Standard Roller Chains

Our lineup of standard roller chains include the most common chain sizes and types in the industry. These chains conform to ANSI B29.1 Standards and are manufactured from high-quality carbon steel. For more information or pricing simply contact us or select the subcategories below.

ANSI Single Strand Roller Chains

Single-Strand Roller Chains are also categorized as simplex or are designated with a (-1) after the specific chain size. The "standard" lineup of chains consists of the most commonly used roller chains in the world today. These sizes include # 25 (1/4" pitch) up to #240 (3" pitch). Within each size, we offer different quality levels and options.

ANSI Heavy-Duty Roller Chain

Heavy-Duty roller chains are also commonly referred to as heavy roller chain or heavy-duty roller chain. Something important to note about these chains is that they utilize thicker side-plates than standard chains, this means that single-strand (simplex) heavy roller chain will run on the same sprockets as standard (excluding double-single type) but double strand (duplex) heavy roller chains require specially manufactured sprockets due to the need of increased width between the sets of teeth.
