Roller chains encompass chains conforming to DIN 8187, DIN 8188, and DIN 8181 standards. Due to their widespread use, these chains and gears are standardized to align with various international standards.

• DIN 8187 corresponds to the ISO 606 European (BS) Standard (e.g., 08 B, 10 B).
• DIN 8188 corresponds to the ISO 606 American (ANSI) Standard (e.g., 08 A, 10 A).

Roller chains are utilized in machine and plant construction not only as drive and gear chains but also in specialized configurations with various attachments for lantern gears, lifting systems, conveyor systems, and transfer and transport systems. Roller chains with appropriate attachments can perform specialized functions, making them versatile for a wide range of applications.
