Guide post, guide sleeve and improved air impulse rotary ball cage assembly

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. An apertured cap or ring upon the sleeve loosely receives and rotatably supports the cage. An inlet on the cap is adapted for connection to a pressurized air source. Pressurized air is directed into the cap for angular impingement upon the cage for rotating the cage relative to the sleeve.
