Mechanical Product: Pressure-Medium Bushings

ETP Express bushings lock components to keyless shafts by pressurizing a medium inside the double-walled bushing sleeve and flange.

The walls of the bushing expand and clamp components to shafts with a precision of less than 0.0008-in. runout. The pressure is adjusted by means of a radially oriented Allen screw.

The bushings handle torques from 39 to 6,416 lb-ft and axial loads from 1,506 to 47,212 lb. English diameters from 0.625 to 2 in. and metric diameters from 15 to 80 mm are available. Standard bushings are formed from hardened steel. Optional stainless-steel bushings come in metric sizes from 15 to 50 mm supporting torques from 34 to 1,400 lb-ft. Both materials withstand temperatures from –22 to +180°F.
