A Type (no hub) typically found in weld-on applications.
B Type (hub using one side) found in applications where clearance width is narrow. Routinely have two (2) setscrews on the hub to fasten the sprocket to shaft and keyway.
Split Style Structure – Once you utilize a Split Sprocket, you might never want to use a setscrew mount design again. Removal or set up is a breeze. May be used in practically all applications. Another advantage to Dark Ace’s split sprockets is usually that the shaft/keyway protection is much tighter than a typical setscrew mount.
Split Style Narrow Width – Enjoy the advantages of split style construction and keep the total sprocket width just slightly wider than the sprocket tooth thickness.
Hex Bore Split Style – Used in Agricultural Roller Chain Sprockets apparatus that uses hexagon shafts.
Idler Design – Assembled with a long-lasting Black Ball Bearing
