Screw-type bellow coupling specifications vary, but common parameters include bore diameter (3-28 mm), outer diameter (16-40 mm), torque capacity (0.5-12 Nm), rotational speed (up to 15,000 rpm), and materials like aluminum alloy and stainless steel. These couplings use radial set screws to fix the shaft and are known for zero backlash and accommodating axial, angular, and lateral misalignment.Key specificationsBore Diameter: Typically ranges from 3 mm to 28 mm, depending on the model.Outer Diameter: Varies by size, with a range of 16 mm to 40 mm.Overall Length: Depends on the size, often from 20 mm to 54 mm.Torque Capacity: Can range from as low as \(0.5\) Nm to \(12\) Nm or higher.Rotational Speed (\(n_{max}\)): Can reach up to 15,000 rpm.Materials: Commonly made from aluminum alloy for the body and stainless steel for the bellow.Clamping Method: Radial set screws are used for shaft tightening.Performance and features
