- J Series QD Bushing
- 3.875 in Bore Size
- 6.25 in Bolt Circle
description
- Sure-Grip® Quick Detachable bushings are easy to install and remove. Split-through flange and taper provide a true clamp on the shaft that is equivalent to a shrink fit. All sizes except JA and QT have a set screw over the key to help maintain the bushing’s position on the shaft until the cap screws are securely tightened. 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.
