<p>Disclosed is a method of forming a rail (24) for use in a linear motion bearing assembly which comprises the steps of: extruding an elongate base member (26a) having a pair of substantially vertical arms (28a) having respective inner surfaces with a pair of undercut longitudinal groves (32a) therein and a pair of upper flanges (40a), said vertical arms being flexible with respect to said base member; providing a pair of flexible load bearing inserts (34) having outer and inner surfaces, said outer surfaces defining a plurality of parallel grooves to form load bearing tracks (38), said inner surfaces (36) defining longitudinal reliefs to enhance flexibility; positioning said load bearing inserts (34) in said undercut longitudinal grooves (32a), and crimping said upper flanges (40a) to cause elastic deformation of said load bearing inserts without causing substantial plastic deformation thereto to secure said load bearing inserts. <IMAGE></p> |
