ETP-HYLOC® Keyless Shaft Bushings

Keyless shaft bushings are the perfect solution for secure shaft-to-hub connections and are ideal for positioning and locking shaft components in a high-performance system. ETP-HYLOC keyless shaft bushings are designed for precision and provide the best solution where keyways and tapers can weaken or cause excess wear to shaft couplings.
ETP-HYLOC keyless locking devices from Zero-Max are hydro-mechanical joints consisting of a double-walled sleeve that encloses a conical moving piston. Mounting and dismantling are carried out with an external hydraulic pump (supplied separately). In the flange, there are three threaded connections (“ON”, “P”, and “OFF”) in the radial direction and the same in the axial. This makes it possible to choose a radial or axial connection of the pump hoses, depending on the build-in situation.
We carry keyless shaft bushings in several models to meet your power transmission application. Request a quote for the ETP-HYLOC keyless device that meets your torque requirements or contact us for additional information.
