ANSI Leaf Chains


USA Roller Chain has the best prices and quality available on leaf chains with our premium and economy lines. You’ll find the right product whether you need a leaf chain for forklifts, machine tools, rolling door counter balances, or any other application. We vet all leaf chain suppliers and products for the highest-quality, most durable leaf chains. All of our leaf chains are heavy duty with tensile strengths that vary from thousands to tens of thousands of pounds. Our store features two types of leaf chain, the AL-Series for lighter lifting, and the BL Series for more heavy-duty work. Additionally, our leaf chains meet both ANSI and ASME standards.

When you buy leaf chains from USA Roller Chain, you won’t have to reorder for a good while. We have confidence in our products. If you’re not sure what chain you need to reorder for your machine, please don’t hesitate to give us a call. We get calls from customers regarding this issue all the time, and we’re happy to help.

Identifying leaf chain is a simple task that can save you from getting the wrong product. In the below video we demonstrate exactly what all is needed for proper leaf chain measurement. For more information or assistance please contact us and we will be happy to assist you.

It is important to inspect your leaf chains on a regular basis to prevent catastrophic failure that can result in equipment and person damage. The chart below indicates several common wear and protocols for your leaf chain.
Problem Possible Cause Solution
Circumferential Wear of Plate
Wear Replace the chain if wear is or exceeds 5% of original side-plate height.
Oblique Wear of Plate and Pin Head
Misalignment of Guide or Pulleys Re-Align Machine
Stiff Link
Dust or foreign substances are contained in a bending portion
corrosion and rust
Bent Pin
Wash Chain and Lubricate
Replace the Chain
Replace the Chain
Abnormal Protrusion or Rotation of Pin Head

Excessive Tension by Overload or Insufficient Lubrication Replace the chain, lubricate, and eliminate overload
Wear Elongation
This occurs with normal wear over time or can be the result of a permanent deformation due to overload. Replace the chain when its length becomes 1.03L.
Note: Wear elongation of a chain will lower its tensile strength (wear elongation of 3% lowers the tensile strength by 18%)
The wear life of the chain can be increased by using lubrication.
Cracked Plate (1) where the crack from hole of a link plate in the direction perpendicular to tension direction.
Load exceeding the allowable tension of chain Replace the chain with a chain of higher maximum allowable tension, or lower the load of dynamic shock load.
Cracked Plate (2) where the crack takes place in an oblique direction against tension direction
Heavy rust or corrosion to a corrosive material. Replace the chain and protect it from corrosive circumstances.
Broken Plate by High Tension
Overload Replace the chain and eliminate the cause of overload.
Enlarged plate hole
Overload Replace the chain and eliminate the cause of overload.
Corrosion of pit
Corrosive Circumstances Replace the chain, and protect from corrosive circumstances
Wear of Connecting Pin
Normal Wear Replace the Worn Component

We offer a selection of leaf chain accessories including lubrication, leaf chain breakers, and leaf chain connecting links
Leaf Chain Breakers
At USA Roller Chain we supply leaf chain breakers to a range of customers and offer two different styles. For more information or quotes please contact us.
The Hand-Held Breaker:

This hand-held unit is easy to use, made from high-grade tool steel, and completely presses the pins through the chain for seamless and easy disassembly.
Stationary Leaf Chain Breaker:

This German manufactured stationary leaf chain breaker is made for all-day every-day leaf chain breaking. It's supplied with ANSI die sets for almost every leaf chain size out there!
Leaf Chain Lubricant

Lubrication is essential to leaf chain operation and extending the life of the leaf chain. We supply a broad range of chain lubricants for any application.
Leaf Chain Connecting Links

Connecting links are also commonly called master links, they are manufactured for connecting two ends of the chain together.
