affected by rust the steel casings of each bearing are still vulnerable to the elements. It is required to prevent bearing seizure when it warms up and expands. Are ceramic bearings waterproof.

On ceramic bearings this is usually a c3 clearance whilst on steel it s usually cn. Rolling resistance is the key trump card promoted by ceramic bearing fans. 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. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.

The bearing clearance is a measurement given to the small gap between the inner race outer race and balls. The coefficient of friction for unlubricated zro2 bearings at ambient temperature in air with a light load is approximately 0 0012. However ceramic bearings do not perform well when lubricated with grease lubricant. However ceramic ball bearings have emerged and are being used in a variety of.

Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls. Because ceramic bearings are rounder with a smoother surface and more uniform size friction is reduced and that can contribute to a less energy required to turn the cranks or spin the wheels. Performance ceramic bearings have an enemy. A ball bearing is a piece of equipment that uses balls to reduce friction in a spinning system.

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