#40 Roller Chain

This #40 roller chain is manufactured in accordance with American National Standards Institute (ANSI) B29.1 standards and has been manufactured to the same dimensions since the beginning of ANSI/ ASA in 1930. Though dimensionally the exact same we offer three different quality levels of the #40 roller chain that goes above and beyond the standard strength and performance wise.

Economy Plus series #40 roller chain uses heat-treated precision components and feature a solid roller design for improved performance.
General Duty Plus series roller chain is essentially the same except uses a higher-heat treat thus making it better for high-speed and higher load applications.
Premier Series roller chain uses the highest-strength components that have been heat-treated, shot-peened, and hardened to a maximum. They also implement a solid bushing solid roller (SBR) design and use a premium-grade lubricant for the maximum durability, strength, and working life.

We stock a wide range of configurations for #40 roller chain including anti-corrosive, attachment chains, and specialty series.

Standard #40 roller chain includes the most commonly sold carbon-steel 40 chains. We offer these chains in all three of our quality levels and in standard stock length sizes (10ft, 50ft, 100ft, 250ft, and 500ft). We can also supply ANSI Standard #40 roller chain in custom cut to length strands upon request.

Roller chain links consists of connecting links (master links), offset links (half links), and roller links (inner links). #40 connecting links are designed to connect two ends of the chain together, while offset links are made to make length adjustments on the chain, and roller links are made for repairs and length adjustments. We stock a range of 40 roller chain links in all of our quality levels.

Heavy 40 roller chain is designed with thicker side-plates (side-bars), 0.079" VS. 0.059", that 0.020" increase in side plate thickness leads to a chain that has higher strength capacity, better shock-load absorption, and in most circumstances will last longer. Heavy 40H roller chain runs on the exact same sprockets as standard 40 chain (excluding double-single), when upgrading to heavy chain it is imperative to ensure there is enough room to accommodate the new chain type.

Problem solver chains are manufactured for tough-wear applications where a standard roller chain just simply won't hold up or for applications that are difficult to service. For the best problem-solver chain application pairing contact one of our product experts for assistance! We also supply custom made problem solver chains in larger quantities.

Self Lubricating 40 Roller Chain:

When a chain is in an application that is difficult, dangerous, or impossible for proper lubricating we recommend a chain that is self lubricating. The chain is self lubricating by having oil impregnated pins and bushings that slowly release oil as needed.
