Nitro® ANSI Standard Roller Chains

ANSI standard roller chains are the most widely used power transmission chains in the USA. A true powerhouse in precision & quality, the Nitro ANSI chains are built to handle a broad range of applications across many industries. Rigorous quality standards ensures every chain consistently adheres to our requirements for strength and dependability. ANSI chains come in a several options including multiple strands for applications with higher horsepower requirements.

Nitro® roller chains are designed, tested and built behind 40+ years of experience in manufacturing of roller chains. We want the best put into every link.

ANSI Roller Chain Sizes

There are a total of 14 sizes that make up the entire line of ANSI chains. You can view all ANSI chain sizes charts to help identify your chain size.

ANSI Riveted vs Cottered Roller Chains

Chains are manufactured with two different pin constructions, which are referred to as riveted or cottered. Dimensionally both chains are the exact same other than the overall width where the cottered chain is slightly wider. The benefit with cottered is that it eliminates the need of grinding down the pin heads to disassemble the chain. This is especially beneficial when working with larger pitch roller chain.

There are certain situations where cottered chain is not recommend due to higher chances of cotter pins breaking or falling out. As an example, we recommend not using cottered chain in applications with severe vibrations or where material may contact the chain.

Standard Vs Heavy Duty ANSI Roller Chain

Standard roller chain and heavy duty roller chains mostly have the same dimensions. The main difference is that the heavy roller chains are produced with thicker inner & outer link plates. By using thicker plates, this improves the heavy duty chains working load strength and fatigue resistance. This makes the heavy duty roller chain a better choice for drives with moderate shock loads and/or frequent starting and stopping. Standard roller chain are best suited for smoother running drives that have lighter loads.

Advantage Of Nitro® ANSI Roller Chain

Product quality is one of the founding principals that our company was built around. We conduct ongoing research to continue evolving our ANSI roller chains into industry leading quality. In 2021, we developed our second generation ANSI chains that have improved features for better protection against wear. Quality research never stops! We value the trust that customers put into our products to power their machines.

Second Generation ANSI Chain Features

Solid Rollers
Solid Bushings
Pre-Lubricated With Special Blend
Improved Shot Peening

These features are standard with all Nitro's ANSI chain. The competition requires an "upgrade" for these features at premium prices.
