Special Environments Require Ceramic Bearings

Everybody knows that bearing materials are various. Different disadvantages, advantages, and functions are there in various kinds of materials. Used for producing bearing products, Steel is a main kind of material. But this material cannot be performed well in some environments.

Many specific advantages are there in ceramic balls Compared to steel. They offer superior heat resistance and corrosion, lower density, and higher dimensional stability, which offers high speed. In corrosion and heat resistance, Ceramics are lightweight and extremely hard superior to steel.

Consequently, in environments where conventional steel bearings cannot, ceramic rolling bearings can be used. Making it possible that they can be applied in some special environments, the superiority of these bearings is worth.

Firstly in corrosive environments, they can be used. All ceramic ball bearings lasted three and twenty times longer respectively Compared to stainless steel bearings. Leading to extended bearing life, it is presumed that water readily forms a better lubrication film and adheres to silicon nitride.

Secondly, in corrosive agents, they can be performed. Generally, excellent corrosion resistance is in silicon nitride. However, depending on the quantity and type of sintering additives, corrosion resistance varies and certain corrosive agents decrease in flexural strength and hardness. In such a situation, it is can be proved that the most effective are the carbide-based ceramic bearings.

Thirdly, in a high-temperature vacuum, they can be used. In a high-temperature vacuum environment, in durability, an all-silicon nitride ball bearing with a self-lubricating laminated cage and with MoS2-coated rings and balls proved superior. Compared with the hybrid bearings, in both dynamic life and frictional torque, the full the ceramic ball bearing was superior.

Fourthly, with poor lubrication, they can be performed. In bearing life without lubrication, they outperform other materials like ceramics have outstanding wear resistance and are extremely hard.

According to a test, though sustaining wear, did not, the steel bearing seized within a short period while the all-ceramic and hybrid bearings. Indicating that its endurance life is much longer, as compared to the hybrid bearing, the all-ceramic bearing sustained considerably less wear.
