The S55 Connecting Link (also known as a master link or joiner link) is designed for quick, secure connection of S55 S-Type Agricultural Chains. Engineered to match original chain strength and specifications (41.40 mm (1.630 in) pitch, 22.23 mm (0.875 in) internal width), ensuring dependable power transmission without creating weak points.

Key Specifications & Benefits

Direct Fit for S55 Chain: Precision-ground pins and side plate maintain pitch integrity (41.40 mm (1.630 in)) and pitch-line geometry.
High Shear Strength: Induction-hardened pins engineered to match the 33.0 kN (7,418 lbf) minimum tensile rating of S55 chains.
Field-Service Ready: Facilitates rapid chain installation, repair, and loop closure in the field with secure spring clip / cotter pin retention.
Corrosion & Wear Resistance: Treated carbon steel construction resists rust and premature pin galling.

Application Note

Essential spare part for maintenance kits on combine harvesters, balers, feed wagons, and agricultural elevator systems using S55 roller chain.
