Types Of Roller Chain
Roller chains are one of the most commonly used power transmission chains in industrial settings. However, there are several different roller chains, each designed for a specific purpose. The most popular varieties include standard, heavy-duty, double-pitch, and leaf roller chains.
Knowing the differences between these types is essential for choosing the right roller chain for your particular application.
Standard Roller Chains
The most widely used type of roller chain, typically conforming to ANSI Roller Chain and Metric Roller Chain.
Commonly used in general-purpose applications such as conveyors, elevators, and packaging equipment.
A stronger and thicker version of the standard roller chain, designed for higher loads and harsher environments.
Thicker plates and stronger pins to withstand higher loads.
Often heat-treated to improve resistance against wear and fatigue.
Ideal for heavy machinery in industries like construction, mining, and agriculture where high tension and heavy loads are involved.
Similar to standard roller chains but with double the pitch (distance between pins), making them more economical for long-distance conveying.
Fewer components, making them lighter and more cost-effective.
Reduced noise and wear due to fewer chain links.
Suitable for light to medium load applications such as agricultural equipment, conveyors, and packaging systems.
Hollow Pin Roller Chain
Roller chains featuring hollow pins, which allow for easy attachment of cross rods, cleats, or other accessories.
Versatile due to the option of adding attachments without removing the chain.
Hollow pins reduce overall chain weight while maintaining strength.
Used in conveyors, material handling, and food processing lines where customized attachments are required.
Leaf chains are typically used in lift and hoist applications due to their high tensile strength.
Composed of stacked link plates instead of rollers.
Designed for tension-heavy applications.
Primarily used in forklifts, cranes, and lifting mechanisms, where the chain must handle extreme vertical loads.
