The 12B-1 Single Crank Link For Stainless Steel Chain (304 Grade) (offset half-link) allows precision single-pitch (19.05 mm (0.750 in / 3/4″)) length adjustments on British Standard 12B Stainless Steel Single Strand (Simplex) Roller Chains. Built from corrosion-resistant AISI 304 stainless steel in compliance with BS 228 / ISO 606 (12B-SS) / DIN 8187, it provides the ideal solution for fixed center-distance conveyors requiring fine chain tensioning.
Key Technical Specifications & Advantages
- Precision Chain Tensioning: Enables adding or subtracting an odd number of pitches (19.05 mm (0.750 in / 3/4″)) to eliminate chain slack on fixed center conveyors where take-up frames cannot be installed.
- All-Stainless Steel Construction: Formed entirely from AISI 304 stainless steel side plates, hardened pin, and fastener clip.
- Hygienic & Corrosion Proof: Fully resistant to corrosion, oxidation, and chemical washdowns across pharmaceutical and food handling environments.
- Matched Dimensions: Precision formed to 19.05 mm (0.750 in / 3/4″) pitch, 11.68 mm (0.460 in) inner width, and 12.07 mm (0.475 in) roller/bushing diameter.
Operating Recommendation
Recommended for intermediate tension adjustments in food conveyor, packaging line, and washdown environments.
