81x chain

81X chain features a 2.609" pitch and is categorized as a steel bushed roller chain within the engineer class of chains. It is commonly called an 81X conveyor chain due to the straight side-bar design and common usage within conveying applications. This chain is commonly found in the lumber and forestry industry and is available with upgrades such as "chrome pins" or heavier-duty sidebars. Because of its high strength and effective design, this chain can be found in applications worldwide, such as lumber, agriculture, mills, grain handling, and many more drive and conveying applications.

81X Chain Features

81x chain rivets
Though dimensionally equivalent to other chains, our 81X chain is manufactured with quad-staked rivets. The main benefit is that the chain can withstand higher shock loads and side-loading without falling apart.

81x chain bushings
Utilizing a solid bushing & solid roller configuration with 81X conveyor chains drastically improves performance and wear life compared to split bushing or split roller configurations.

81x chain material
All of our 81X chains are manufactured using superior alloys, with each component being heat-treated to provide excellent wear life and extreme durability.

81X Conveyor Chain Maintenance

Maintaining an 81X chain is vital to ensure you get the most out of your chain. We stock a variety of tools and accessories to go along with your 81X chain.
81X Chain Breaker:

The most popular 81X accessory we sell is our Made in USA 81X Chain Breaker; it effortlessly breaks the quad-staked rivets of your chain and makes it easy to re-size the chain or make repairs.
81X Chain Puller:

The Made in USA Cable Operated Chain Puller we supply uses a heavy-duty ratcheting system to take tension off of the chain when breaking it or making repairs.
Chain Guide:
81x chain guide

The Chain guide creates an easy-gliding, low-friction surface for the 81X chain to run on. Typically, it is made from UHMW material and is channel style like the above photo. Using a guide drastically increases the life of a chain by eliminating friction and metal-on-metal contact.
Chain Lube:
81x chain lube

Keeping your 81X chain lubricated can also play an important role in extending the overall chain life; it also promotes a smoother operating chain by reducing internal friction. We supply roller chain lube in spray cans or 5-gallon buckets.
