Adept Cobra S600 Ball Spline Assembly Ball Spline Assembly

Adept Cobra S600 Ball Spline Assembly is a replacement component for the Cobra S600 four‑axis SCARA robot, designed for use in the third and fourth joints of the Adept SCARA system. The assembly forms part of the joint flange interface, employing a ball‑spline arrangement to connect the rotating outer link to the quill shaft. The flange uses a setscrew to fix rotational position on the shaft, and a small steel ball bearing sits behind the setscrew to engage a vertical‑spline groove in the shaft (the bearing is 3.5 mm in diameter and must be kept in place during maintenance). This specific ball spline assembly is sold as a used replacement item described as suitable for the Cobra S600 third and fourth joints and is listed as fitting 32 mm and 16 mm belt configurations. Offered by Next Day Automation, the current listing shows model Cobra S600, item condition Used, price USD 875.00, with 1 unit in stock. In practice, the part supports the precise axial translation and rotational alignment required by the Cobra joint geometry, enabling reliable end‑of‑arm tooling operation in common SCARA applications such as pick‑and‑place, assembly, and machine tending where the Cobra S600 platform is deployed.
