What Is A Ceramic Bearing

However ceramic bearings do not perform well when lubricated with grease lubricant.

What is a ceramic bearing.

Performance ceramic bearings have an enemy. Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls. It is required to prevent bearing seizure when it warms up and expands. Although the ceramic balls will not be affected by rust the steel casings of each bearing are still vulnerable to the elements.

The bearing clearance is a measurement given to the small gap between the inner race outer race and 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. 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. On ceramic bearings this is usually a c3 clearance whilst on steel it s usually cn.

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

A ball bearing is a piece of equipment that uses balls to reduce friction in a spinning system. Are ceramic bearings waterproof. The coefficient of friction for unlubricated zro2 bearings at ambient temperature in air with a light load is approximately 0 0012. Full ceramic bearings have a very low coefficient of friction compared to steel bearings or even hybrid bearings.

Rolling resistance is the key trump card promoted by ceramic bearing fans. While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4. 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 balls and rolling elements in a ball bearing are traditionally made of steel.
