April 17, 2013 – Zero-Max says its ETP Hydropress quickly and precisely fastens components in tight spaces on large shafts from 80 mm to 200 mm in diameter. Hydropress shaft bushings are suitable for locking into position gears, sprockets, pulleys and similar components in a machine’s power transmission system. Handling torque ranges from 21,000 ft-lb to 200,000 ft-lb, ETP Hydropress bushings employ hydraulic pressure contained in a double-walled sleeve to lock components into position on a shaft. Both radial and axial connection to the shaft is made utilizing a grease pump for mounting. Once mounted and pressurized, the conical angle of the outer sleeve locks the device into position forming a tight, continuous connection between the shaft and mounted component. The bushing aligns precisely without axial movement as it is pressurized.
