A Type (no hub) typically used in weld-on applications.
B Type (hub using one side) used in applications where clearance width is narrow. Routinely have two (2) setscrews on the hub to Agricultural Roller Chain Sprockets fasten the sprocket to shaft and keyway.

Hex Bore Split Design – Used in products that uses hexagon shafts.
Idler Style – Assembled with a long-lasting Black Ball Bearing
