The air shaft seal TRANSMITS AIR from the air supply to the rotating members of air clutches and air brakes making possible new applications of air clutches and air brakes previously considered impractical for closed-end shafts. The SLIP-ON INSTALLATION eliminates long rifle drilling of air passages in shafts and permits easy installation.
