The 16B-2 Single Crank Link For British Standard Series Chain (offset half-link) allows precise length adjustments on 16B Double Strand (Duplex) British Standard Chains by adding or subtracting an odd number of pitches (1 pitch = 25.40 mm (1.000 in / 1″)). Conforming to BS 228 / ISO 606 (16B) / DIN 8187, it provides the ideal solution for fixed center-distance drives requiring fine chain tensioning.
Key Technical Specifications & Advantages
- Accurate Chain Tensioning: Solves center-distance alignment challenges where idler sprockets or adjustable take-up frames cannot be installed.
- Contoured Offset Link Plates: Formed from high-tensile heat-treated alloy steel to distribute stress evenly across the crank offset geometry.
- Matched Precision Dimensions: Formed to exact 25.40 mm (1.000 in / 1″) pitch, 17.02 mm (0.670 in) inner width, and 15.88 mm (0.625 in) roller/bushing diameter.
- Heavy-Duty Hardened Pin: Supplied complete with precision-ground pin and secure fastener clip.
Operating Recommendation
Designed for intermediate chain tension adjustment on British Standard conveyor and drive installations.
