A Type (no hub) typically used in weld-on applications.
B Type (hub on one side) used 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 use 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. An additional benefit to Black Ace’s split sprockets is that the shaft/keyway security is much tighter than a typical setscrew mount.
Split Style Narrow Width – Enjoy the benefits of split style construction and keep the total sprocket width only slightly wider than the sprocket tooth thickness.
Hex Bore Split Style – Used in equipment that uses hexagon shafts.
Idler Style – Assembled with a long-lasting Black Ball Bearing
