Description & Specifications
CA550HD roller chain is a "heavy duty" version of our standard CA550 chain. The heavy duty chain can hold up to repetitive shock loads much longer than the standard chain. The CA550HD gets the added strength the thicker links plates that's used. Tenisles strength for the CA550 heavy duty is almost 3,000 lbs more than standard CA550 chain.

Features
Thicker Link Plates
The Heavy series chains are enhanced by using thicker link plates. This adds fatigue strength, allowing the chain to withstand higher & repeated shock loads.
Solid Roller
Manufactured with solid cold-forged rollers for smoother contact with the sprocket teeth and to resist distorting under heavy loads.
Pre-Loaded
After assembly, all Nitro chains are pre-loaded to a minimum load required by the industry standard. Pre-loading seats the chain joint that eliminates any initial elongation in a new chain.
Lubrication
Pre-lubricated in a special formulated lubricant through a hot-dipping process. This process is critical to ensure the lubricant penetrates and thoroughly coats the internals of the chain. The special lubricant offers better retention (less spin-out) and improved wear protection over chains that are cold-dipped.
Heat Treated
Advanced heat treatment is applied to achieve optimum hardness for strength and wear resistance.
Shot Peened
To combat fatigue failure from repetitive loads & wear, a compressive stress layer is added through shot peening.
Product Care & Maintenance
Maintenance and lubrication is crucial in the overall performance and life span of roller chain. Proper lubrication will reduce abrasion, chain wear, friction, noise and keep chains running cooler at higher RPM's. You can download the Nitro Roller Chain Care below.
