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