Heavy Series Roller Chains
Heavy series chain uses the same pitch as standard chain but with thicker plates, so it takes higher loads and shock. It suits heavy conveyors, elevators and mining equipment, and fits the same sprockets as standard chain of that pitch.
- Thicker plates for shock loads
- Same sprockets as standard chain
- Suits elevators and heavy conveyors
