Quick Detachable Bushing QT114

The QT114 is a steel quick-detachable bushing with a 1 1/4 inch bore for keyed shafts. It fits QT-series hubs and comes with two Grade 5 cap screws for a secure clamping fit. Maintenance teams use it to mount pulleys, sprockets or gears without heating or hammering the component onto the shaft.

Thermals Noise Power

As a passive mechanical component the bushing generates no heat, produces no audible noise and draws no electrical power during operation. Its steel construction and SAE Grade 5 hardware maintain clamping force across normal industrial temperature ranges without thermal management.

Upgrade From Press Fits

This bushing replaces pressed-on or set-screw hubs where frequent change-outs are required. The split-flange taper releases cleanly so the same shaft can accept different driven elements with minimal downtime. The jump is worth it when equipment must be reconfigured regularly or when shaft damage from removal forces must be avoided.

Questions about this item

How do I install the QT114 bushing on a 1 1/4 in keyed shaft and which step is often missed?

Slide the split-flange steel bushing onto the shaft, align the 1/4 in keyway with the shaft key, then torque the two included 1/4-20 x 1 in cap screws evenly to draw the 3/4 in per ft taper tight; the step most often missed is tightening both screws in stages so the 1.625 in bushing diameter seats uniformly.

What maintenance or replacement will the QT114 bushing need over time?

Inspect the 1/4 in wide by 1/8 in high keyway and the 1/4-20 cap screws during scheduled downtime; replace the bushing if the keyway walls show fretting or the 2 in bolt circle holes elongate, otherwise re-torque the cap screws to the original specification.

What is the first limit that appears when the QT114 bushing runs under sustained load?

The 3/4 in per ft taper relies on friction between the 1.625 in bore and the shaft; under continuous torque the limiting factor is taper slip once the clamping force of the two SAE Grade 5 cap screws is overcome.
