The A290-7021-X435, manufactured by FANUC, is a structural link rod within the Alpha Series. It is designed explicitly for S-110R and S-110RC robots, and it accommodates RJ3, RJ3i, R30iB, and R30iB+ controller types. This component is integral to the wrist-to-forearm joint assembly in robotic applications.

Constructed from hardened CrMo steel, this link rod is treated with an electroless nickel plating to improve its corrosion resistance. The surface finish is complemented by a zinc-phosphate coating, enhancing its durability further. The rod can withstand a static axial load of 5 kN (1,100 lbf) and a dynamic radial load of 1.55 kN (350 lbf) when operating at 100 rpm.

Designed to function effectively within a temperature range from -10°C to +80°C, the A290-7021-X435 meets the strict dimensional requirements with a length tolerance of ±0.05mm for every 100mm. The part features ingress protection rated equivalent to IP65, ensuring adequate defense against dust and water. The straightness specification is maintained within ≤ 0.1mm/m, reflecting precise engineering standards for optimal performance.
