Heavy duty models of the ETP Express keyless shaft bushings are now available in 20, 40 and 60 mm sizes. Available from Zero-Max, ETP Express shaft locking bushings provide fast and frequent mounting/dismounting capabilities with only one radial screw. This saves space in a system and provides accurate mounting without axial movement of the ETP bushing along the shaft.
Providing up to four times the radial load capacity of the standard ETP Express models, these new heavy duty models are designed to provide a tight connection between the shaft and mounted components. When tightened, ETP’s radial screw compresses a pressure medium with the double-walled sleeve that expands and creates a solid connection between shaft and the mounting member. ETP’s uniform surface pressure prevents damage to surfaces and enables the use of shafts without problem-causing keyways. The single adjusting screw design makes the ETP Express superior to conventional mechanical locking bushings where numerous adjusting screws are required and axial movement of the mechanical bushing occurs when the screws are tightened.
Providing concentricity to .001 inch T.I.R., these ETP Express Bushings handle torque ranges from 40 to 6400 lbs. They are ideal for use in tight areas. An Allen wrench is the only tool required to torque, mount and lock these bushings into place. They position in seconds and can be readjusted many times just as quickly and without any axial movement of the bushing or component along the keyless shaft.
ETP Express bushings require no lubrication. They are easy to keep clean and handle a temperature range from -22° to 180° F. In addition to new heavy duty sizes, they are available in a full range of inch and metric sizes and in stainless steel metric sizes.
