Zero-Max Introduces ETP Hydropress
April 26, 2013—ETP Hydropress from Zero-Max provides quick and precise fastening of components in tight spaces on large shafts from 80 to 200 mm 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 to 200,000 ft. lbs., ETP Hydropress bushings utilize hydraulic pressure contained in a double-walled sleeve to lock components into position on a shaft. Utilizing a grease pump for mounting, both radial and axial connection to the shaft is easily made. Once mounted and pressurized, the conical angle of the outer sleeve locks the device into position forming a very tight, continuous connection between the shaft and mounted component.The bushing aligns precisely without axial movement as it is pressurized.The Hydropress can be reset at different positions on the shaft without losing concentricity. Transmittable torque can be varied by altering the mounting pressure. A flange on the Hydropress has two valves – one for the pump connection and a pressure release valve for dismantling. Available in custom sizes and stainless steel, these ETP Hydropress bushings are a cost-effective choice for new and retrofit applications including food processing and packaging applications.
