ANSI Standard Torch Profiles
A – B – C Hub Types
A SORT (no hub) typically used in weld-on applications.
B Type (hub on one side) found in applications where clearance width is narrow. Less expensive than C Type.
C Type (hub upon both sides) used in applications where B Type isn’t wide enough to withstand torques produced by drive.
Split Style Building – Once you utilize a Split Sprocket, you might never want to employ a setscrew mount design again. Removal or set up is a breeze. Can be used in practically all applications. Another advantage to Dark 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 definitely available as an option.
