Metric roller chains are an essential component in various industrial applications, and they are known for their efficiency, durability, and reliability. Unlike ANSI roller chains, which use inch-based measurements, metric roller chains are measured in millimeters, making them ideal for machinery and components manufactured in Europe. Metric roller chains are designed to meet ISO and British Standard specifications, ensuring compatibility with European-manufactured equipment.
We manufacture metric roller chains to meet ISO and British Standards, our standard roller chains be used interchangeably with sprockets from other vendors, simplifying maintenance, and enhancing equipment compatibility.
Metric Roller Chain Pitch Size
Types of Metric Roller Chain
Metric Roller Chain Dimension
✔ Pitch (P):
Distance between roller centers.
✔ Inner Width (b1):
Distance between inner plates.
✔ Roller Diameter (d1):
Diameter of the rollers.
✔ Plate Height (h2) and Thickness (T):
Dimensions of the chain plates.
✔ Pin Diameter (d2)
The diameter of the connecting pins.
