摘要：
A helical groove for conducting lubricant is formed in an internal cylindrical surface of a bearing member by pressing a plurality of balls against the surface while effecting relative longitudinal and rotational movement between the bearing member and a ball-carrier which carries the balls. The balls roll along the cylindrical surface and press-form the helical groove therein. To enable the ball carrier to be inserted into the bearing, the balls are held in a retracted state by applying a vacuum to the balls.
