The Posi-Lock Manual Gear/Bearing Puller locks on a rounded surfaces or grips on a small groove without its jaws snapping back or flying off. Because all jaw functions are controlled by the device's external safety cage, the user simply turns the T-handle to open, close, align, and lock the jaws, which are designed to stay locked until the pulling process is complete and the puller is released from its grip. The manual puller is available in numerous two- and three-jaw models that have varying spreads, reaches, and pulling capacities to fit the specific tasks. There is also a line of hydraulic-operated pullers where physical limitation and/or job size dictates.
