These B Series Short Pitch Precision Roller Chains are engineered to DIN/ISO standards, available in Simplex, Duplex, and Triplex configurations to suit diverse power transmission needs. Each chain is characterized by its specific pitch, ranging from 6.000 mm to 114.300 mm, alongside defined roller diameters and plate thicknesses. Key specifications include ultimate and average tensile strength, and weight per meter, varying across the range. With precise dimensions for pin diameter, pin length, and inner plate depth, these chains offer reliable performance for industrial applications requiring robust power transfer.
