Sizing guide for leaf chains


In this article, we will provide a comprehensive sizing guide for leaf chains. Leaf chains are widely used in various industrial applications, providing reliable and efficient power transmission. Understanding the sizing principles is essential for selecting the right leaf chain for your specific needs.

1. What are leaf chains?

Leaf chains are a type of roller chain commonly used in heavy-duty applications such as forklifts, hoists, and conveyors. They consist of interconnected links with cylindrical rollers that allow smooth movement and efficient power transmission.

2. Determining the chain size

When selecting a leaf chain, it is crucial to determine the correct size to ensure optimal performance and longevity. The chain size depends on several factors:

2.1 Pitch

The pitch refers to the distance between the centers of two adjacent pins. It is a critical parameter in sizing leaf chains and is usually measured in inches or millimeters.

2.2 Number of links

The number of links in the chain is determined by the specific application requirements. It affects the overall length of the chain and can be adjusted accordingly.

2.3 Load capacity

The load capacity of the leaf chain is an important consideration, as it determines the maximum weight the chain can support without failure. It depends on factors such as material strength, roller diameter, and lubrication.

3. Factors affecting leaf chain selection

When selecting a leaf chain, various factors should be taken into account:

3.1 Environment

The operating environment, including temperature, humidity, and presence of corrosive substances, can impact the chain’s performance and durability. Choosing the right material and surface treatment is essential for reliable operation.

3.2 Speed

The operational speed of the chain affects its performance and lifespan. Higher speeds may require additional lubrication or specific design considerations to reduce wear and ensure smooth motion.

3.3 Tension

The tension in the chain determines the amount of force it can transmit. It is crucial to calculate the required tension accurately to avoid premature wear or failure.

4. Leaf chain installation and maintenance

Proper installation and maintenance are essential for maximizing the lifespan of leaf chains:

4.1 Installation

Leaf chains should be installed following the manufacturer’s guidelines. Proper tensioning, alignment, and lubrication are crucial for optimal performance and longevity.

4.2 Maintenance

Regular inspection and maintenance are necessary to identify any signs of wear, damage, or improper lubrication. Proper lubrication intervals and methods should be followed to prevent premature wear and failure.


Choosing the right leaf chain size is crucial for achieving optimal performance and reliability in various industrial applications. By considering factors such as pitch, load capacity, and environmental conditions, you can select the ideal leaf chain for your specific needs.
