Summary:
This document provides technical specifications for the HS-880 BO series side flexing plastic chains, including material composition, mechanical load capacity, and detailed dimensional parameters. The chain plates are made from POM variants, with pins from cold rolled austenitic stainless steel, ensuring durability and flexibility. The working load is specified at standard temperature (21°C). Dimensions are given in both metric and imperial units for clarity. Sprocket dimensions and types are also outlined for compatibility and application guidance.

Critical Information:
- Ensure working load does not exceed 1680 N at 21°C.
- Use specified materials for optimal performance.
- Adhere to dimensional tolerances for sprocket and chain compatibility.
- Reverse radius and weight parameters are essential for installation and operational planning.
