double pitch

Black Ace Double Pitch Roller Chain Sprockets are manufactured with the highest integrity. You will recognize value, as these sprockets are flame-cut and machined with the highest precision available on the market.

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