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.
- Unique Rivets -

On a connecting link, these unique rivets provide superior holding power and high side load capacity. Coupled with a high-grade spring clip for retaining on the opposing side, our connecting links are designed to withstand demanding applications.
Our high-quality spring clips are precision made from the best raw steel material and heat-treated for added strength. The result is a high-hold spring clip that prevents unwanted clip[ failure that would result in the link failing.
- 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.
- 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.
