Our B Series Short Pitch Precision Roller Chains are manufactured according to international ISO standards and are widely used in industrial power transmission systems. Available in a full range of ISO chain numbers, these precision-engineered roller chains provide reliable power transfer, high tensile strength, excellent wear resistance, and long service life in demanding industrial environments.
As a professional industrial chain manufacturer with years of design, development, and production experience, we offer a comprehensive range of transmission chains, conveyor chains, agricultural chains, engineering chains, and customized chain solutions for global customers.
Manufactured according to ISO standards to ensure dimensional accuracy and interchangeability.
High-quality alloy steel components combined with advanced heat treatment processes provide extended service life.
Designed for heavy-duty power transmission applications with excellent load-bearing capacity.
Precision machining reduces vibration, noise, and power loss during operation.
Available in various ISO chain numbers, including:
