[QUOTE="Netherfield, post: 6687120, member: 6536"] It's a sprag or ratchet bearing, designed to stop something running the wrong way, we had one fitted to a bag elevator, it could have up to 6 x 10 stone bags on it, if for any reason the elevator was stopped with a load on it would try to run back downwards, this would pick up speed and run the motor above it normal speed, if someone tried restarting the elevator at his point the motor if single phase would now run in the wrong direction, or if three phase would try to go it's correct rotation but not be able to. Or EB used to fit them to some of their centreless auger systems which over a great length could turn the auger into a spring which then made the motor struggle on it's next start up. [/QUOTE]
