The Amtec Hydraclamp Step Nut provides accurately controlled pre-tensioning service for tie-rods, shafts and arbors in rolling mills, pinion stands, hearing equipment and presses. Compact, highly efficient and single-acting, Amtec Step Nuts can be hard piped or plumbed through quick disconnect GX-Nipple and Coupler connections. For short periods of up to three weeks, internal pressures will be reliably constant. Pressure monitoring systems, such as our Series 550 Transponder can be added where longer in-service periods are required.
