AL Series Leaf Chain

AL series leaf chains consist of ANSI standard roller chain plates and pins for light load applications.

| About AL Series Leaf Chain

AL series leaf chains are only consisted of plates and pins from ANSI standard roller chains.

The plates and pin diameter of AL leaf chains are similar to standard roller chains of same pitch.

For example, AL6 uses plates and pin diameter of ANSI 60 roller chain.

AL leaf chains are commonly used for load equipment and light lifting applications.

For corrosive environment, corrosion resistant coating is available.


BL series leaf chains are recommended for heavy duty applications


| Features

  • Heat treatment for improved hardness and strength
  • Shot peening for improved fatigue strength 
  • Pre-stretched to minimize initial stretch
  • Pre-lubricated from the factory
  • Corrosion resistant coating available

| How to select leaf chain for your application

1. Determine the type of leaf chains and service factor from below application table.


Shock LoadApplicationChain TypeChain SpeedService Factor


Smooth Running

Smooth start & stop

Slow operating

Gentle vibration

2. Multiply required working load of your lead chain by above service factor and below safety factor to obtain the tensile strength.

3. Select proper leaf chain with the minimum tensile strength above the value obtained in step 2.  

Working Load x Service Factor x Safety Factor Leaf Chain with Minimum Tensile Strength 

Working load includes attachments weight, inertia force, and impact force.
