TB Woods SK178 Bushing, 1-7/8" bore

TB Woods SK178 Sure-Grip sheave bushing, 1-7/8" bore. 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 ft. on the diameter) which is about half the inclined angle of many other bushings.

The result is 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 interchangeability extends through sheaves, pulleys, timing pulleys, sprockets, flexible and rigid couplings, made-toorder items by Wood’s, 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.
