Description & Specifications
40-2 roller chain is a double row ANSI standard roller chain. Nitro #40 double roller chain is an high quality roller chain that is manufactured for strength and longevity. Our double strand roller chains are manufactured from a high quality carbon steel. Each individual chain component is heat treated to increase the overall strength of the chain. Plates and rollers are shot peened to improve the fatigue resistance and help prevent stress fractures.

Features
Solid Roller
Manufactured with one-piece solid cold forged rollers that offer smoother contact with sprocket teeth and will not distort under heavy loads.
Pre-Loaded
After assembly, all chains are pre-loaded to seat the chain components and eliminates any initial elongation on a new chain.
Lubrication
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.
Heat Treated
Advanced computer controlled heat treatment is applied to all critical parts to maximize the strength and wear resistance.
Shot Peened
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.
