Nitro 140H roller chain is a heavy duty, high strength ANSI roller chain. Our 140H roller chain is made with thicker link plates to improve the strength & durability. Heavy duty roller chain is able to withstand more demanding industrial & agricultural applications for longer periods of time over standard ANSI roller chains. 140H roller chain can be used on the sprockets as 140 roller chain, so you can easily upgrade to our 140H chain. We also offer extra 140H connecting links & 140H offset links.

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.
Manufactured with solid cold-forged rollers for smoother contact with the sprocket teeth and to resist distorting under heavy loads.
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.
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.
Advanced heat treatment is applied to achieve optimum hardness for strength and wear resistance.
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.
