Nitro 80H-2 roller chain is heavy duty version of our 80-2 standard roller chain. The 80H-2 heavy double roller chain used thicker link plates to increase its overall strength. Our 80H-2 double heavy chain is perfect for machines that have moderate shock loads.

Manufactured with one-piece solid cold forged rollers that offer smoother contact with sprocket teeth and will not distort under heavy loads.
After assembly, all chains are pre-loaded to seat the chain components and eliminates any initial elongation on a new chain.
Thicker Link Plates
Heavy series chains are built with thicker link plates over the line of standard roller chain. This helps increase fatigue resistance, allowing the chain withstand higher and repetitive shock loads.
Pre-lubricated in a special formulated lubricant through a hot-dipping process. This process ensures the lubricant penetrates and evenly coats the entire chain & chain joints. This results in better lubricant retention (less spin-out) that offers better wear resistance and improved service life over cold-dipped chains.
Advanced computer controlled heat treatment is applied to all critical parts to maximize the strength and wear resistance.
Parts are shot peened to add better fatigue resistance and helps prevents cracking from higher loads and wear from operation.
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.
