Keyless bushings

Mount and install components such as gears, couplings and rollers easily with a Keyless Bushing.

A Keyless Bushing offers flexible and easy installation, while providing exceptional holding power. The unique Keyless Bushing is a prime example of offering a competitive edge for equipment design and operation. It allows components to be securely mounted and accurately positioned on a shaft in seconds without the need for a keyway. Expertly designed, it provides repeated component mounting/removal, reduced assembly time and lower maintenance costs. The keyless concept provides a wealth of benefits.

Mount components without keys, keyways and setscrews

Machining keyways or flats creates a weak spot in the shaft. A keyway does not have to be cut in the shaft, a given shaft size can transmit greater torque, or you can downsize both the shaft and components, reducing size, weight, and cost. In addition, because tolerances are not as critical as with a keyed mount, a less expensive shaft can be used. In fact, an unfinished shaft is preferred.

Keylesss units can also be used directly over empty keyways to repair a worn or damaged connection. Both "inch" and "metric" units are available, making it easy to return both domestic and foreign machinery to service quickly.

Mount hubless components

A unique feature is the ability to mount hubless components. The precision-machined outer element ensures a perpendicular, flat mounting face. This allows the use of plate sprockets, hubless gears, disc brakes, etc., often at substantial cost savings. Problem weld-on hubs are a thing of the past.
