About 8×8mm Bore 20mm OD×25mm Length Set Screw Flexible
Technical specifications: Material: Aluminum alloy Product Type: Set screw style beam coupling Dimensions: large Bore: 8mm（5/16 inch), Small Bore: 8mm, Outer Diameter: 20mm(25/32 inch), length: 25mm(63/64 inch) Cap Screw: M3-4 Nuber of Screws: 4 ea Angular Misalignment: ≤ 2° Parallel Misalignment: +0.20mm/-0.20mm Rated Torque: 1.0Nm Maximum Torque: 2.0Nm Maximun Rotatonal Speed: 19000RPM Application: It is one-piece metallic flexible coupling for step motor connect, servo applications and also the most common applications are attaching encoders to shafts and motion control for robotics. Notes Note 1: Performance ratings are for guidance only. The user must determine suitability for a particular application. Note 2: Torque ratings for the couplings are based on the physical limitations/failure point of the machined beams. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the machined beams. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the machined beams.
