摘要
In combination, a guide post, a coaxial ball bearing cage adjustably receiving the guide post and adapted for longitudinal and rotary movements. A coaxial guide sleeve upon a support adjustably receives the cage and post. A coiled spring within the sleeve is mounted upon the support and yieldably supports the ball cage. An apertured cap upon the sleeve loosely receives the cage and has an inlet adapted for connection to an air source. Pressurized air is directed into the cap for angular impingement upon the cage for rotating the cage relative to the sleeve. As a modification the spring is replaced by a pressurized air source.
