Set Screw Precision Flexible Shaft Couplings

aluminum shaft couplings, spiral couplings, helical beam couplings, parallel couplings, slit couplings, encoder applications, stepper drive applications, linear test systems, scientific instruments. Our aluminum shaft couplings are perfect for various applications, including encoder and stepper drive applications, linear test systems, and scientific instruments. These couplings come in spiral and parallel designs, both lightweight and corrosion-resistant. Tighten the set screws to fasten them to your shaft, allowing for zero backlash and a strong hold without marring the shaft. Spiral couplings are flexible enough to handle parallel, axial, and angular misalignment, while parallel couplings offer rigidity and high torque capabilities. Shop now for aluminum shaft couplings that will meet your needs!
