Hardened High-Strength Pins - ![]()
One of the most stressed components in a roller chain is the pins. Of course, this translates over to the connecting link of a chain. Here at DUROCHAIN, each pin in our connecting links undergoes a specific hardening process to improve wear life, strength, and fatigue resistance.
- Quad-Staked Rivets -
![]()
This link is equipped with high-hold quad-staked rivets instead of the standard dual-stake rivets used by other manufacturers. This improves the links ability to withstand shock loads and side thrust. The superior rivet ensures that the link is held together with the utmost capacity possible, giving it more versatile capabilities than its predecessors.
- Unique Sideplates -
![]()
Precision made from steel alloy and hardened to an optimal HRC; our unique side plates provide the highest shock load absorption and most extended wear life! The design adds additional material to the plate while maintaining the dimensional requirements of the ISO, BS, and DIN Standards. These side plates add strength and wear life to their accompanied chain assembly compared to the standard side plates used by other tier-one chains.- High-Strength Cotter -
![]()
With a cottered connecting link, the cotter keys are what hold the link together. Our DUROCHAIN cottered connecting links utilize premium high-strength cotter keys to ensure strength and prevent premature link failure due to a cotter failure.
- Superior Plate Hole Preparation -

Regarding the actual holes in the plates, our superior set of processes (precision piercing, shaving, and ball drifting) make our links easy to install and uninstall. Additionally, this provides the smoothest and best pin-to-plate contact possible.
