Zero-Max ETP Hyloc shaft locking bushings for steel processing systems
May 16, 2013 – Forming steel into different-sized bar stock requires positioning and fastening a system’s roll-forming wheels with accuracy so they stay aligned throughout the process. The ETP Hyloc from Zero-Max promises just that: a hub-shaft connection in these difficult operating environments, providing concentricity despite high torque and radial loading of the system. Easily adjustable, says Zero-Max, the Hyloc can be repositioned on the shaft or removed for changing to another roll-forming wheel size, minimizing downtime. Available for shaft diameters from 50 mm to 220 mm, the ETP Hyloc is designed with an internal, double-walled steel sleeve that encloses a conical-shaped moveable piston. When pressurized using a hydraulic pump, the sleeve expands uniformly against the shaft and hub to form a continuous and rigid connection to the shaft.
