The S55 Single Crank Link (also known as an offset link or half-link) allows length adjustment of S55 Agricultural Chains by adding or subtracting an odd number of pitches (1 pitch = 41.40 mm (1.630 in)). Crucial for achieving precise chain tension on fixed-center agricultural drives and conveyors.
Key Specifications & Benefits
- Accurate Chain Tensioning: Enables single-pitch adjustments to compensate for fixed center-distance sprockets and chain wear.
- Heavy-Duty Contoured Side Plates: Formed from high-tensile alloy steel to distribute torsional loading evenly across the offset geometry.
- Exact OEM Compatibility: Perfectly matches S55 chain dimensions (41.40 mm (1.630 in) pitch, 17.78 mm (0.700 in) roller diameter, 22.23 mm (0.875 in) inner width).
- Case-Hardened Pin: Comes complete with heavy-duty pin and cotter/fastener designed for severe shock loads.
Operating Recommendation
Recommended for use in agricultural drives requiring intermediate chain tensioning where idler sprockets or movable take-up frames cannot be fitted.
