ANSI Standard Torch Profiles
A – B – C Hub Types
A Type (no hub) typically used in weld-on applications.
B Type (hub using one side) used in applications where clearance width is narrow. More economical than C Type.
C Type (hub on both sides) found in applications where B Type is not wide enough to withstand torques made by drive.
Split Style Structure – Once you use a Split Sprocket, you may never want to employ a setscrew mount style again. Removal or installation is a breeze. May be used in practically all applications. An additional benefit to Black Ace’s split sprockets is that the shaft/keyway security is much tighter when compared to a typical setscrew mount.
Hardening Offered – Flame hardening of sprockets is available as a choice.
