ETP Express (Model R Stainless Steel) keyless shaft locking bushings feature high torque capacity. They are suitable for locking into position gears, pulleys, sprockets and other components in a machine's power transmission system. Handling torque ranges from 34 to 6,400 ft. lbs., these stainless steel ETP Express-R shaft locking bushings from Zero-Max work in systems requiring frequent washdowns because they are easily cleaned and won't corrode. They have sealed, clean lines that resist debris collection and clean easily without any special maintenance.
"The torque transmission capacity for these ETP Express-R stainless steel bushings is two-and-a-half times greater than conventional bushings. Their unique design made of stainless steel makes this possible," reports Robert Mainz, Zero-Max sales manager. "They are ideal for the high performance requirements of servo systems and especially systems where space limitations are present. They provide high torque transmission and have a very compact footprint."
ETP Express-R bushings feature just one radial actuation screw for fast mounting, repositioning and phasing of the components to the shafts. 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. An Allen wrench is all that is required to mount and lock these bushings into place.
The ETP Express' single radial tightening screw provides a solid and more precise connection between shaft and hub unlike conventional shaft locking bushings. The ETP Express-R incorporates a double-walled sleeve filled with a pressure medium. When the actuation screw is tightened, the hydraulic pressure medium in the sleeve expands the double walled sleeve, forming a very tight, continuous connection between the shaft and mounted component. The bushing aligns precisely without axial movement as it is tightened. Tightening numerous screws creates axial movement of the bushing and is less precise. Available in 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80 mm shaft sizes and 5/8", 3/4" 7/8", 1.0" 1-1/8", 1-1/4", 1-3/8", 1-1/2", 1-3/4", 1-15/16", 2.0" standard shaft sizes, stainless steel ETP Express-R bushings are a very cost-effective choice for new and retrofit applications particularly in food processing and dairy machinery power transmission systems.
