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

Quad-Staked Rivets

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.

Solid Bushings & Solid Rollers

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.

Material

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.

High Strength 81X Roller Chain

Some applications may require a stronger version of 81X series chains. Below is the strength compared to the various options for a stronger 81X chain. Note that all of these chains will operate on the same sprockets.
81x chain comparison
81XH Chain - 9,000 LBS Stronger
81XHH (XHD) Chain - 18,000 LBS Stronger
We also stock 81X chains with chrome-plated pins for specific applications.

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:
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:
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.
