Finished Bore Sprockets per American Standard
Hub size may require smaller setscews in some instances
Because these Type B sprockets are manufactured in quantity, they are more economical to purchase than the re-machining of stock-bore sprockets, with re-boring, and installing the keyway and setscrews. Finished Bore sprockets are available for Standard "B" Type where the hub protrudes on one side. The Type B Sprockets are also available in a variety of materials. We have access and can quote you Stainless "B" Type, Double Pitch "B" Type, Single Type “B” Double sprockets and Metric Type “B”.
Keyway is on “center line of tooth” so the sprockets are timed and will run together or as sets.
Our Finished Bore Type B Sprockets are ready for immediate installation. These are used with our Roller Chain.
The Sprockets are completely finished to the bore of the shaft diameter requirement and have a keyway and set screws. The exception to this is some of the ½” bore Type B sprockets do not have a keyway.
