Rolling guide apparatus for e.g. machine tool, x y table, has sliding block main body formed of engineering and machinable ceramics

摘要

A sliding block main body (34) has a load rolling element rolling surface (31) and a parallel rolling element return path (33) connected by a turn path (35). A portion of the main body, containing the load rolling element rolling surface, is formed of engineering ceramics. The rest of the main body is formed of machinable ceramics.
