Kwiklock Keyless Bushes: Versatile shaft clamping elements designed for speedy installation without the need for keys or keyways, simply slide over the shaft, position the gear, pulley or sprocket and tighten the locking nut. The bushes exert an incredible amount of grip onto the shaft and drive element and are almost impossible to get them to slip.
Benefits: No keys or keyways required, easily adjusted for alignment, facilitates easy maintenance access, very secure clamping.
Notes: Shafts and bores need to be parallel and have a reasonable surface finish, out of round or corroded surfaces will not provide the clamping forces required for these bushes to work correctly.
