ETP-HYLOC Keyless Shaft Locking Bushings

Featuring hydraulic quick connectors for mounting, the ETP-HYLOC Keyless Shaft Locking Bushings have a hydro-mechanical design. This feature makes it faster and easier to install as compared to purely mechanical designs that have many fasteners requiring a high tightening torque, often being mounted in a confined working space. It has radial and axial ports for use in mounting, giving it versatility for mounting in tight spaces.

It provides a robust hub-shaft connection in the most challenging operating environments while providing high torque and high radial load capacity, as well as excellent concentricity. Also important, the ETP-HYLOC with the “Plug & Play” feature can allow for fast changeout of the mounted component or quick repositioning either rotationally or linearly along the shaft, all while maintaining precise concentricity of the mounted component.

Available for shaft diameters from 2 to 8.7 in. (50 to 220 mm), it is designed with an internal double-walled steel sleeve having a straight cylindrical diameter at the ID and OD, which encloses an internal piston. When pressurized using a hydraulic pump, the ETP-HYLOC’s tapered piston is moved, expanding the inner and outer sleeves uniformly against the shaft and hub to form a continuous and rigid connection to the shaft.

ETP-HYLOC from Zero-Max is ideal for heavy-duty applications including steel bar peeling machines, tube straighteners, pavement grinding/grooving equipment, and other applications requiring high torque, high radial load capacity, and a high level of concentricity.
