Coupler jaw Spider 8 x 8mm (25mm)
This high-quality Aluminum Jaw Spider Coupler is designed to connect stepper motors to lead screws, delivering high torque transfer with excellent vibration damping. The polyurethane spider insert allows for zero backlash and smooth operation at speeds up to 17,000 RPM. Its design compensates for angular, radial, and axial misalignments, making it ideal for CNC machines, 3D printers, and other motion control systems.
With a firm grip and simple installation, this coupler offers corrosion resistance, high durability, and reliable performance in demanding applications. The aluminum alloy body provides structural integrity, while the elastomer spider absorbs shocks and helps maintain constant velocity during rotation.

Why Use Jaw Spider Couplers Instead of Flex or Fixed Couplers
Jaw Spider Couplers provide a balanced combination of strength, flexibility, and precision. Compared to flex couplers, which can fatigue over time and amplify vibration, jaw couplers dampen vibration effectively while allowing for small misalignments. Unlike rigid (fixed) couplers that transfer all shock loads to connected components, jaw couplers absorb these shocks with their elastomer insert, reducing wear and tear. This makes them ideal for systems requiring long-term accuracy and reduced mechanical stress.
