chain sprocket

Finished bore sprockets provide increased avoidance of shaft slippage over minimum basic bore sprockets. Finished bores enable the roller chain sprocket to move larger loads with an increase of accuracy.

Toronto Gear Functions produces ready-to-ship completed bore sprockets that are manufactured with precision and are fast and simple to install. Our catalogue includes a agricultural Chain variety of finished bore sprockets that may match many precise functionality requirements.

Toronto Gear Works stocks steel finished bore roller chain sprockets for #25 (0.250” pitch) roller chain. We stock these metal sprockets in tooth counts which range from 9 to 72. Our finished bore sprockets with a 0.500” bore or smaller are supplied with two set screws. Our finished bore sprockets with a 0.625” bore or greater have a typical keyway and two set screws. The keyway can be devoted to the tooth and the set screws are located over the key at 90 degrees.

Steel finished bore #25 roller chain sprocket component numbers could be determined the following:

25BF + Tooth Count + “x” + bore size.

An example will be 25BF72x1-3/8. That is for a #25 roller chain. It includes a “B” style sprocket which implies that it has a hub. It includes a finished bore of 1 1.375” and it offers 72 teeth.
