Features and Benefits of Trantorque Keyless Bushings
The unique Trantorque 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 to provide repeated component mounting/removal, reduced assembly time and
maintenance costs. The Trantorque 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. With Trantorque, 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.

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.

Eliminate key wallowing, backlash,
and fretting corrosion
The mechanical shrink fit design resists shock and torque reversals eliminating
key wallowing, backlash, and fretting corrosion associated with keyed fits. The
result is longer component life and reliability than with a keyed mount.

Precise axial and radial component positioning
The unique single nut positive lock and release action permits precise
axial or radial positioning of a component on a shaft. Trantorque can easily be
adjusted or moved, and allows for infinite positioning that's critical on those
applications that require synchronization or timing.

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