BEARING FOR STRAIGHT SLIDE AND METHOD OF SETTING THEREOF

Document Type and Number:

WIPO Patent Application WO/1990/010159

Kind Code:

A1

Abstract:

A bearing for straight slide and a method of setting thereof according to this invention are such that the setting surface (14) of a sliding base (B) on which a movable body (5) such as a table is fixed is provided with a minute curvature so that pitching of the sliding base (B) caused by the error in setting a rail base (2) may be absorbed and mitigated by utilizing elastic deformation of the setting surface (14) occurring when the movable body (5) is fixed, whereby precision in positioning the movable body (5) guided by the sliding base (B) can be improved.
