ABSTRACT:
A stroke bearing is able to perform relative motion along a prescribed path by itself without requiring the providing of a stopping device that prevents a ball and cage assembly from falling out on the apparatus. In a stroke bearing having an outer sleeve and a shaft fit together by means of a ball and cage assembly, by, for example, fitting a bushing into said outer sleeve, providing a guide groove on this bushing, and having a pin make sliding contact with said guide groove, said stroke bearing is able to perform relative motion along a prescriber path. In addition, the ball and cage assembly can be easily prevented from falling out by a stop ring acting in the manner of a range limiting device that limits the range of said relative motion.
