A Type (no hub) typically used in Agricultural Roller Chain Sprockets weld-on applications.
B Type (hub on one side) found in applications where clearance width is narrow. Typically have two (2) setscrews on the hub to fasten the sprocket to shaft and keyway.
Split Style Construction – Once you utilize a Split Sprocket, you may never want to use a setscrew mount style again. Removal or installation is a breeze. Can be used in virtually all applications. Another advantage to Black Ace’s split sprockets is certainly that the shaft/keyway protection is much tighter than a typical setscrew mount.
Split Style Narrow Width – Benefit from the benefits of split style building and keep carefully the total sprocket width just slightly wider than the sprocket tooth thickness.
Hex Bore Split Style – Used in apparatus that uses hexagon shafts.
Idler Design – Assembled with a long-lasting Black Ball Bearing
