Sure-Grip® “Quick Detachable” bushings are easy to install and
remove. They are split through flange and taper to provide a true
clamp on the shaft that is the equivalent of a shrink fit. All sizes
except JA and QT have a setscrew over the key to help maintain
the bushing’s position on the shaft until the cap screws are securely
tightened. Sure-Grip bushings have a very gradual taper (3/4-inch
taper per foot on the diameter) which is about half the inclined
angle of many other bushings. The result is that the Sure-Grip
securely clamps the shaft, with twice the force of those competitive
bushings, to provide extreme holding power.
Versatile Sure-Grip bushings permit the mounting of the same
mating part on shafts of different diameters, and the mounting
of different sheaves on the same shaft using the same bushing.
Their interchange ability extends through sheaves, pulleys, timing
pulleys, sprockets, flexible and rigid couplings, made-to-order items
by Veyance Technologies, and to product lines of several other
mechanical power transmission manufacturers.
Sure-Grip bushings are manufactured with the drilled and tapped
holes located at a precise distance from the keyseat; thus, a wide
mating part having a bushing in each end can be mounted on a
common shaft with the two keyways in line. This feature not only
facilitates installation but also permits both bushings to carry an
equal share of the load.

6-hole drilling
(most sizes) makes
installation and
removal quick
and easy.
Precise taper ( 3/4 in. per ft.
on diameter) provides proper
wedging action.
Saw cut through flange
and taper (and sometimes
cut down into keyway
also) to provide a
true clamp fit.
