Summary
This guide will discuss the difference between ANSI and ISO roller chains, and help you choose the right chain for your applications.
When selecting roller chains for industrial applications, understanding the standards that govern their design and manufacturing is crucial. Two of the most widely recognized standards for roller chains are ANSI (American National Standards Institute) and ISO (International Organization for Standardization). Both standards define the technical specifications for roller chains used in power transmission systems but differ in dimensions, tolerances, and other key parameters.
In this article, we will explore the key differences between ANSI and ISO roller chains, their respective applications, and the pros and cons of each standard to help you make an informed decision about which roller chain best suits your specific needs.
Cottered roller chains use cotter pins to hold the pins in place, making them more flexible for maintenance. The cotter pin design allows for easier disassembly and reassembly, which can be beneficial in environments where chains need to be adjusted or repaired frequently. They are often preferred in agricultural and construction equipment where ease of maintenance is prioritized over maximum load capacity

Difference Between ANSI Roller Chain and ISO Roller Chain
| Feature | ||
| Measurement System | Uses Inches as the primary unit of measurement | Uses Millimeters as the unit of measurement |
| Chain Dimension and Pitch | Generally in a 1/8-inch pitch size | A 1.5 mm pitch size |
| Chain Tolerance | ANSI standards roller chains have slightly looser tolerance and can have a bit more flexibility in manufacturing. | ISO standards roller chains often more precise in dimensional tolerances, suitable for high-accurate applications. |
Common Application Region | North America | Europe and Asia |
