All G&G QD Sprockets follow industry standards and are compatible with industry standard QD Bushings.

QD Bushings are precision machined, tapered and fully split on one side. The taper bored QD Sprocket easily fits over the tapered bushing, and tightening of the cap screws produces a tight press fit on the shaft. The sprocket is easily removed from the bushing by using the pull-up bolts as jackscrews in the holes tapped in the rim of the bushing. Bushings are double drilled for reverse mounting. 
 

QD Weld on Adapter may be welded to type A sprockets, fan wheels, steel disc pulleys, and many other rotating units. The OD of the adapter is straight to facilitate the location of the adapter and bushing with respect to the rotating unit. Care must be taken in welding so that the unit to which it is applied is true.
