ABSTRACT:
A telescoping or linear motion ball bearing synchronized slide mechanisms having inner and outer slide members held together by ball bearings, the balls being operably disposed in a ball retainer between the inner and outer slide members and means for precisely maintaining the relationship of these parts. This means comprising strips of friction material secured to the inner sides of the inner and outer slide members and extending longitudinally of these slide members. The ball retainer has longitudinally spaced openings with rollers or holders operably mounted to the ball retainer at these openings and a continuous or endless flexible band of friction material is mounted on these rollers and extends longitudinally of the ball retainer. The ends of the band are looped and pass over the rollers so that the longitudinally extending portions of the band between the loops extend on respective opposite sides of the ball retainer in parallel relationship to the respective strips of friction material on the slide members and operably engage or mesh in a random manner the strips of friction material on the respective inner and outer slide members.
