The Difference Between #40 Roller Chain and #41 Roller Chain

The Difference Between #40 Roller Chain and #41 Roller Chain

Jun 14,2024
#40 Roller Chain VS #41 Roller Chain

Roller chains are essential components in various industrial and mechanical systems, providing a reliable method for transmitting power. Understanding the differences between #40 and #41 roller chains is crucial for selecting the right chain for your specific needs.

Our 40 and 41 roller chains are typically made from high-quality steel, but variations can include nickel-plated or stainless steel options to enhance corrosion resistance.
40 Roller Chain

RS40 Roller Chain:

The #40 roller chain has a pitch of 0.5 inches, a larger roller diameter, and a width between inner plates of 0.312 inches. This makes it more robust and capable of handling higher loads.

RS41 Roller Chain:

The #41 roller chain also has a pitch of 0.5 inches, a smaller roller diameter, and a narrower width of 0.25 inches between inner plates, making it lighter and more suitable for less demanding applications

40 and 41 Roller Chain Performance

Load Capacity and Strength:

The #40 roller chain has a higher tensile strength, making it suitable for heavy-duty applications like industrial machinery and agricultural equipment. The #41 roller chain, with its lower tensile strength, is better suited for lighter loads.

Compatibility with Sprockets:

The difference in roller diameter affects how each chain engages with chain sprockets. The larger rollers of the #40 chain provide better contact and engagement, which can enhance performance and longevity in high-stress applications.

Advantages and Disadvantages


Advantages: Higher strength and durability.
Disadvantages: Bulkier and more expensive.


Advantages: Lighter, more compact, and cost-effective.
Disadvantages: Lower load capacity and limited to lighter applications

Making the Right Choice

When choosing between #40 and #41 roller chains, consider factors such as load requirements, space constraints, cost, and availability of compatible components. For heavy-duty applications, the #40 chain is generally the better choice, while the #41 chain is suitable for lighter, more compact uses​
In summary, while both #40 and #41 roller chains have specific advantages, the right choice depends on your application's requirements. Carefully assess your needs to ensure optimal performance and reliability from your roller chain.
By understanding these differences, you can make an informed decision that ensures your machinery operates efficiently and effectively.
