Ceramic Bearing Material

Types of ceramic bearings offered by sceram sceram offers all standards of ceramic bearings in three different material categories.

Ceramic bearing material.

The most common ceramic material used is silicon nitride. 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. Furthermore the weight of ceramic bearings is also lighter. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.

There are a number of commercially available ceramic bearing types grouped into one of two categories. Hybrid bearings consist of ceramic rolling elements in steel races whilst all ceramic bearings have both races and rolling elements made from ceramic. Typically all ceramic bearings are used in specialist high temperature high speed applications where the design requirements are very strict and hence can be costly. Balls made from this material are hard up to rc78 and have a very smooth surface.

These bearings offer several benefits over conventional steel bearings including enhanced acceleration capability increased stiffness and reduced friction. Bearings made with ceramic materials fall into a specialty niche in the bearing industry. The most common arrangement is a hybrid bearing usually with stainless steel rings and ceramic balls. Full ceramic bearings are usually made of following materials.

Ceramic bearings hard surfaces at high temperatures waukesha bearings applies ceramic and cermet ceramic metallic composite materials to thrust and journal bearing designs to extend bearing capabilities in applications where traditional materials and polymers fall short.
