Diamond roller chains connect shafts and transfer motion between sprockets in industrial machinery. They appear in conveyors, production lines and processing equipment, where the roller design supports steady operation. MR Industrial Accessories LLC supplies these chains and assists with choosing the correct configuration for your application.
The ASME/ANSI code tells you the main characteristics. The first number is the pitch; the suffix after the hyphen is the strand count. A chain marked 25-2 has pitch 25 and two strands, while 35-6 has pitch 35 and six strands. Larger pitch numbers mean a bigger, stronger chain. Suffixes like -2, -3 or -4 indicate multiple strands, used when you need more transmission capacity in a limited space. Reading the code this way helps you identify a replacement quickly.
These chains are common in food processing, metallurgy, cement and logistics. They drive material conveyors, packaging machines, bottling equipment and plant transmission systems, and they also serve in agricultural harvesters and processing equipment. With the right lubricant and sealing, they handle dust, humidity and moderate temperatures.
Selection depends on pitch, strand count, required length and lubrication type. Check sprocket alignment and tension to prevent early wear. Use the lubricant specified for your speed and load. In dirty environments, consider sealed chains or special lubrication. Careful assembly extends the life of the drive and reduces unplanned downtime.
Roller chains built to the ASME/ANSI standard are interchangeable among manufacturers that follow the same standard. A Diamond chain can replace another with a similar designation and pitch if dimensions and load capacity match. When replacing, compare pitch, strand count and end fittings. The original chain code is the best reference for finding an equivalent.
To request a Diamond roller chain, send the code or your equipment details through WhatsApp or email. The team replies promptly, quotes the exact reference and helps you install it correctly.

Frequently asked questions
- What does the suffix -2, -3 mean on a roller chain?
- The numeric suffix indicates the number of strands. For example, -2 is double strand, -3 triple, and so on. Multiple-strand chains transmit more power without increasing the pitch.
- How do I know what chain pitch I need for my machine?
- The pitch is set by the sprocket design. If you are replacing an existing chain, the code stamped on the plate or on the old chain gives you the pitch. For a new transmission, contact us with the load and speed data.
- Are Diamond chains compatible with other brands?
- Yes, roller chains under the ASME/ANSI standard are interchangeable between manufacturers that follow the same standard. Verify pitch, number of strands and dimensions. If you have a code from another brand, we can identify the equivalent.
