Balls

The balls used in HQW bearings are usually made of stainless steel (X65Cr13). However,for particularly arduous applications, many of our bearings are fitted with ceramic balls made from silicon nitride (Si3N4).

Only balls of grade 3 and 5 are used for HQW spindle bearings. These classes comply with the highest tolerances in terms of size, roundness and roughness.
