A Type (no hub) typically used in weld-on applications.
B Type (hub using 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 Structure – Once you use a Split Sprocket, you might never want to employ a setscrew mount Agricultural Roller Chain Sprockets Design again. Removal or set up is a breeze. Can be used in virtually all applications. An additional benefit to Black Ace’s split sprockets is usually that the shaft/keyway security is much tighter when compared to a typical setscrew mount.
Split Design Narrow Width – Benefit from the advantages of split style construction and keep the total sprocket width only slightly wider compared to the sprocket tooth thickness.
Hex Bore Split Design – Used in tools that uses hexagon shafts.
Idler Design – Assembled with a long-lasting Black Ball Bearing
