Duplex Roller Chains (B Series) are engineered for higher power transmission capability, offering superior mechanical reliability and operational integrity in heavy-duty machinery. These double-strand chains are built to DIN 8187 & ISO 606 B-series standards, ensuring synchronized movement and excellent vibration resistance across high-torque industrial drives.
For lighter duty power transmission, see our Simplex Roller Chains (single-strand), or for extreme load requirements, view our Triplex Roller Chains (triple-strand) collection.
