Precision roller chains are the foundation of reliable power transmission systems across manufacturing, material handling, and processing industries.

As an industry-leading roller chain supplier, MAXCO Chain offers high-strength ANSI and British Standard roller chains engineered for durability, precision, and long service life.

Our precision roller chain is engineered to meet or exceed ANSI B29.1 standards or ISO 606 B, BS 228, and DIN 8187 European standards and to deliver consistent performance in conveyance applications, drives, and industrial machinery where dependability is essential.

We supply a full range of sizes and configurations — from standard chains to extra capacity, corrosion-resistant, and low maintenance varieties.

Roller Chain Standards

All MAXCO industrial roller chains are manufactured to meet American National Standards Institute (ANSI) B29.1 or British Standard ISO 606 B.

These standards define pitch, roller diameter, width and plate thickness, which ensures interchangeability across brands and applications.

Each roller chain size corresponds to precise engineering standards for pitch and load capacity. Selecting the correct pitch and size ensures smooth operation, reduced wear and proper sprocket engagement.

Specs & Dimensions

Choosing the correct roller chain depends on understanding key technical specifications, including pitch, roller diameter, and tensile strength.

The roller chain pitch chart above helps identify the ideal chain size for your application — whether for conveyors, drive systems, or power transmission equipment.

Specification Description
Standard Pitch Range 0.25” to 3.00”
Chain Series Single-strand, multi-strand, double-pitch
Materials Carbon steel, stainless steel and coated options offering corrosion resistance.
Lubrication Options Pre-lubricated and self-lubricating options.
Typical Applications Conveyors, industrial drives, packaging, and automation systems

All MAXCO Chain industrial roller chains are precision machined and heat-treated for strength, flexibility, and long service life. This makes them ideal for high-speed or continuous-duty operations.

FAQs: Choosing Roller Chains

Q: What is a roller chain?

A: Roller chain is a type of mechanical chain manufactured to either ANSI B29.1 or ISO 606 B, BS 228, and DIN 8187 European standards. The standards ensure uniform pitch, roller size, and tensile strength for interchangeability across manufacturers.

Q: How do I choose the correct roller chain size?

A: Determine load and speed – Identify the power to transmit and shaft speeds to select the appropriate strength and pitch.

Select the chain type – Choose standard, heavy-duty, or corrosion-resistant chains based on environmental and duty conditions.

Match pitch and sprockets – Ensure the chain pitch, roller diameter, and width are compatible with sprockets for reliable operation.

Check tensile strength – Verify the chain’s minimum tensile rating exceeds the maximum load, including shock and peak loads.

Consider length and tension – Calculate the correct chain length for proper tension and smooth operation.

Q: What’s the difference between industrial roller chains and other chain types?

A: Industrial roller chains are specifically engineered for efficient, high-strength power transmission, while other chain types are typically designed for material handling, lifting, or specialized functions.

Q: Does MAXCO Chain offer custom roller chain solutions?

A: Yes. We provide custom cut-to-length roller chains, special attachments, and bulk supply options for our customers. MAXCO Chain offers a full range of sizes and configurations — including standard chains, extra capacity, corrosion-resistant, and low maintenance varieties.
