The present report describes the results of experimental studies on the dustproof performances of several wipers for ball screws. All the wipers for the experiments used in the study have already been put into pratical use. The results may be summarized as follows : (1) The dustproof performance of a metal wiper improves as its radial clearance is decreased. (2) If a resin wiper is assembled into a ball screw being lightly pressed against a screw shaft raceway, almost the same effect as a metal wiper is obtained in dustproof performance. (3) A brush wiper is improved in dustproof performance and its durability as compared with a felt wiper, but their contact friction torques become so large that they can no longer be disregarded as compared to the friction torque of a ball screw.
