Abstract

This invention relates to a manufacturing method for stainless steel linear bearings including the following steps: first of all cutting a stainless steel tube to a tubular stock, then turning it to a tubular inside wall with interphase axial concave arc side and axial salient small concave arc side to prepare a bearing ferrule after heat process and rough grinding, in which a holder is made by punching a stainless steel cold-rolled plate on a punch with a die to a blank plate, then punching a middle groove, pulling a rolling runner, then punching a ball bearing groove, cutting outskirt and shaping it precisely.

Description

technical field

[0001] The invention relates to a method for manufacturing a linear bearing, in particular to a production and processing method for a stainless steel linear bearing. Background technique

[0002] The ferrule of the ordinary linear bearing is made of GGr15 bearing steel special-shaped tube. After blanking, the inner and outer diameters of the ferrule are firstly positioned and processed within the tolerance range, and then the entire ferrule is heat treated, and then the inner and outer diameters are rough and finely ground. Circle accuracy requirements. The bearing cage is made of engineering plastics and is injection molded into a round tube by an injection molding machine. The steel balls of various specifications and the rubber dust cover are made of bearing steel. Before assembly, classify the bearing rings, and then assemble the finished product according to the sorting level. Because ordinary linear bearings cannot be used in special and harsh enviro...
