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
CorrosiveCircumstances
Replace the chain, and protect from corrosivecircumstances
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.
