240-2 roller chain is an ANSI B29.1 standard roller chain with a 3" pitch. #240-2 double row roller is the largest ANSI pitch size chain on the market. Nitro 240-2 chain is manufactured with solid rollers and solid bushings. Our chain is made using high grade carbon steel with precision heat treatment to the plates, pins, rollers and bushings to increase the overall strength.

Solid Bushing & Solid Roller
Manufactured with both solid rollers and solid bushings, which offers far greater wear resistance and longer service life over any chain using split bushings/rollers. See the advantages of using Nitro Chains with solid bushings. over
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.
