ENGINEERING CLASS CHAIN SPROCKETS


Product Guide

Black Ace Engineering Class Sprockets are manufactured with the highest integrity. You will find value, as these sprockets are flame-cut and machined with the highest precision available on the market.

  • ASME Standard Torch Profiles – Elongated Root Design promotes a self-cleaning effect of the root to keep your demanding applications moving.
  • A – B – C Hub Types
    • A Type (no hub) typically used 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 on both sides) used in applications where B Type is not wide enough to withstand torques produced by drive.
  • Split Style Construction – Once you use a Split Sprocket, you may never want to use a setscrew mount style again. Removal or installation is a breeze. Can be used in virtually all applications. An additional benefit to Black Ace’s split sprockets is that the shaft/keyway security is much tighter than a typical setscrew mount.
  • Hardening Available – Flame hardening of sprockets is available as an option.
