ETP Express® shaft locking bushings minimize runout and system vibration. They provide a connection between keyless shafts and mounted components that can be installed in seconds, the co. states. Designed to lock gears, pulleys and other components to keyless shafts, the locking bushings have a low total indicated runout (TIR) of less than 0.02-mm. This feature minimizes component runout on rotating shafts, reducing machine vibration and noise. The locking bushings are designed with a double-walled hardened steel sleeve and flange filled with an actuating pressure medium. When tightened, a single radial screw actuates a piston to compress the medium, thus expanding the bushing walls and creating a solid connection between shaft and hub. The bushings are available in inch and metric sizes from 15- to 80-mm. and are RoHS compliant.
