Nitro #140-2 cottered roller chain is a high quality, high strength chain that is manufactured to the ANSI B29.1 standards. 140-2C roller chain is a double strand chain that is commonly referred to as duplex cottered chain. Cottered roller chain uses cotter pins on one side, which makes cutting down the chain easier than a riveted roller chain. Our #140-2C cottered roller chain components are always manufactured from the best quality raw materials for strength. The chain components are shot peened & precision heat treated to increase the overall strength, wear resistance, longevity & fatigue resistance. Each 10ft roll of 140-2 cottered chain includes one connecting link.

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.
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.
