Heavy-Duty Roller Chain

Heavy Series Roller Chains are manufactured to ANSI B29.1 Standards but feature thicker side plates. Having thicker side plates not only drastically increases the strength and fatigue resistance of a roller chain, but it also reduces stretching and wear that happens over time. Heavy-duty roller chains are optimal to use in agricultural applications, skid steers, heavy equipment, and any application that you are looking to increase the strength of the chain without having to go up a size.

Note: All of our heavy-duty series roller chains regardless of quality level sereis is supplied with solid-rollers (excluding #25H and #35H)

Split vs. Solid

Solid rollers drastically increase the overall working life of a roller chain because it is the first and primary point of contact between the chain and sprocket. Split rollers have the tendency to deform quickly and cause further wear.
Solid bushings decrease the amount of internal friction on the roller chain and even after long-term use, solid bushings keep their form. This further increases the working life and durability of a chain, and will greatly perform superiorly in medium to high-speed applications.

Quality Levels Available:
Economy Plus heavy roller chains are manufactured in accordance with ANSI B29.1 Standards and feature high tensile strengths, solid rollers, and are useful in light to moderate duty applications.
General Duty Plus heavy roller chains are the best value when it comes to buying heavy-duty roller chain. They typically offer extended performance, solid rollers, solid bushings in select sizes, higher quality material, high-precision components, and are supplied with a good quality lubricant. General Duty Plus heavy roller chains are useful in moderate to heavy-duty applications.
Premier Series heavy duty roller chains are our top tier because they feature solid bushings and solid rollers on all sizes. Each component that goes into the Premier Series heavy duty roller chains are heat treated for maximum hardness, shot peened and manufactured with optimal precision. They are pre-stretched after assembly to reduce or eliminate elongation. They offer the highest strengths, best performance, and longest working life. These chains are useful in applications that require a high strength and precision roller chain for extreme duty applications.

Heavy-Duty Roller Chain Sprockets

Besides roller chain, we can also supply sprockets. When using a sprocket that has less than 30 teeth for heavy roller chain, it is recommended that the sprocket has hardened teeth. All of the sprockets we supply with 30 teeth or less come with hardened teeth as a standard.

Single-Strand Heavy Chain Sprockets

Single strand heavy duty roller chain is compatible with standard sprockets. We keep a full line of ANSI sprockets in stock in a wide range of variations, including taper bushed and QD style.

Multi-Strand Heavy Chain Sprockets

Multi-strand heavy duty roller chain sprockets and standard multi-strand roller chain sprockets are not interchangeable. The reasoning is being that the thicker side plates on the chain will not allow for the roller chain to seat and engage properly with a standard double sprocket. We can supply specially manufactured sprockets for this chain but it will require a 1 - 3 week manufacturing lead time.
