Heavy duty models of the ETP Express keyless shaft bushings are available in 20, 40 and 60 mm sizes. The units provide fast and frequent mounting and dismounting capabilities with only one radial screw. This saves space in a system and provides accurate mounting without axial movement of the unit along the shaft. The products are designed to provide a tight connection between the shaft and mounted components. When tightened, the radial screw compresses a pressure medium with the double-walled sleeve that expands and creates a solid connection between shaft and the mounting member. Uniform surface pressure prevents damage to surfaces and enables the use of shafts without problem-causing keyways. Providing concentricity to .001" T.I.R., the units handle torque ranges from 40 to 6,400 lbs. An Allen wrench is the only tool required to torque, mount and lock the products into place. They require no lubrication, are easy to clean and handle a temperature range from -22° to 180° F. They are available in a full range of inch and metric sizes, as well as in stainless steel metric sizes.
