Technically The Best For Two Strong Reasons

Options And Add-Ons

1 Through Heat Treating

Where not standard through heat treated sidebars barrels or rivets are an excellent option to increase chain life. For maximum chain life in severe applications including heavy impact loading and high-speed applications or abrasive conditions specific heat treating may be required.

SIDEBAR Heat-Treated 32-36 Rc
BARRELS Heat-Treated 32-36Rc or Induction Hardened 44-50 Rc
RIVETS Heat-Treated 32-36Rc or Induction Hardened 44-50 Rc

WEAR:In a non-abrasive environment Heat-Treated and/or Induction Hardened chain may have a greater working life expectancy up to 50% longer than non heat-treated.

IMPACT AND STRENGTH: Through Heat-Treated chain will improve impact resistance strength and ultimate strength.

2 Induction Hardening

Where not standard induction hardening can be added to specific components to greatly increase chain life.

INDUCTION-HARDENED PINS: All Mac mill chain comes standard with through Heat-Treated rivets. All Mac mill chain with a 1″ rivet diameter and larger comes standard with an additional induction hardening.

All Mac Drag Chain with a ¾″ and ⅞″ diameter rivet comes standard with zone induction hardening. All Mac Drag Chain with a 1″ diameter rivet comes standard with through heat treating.

SIDEBAR Heat-Treated 32-36 Rc
BARRELS Heat-Treated 32-36Rc or Induction Hardened 44-50 Rc
RIVETS Heat-Treated 32-36Rc or Induction Hardened 44-50 Rc

WEAR:In a non-abrasive environment Heat-Treated and/or Induction Hardened chain may have a greater working life expectancy up to 50 % longer than non heat-treated.

3 Pre-Greasing

Factory pregreasing with premium polymer grease is an excellent way to extend the life of welded steel chain. Pregreasing will greatly reduce initial break in wear increasing overall chain life by 25% or more.

4 Double-Locking

Double locking rivets is the process of welding the rivet head and rivet end to the sidebars locking the rivet in place. This reduces possible rivet and sidebar hole wear that can lead to chain elongation in heavy load or severe applications.
