Are Ceramic And Steel Ball Bearings Made The Same Way

While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4.

Are ceramic and steel ball bearings made the same way. Tic coated balls retain the same elastic modulus as the parent material 440c stainless steel thus it will have the same rigidity as the conventional bearings. As rolling elements in such bearings are used balls made of ceramic. Ceramic balls are less prone to expansion than steel balls which means bearings with ceramic balls will be more precise than steel bearings and produce less vibration. In converse higher stiffness based on same internal geometry yields higher stresses.

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. Bearings with ceramic balls are more durable and less noisy. Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. The low coefficient of friction of ceramics increases the surface stability of the balls and increases the service life of the bearing as a whole.

Rolling resistance is the key trump card promoted by ceramic bearing fans. Ceramic balls have higher modulus thus greater stiffness. The hardness of ceramic balls also allows them to crush any particles that make their way into the ceramic ball bearing so they don t cause damage to the races. It is possible to find cheap ceramic or steel bearings on aliexpress or ebay i trust those the same way i trust the 30 carbon handlebar for mountain bikes that is advertised on the next page.

The c hip ceramic balls are similar to our si3n4 ceramic ball series but these c hip balls are made with by hot isostatic pressing hip.
