Product description
This Tsubaki roller chain sprocket includes a 3/4-inch pitch, fits size 60 chains, and is single strand with one group of teeth around its circumference for use with single strand chains. It really is a Type B sprocket with a hub projection encircling the bore using one side, and both hub and bore have Quick-Disconnect (QD) fittings for inserting and locking into place different QD bushings based on the diameter of the 
A roller chain sprocket is a thin wheel with deep, uniformly spaced tooth ringing its circumference. The length from the peak of 1 tooth to the next is called the pitch, and is commonly measured in 1/8-in . increments. The sprocket transfers power and motion by a roller chain that is threaded over the teeth of the sprocket. The alignment of the chain with the sprocket’s pitch helps prevent the chain from slipping so that no power is usually lost. In the center of the sprocket may be the bore (hole) for sliding the sprocket onto a shaft, and a bushing or bearing is usually often suited to the sprocket’s hub to custom made-fit the sprocket onto a shaft to carry it firmly in place. A hub is certainly a protruding, raised lip encircling the bore of the sprocket. Sprockets with hubs on both sides are Type C, sprockets with hubs using one side are Type B, and sprockets with no hubs are Type A sprockets. For applications requiring sprockets to become swapped onto shafts of different diameters, a sprocket with a bore large enough to match all shafts can be used, with the gap between your bore and shaft closed with a bushing or bearing. Roller chain sprockets are found in a broad selection of applications where in fact the drive power of an engine needs to be transferred into motion, such as in automobiles, conveyors, escalators, agricultural, forestry and mining tools, aeronautics, robotics and space exploration, amongst others.
