The ANSI / ASA 50 Single Strand (Simplex) Single Crank Link (Offset Half-Link) (half-link) is designed for odd-pitch length adjustment on ANSI / ASA 50 Single Strand (Simplex) Roller Chains. Conforming to ANSI B29.1 / ASME B29.1M / ISO 606 (10A), this offset link allows addition or removal of a single pitch (15.875 mm (0.625 in / 5/8″)) to obtain ideal chain tension on fixed center-distance drives.
Key Specifications & Benefits
- Fine-Tuned Drive Tensioning: Solves center-distance alignment issues where take-up idlers or sliding motor bases cannot be accommodated.
- Contoured Offset Plates: High-tensile heat-treated alloy steel side plates engineered to absorb cyclic fatigue and evenly distribute bending stresses.
- Matched Dimensions: Precision formed to 15.875 mm (0.625 in / 5/8″) pitch, 9.40 mm (0.375 in / 3/8″) inner width, and 10.16 mm (0.400 in) roller/bushing diameter.
- Hardened Retaining Pin: Supplied complete with heavy-duty pin and cotter fastener matching heavy industrial duty cycles.
Operating Recommendation
When installing offset crank links, ensure operating loads do not exceed the recommended working load limits for ANSI offset link assemblies.
