Shaft-locking bushings

ETP shaft-locking bushings from Zero-Max produce accurate and concentric mounting compared to mechanical shaft-locking bushings. The devices lock into position gears, pulleys, and sprockets. They incorporate a double-walled sleeve that encapsulates a pressure medium. When the actuation screw is tightened, it forces the bushing’s inner and outer wall to expand uniformly against the shaft and hub of the mounted component. The result is concentricity to 0.001 in TIR (total indicator reading). The bushings are suitable where repeated mounting and dismantling of components is required. The ETP Classic operates from 40 to 11,413 lb·ft, while the ETP Express handles ranges from 40 to 6400 lb·ft.
