ANSI Standard Torch Profiles
A – B – C Hub Types
A Type (no hub) typically found in weld-on applications.
B Type (hub on one side) used in applications where clearance width is narrow. More economical than C Type.
C Type (hub upon both sides) used in applications where B Type isn’t wide enough to withstand torques made by drive.
Split Style Construction – Once you use a Split Sprocket, you might never want to employ a setscrew mount design again. Removal or installation is a breeze. May be used in virtually all applications. Another advantage to Dark Ace’s split sprockets is definitely that the shaft/keyway protection is much tighter when compared to a typical setscrew mount.
sprockets hardening Offered – Flame hardening of sprockets is available as a choice.
