Roller Chains with Straight Side Plates (B Series)
As a precision-engineered power transmission component adhering to ISO/R 606 (British Standard) specifications, the B Series Roller Chains with Straight Side Plates are designed to deliver exceptional stability, durability, and universal compatibility in medium-load industrial applications. Distinguished by its optimized straight side plate geometry and rigorous manufacturing tolerances, this series excels in scenarios requiring reliable meshing performance, easy maintenance, and adherence to European and Asian industrial standards—making it a preferred choice for mechanical transmission systems across global manufacturing, automotive, and light industrial sectors.
Core Advantages: B Series Straight Side Plate Design & Precision Engineering
The defining feature of the B Series is its precision-machined straight side plates, engineered to ISO/R 606 standards with tighter flatness tolerances (≤0.01mm) compared to conventional chains. Crafted from high-grade carbon steel (1045) or alloy steel (20Mn2), the straight side plates ensure uniform load distribution across each link, eliminating stress concentration and enabling smooth, vibration-free meshing with B-series sprockets. This design is particularly suited for medium-speed operations (up to 380 rpm), where transmission accuracy and low noise output are critical.
Unlike A-series chains, the B Series features a slightly smaller pitch diameter and optimized roller-bushing fit, enhancing wear resistance and extending service life. Rollers and pins undergo advanced carburizing, quenching, and tempering processes, achieving a surface hardness of HRC 58-62 for superior wear performance, while the core maintains toughness (HRC 38-42) to resist impact deformation. The straight side plates are precision-stamped and heat-treated to maintain structural integrity, supporting working load capacities from 7kN to 105kN across single-strand, double-strand, and triple-strand configurations.
Versatility and cost-effectiveness are further enhanced by standardized design and multiple connection options. The B Series supports both cottered (permanent) and spring clip (quick-adjust) connections, enabling on-site assembly and maintenance without specialized tools. Optional surface treatments—including black oxide, zinc plating, and nickel plating—provide targeted corrosion resistance for humid, dusty, or moderately corrosive environments. Its compliance with ISO/R 606 standards ensures universal compatibility with B-series sprockets and existing European/Asian equipment, reducing replacement costs and retrofit complexity.
Structural Excellence & Operational Resilience
Engineered for consistent performance in everyday industrial conditions, the B Series maintains lateral stability through its straight side plate design, preventing chain deflection and ensuring precise alignment with sprockets even in long-distance transmission systems. The optimized roller-bushing assembly minimizes contact friction, reducing energy loss and operating noise (≤58dB), while the heat-treated components withstand temperature fluctuations from -25℃ to 120℃—adapting to both indoor industrial environments and mild outdoor applications.
Safety and maintainability are integrated into every design detail. The smooth, straight edges of the side plates minimize debris accumulation and reduce the risk of jamming, while the predictable wear pattern allows for proactive maintenance scheduling. The chain’s standardized dimensions and connection types simplify replacement of links or components, ensuring minimal operational interruptions and lowering overall maintenance costs.
