Description
XB Flexible Aluminum Alloy Spider Jaw Coupling 55mm OD x 78mm Length x 14mm-14mm Bore
The XB Flexible Aluminum Alloy Spider Jaw Coupling is a durable and high-performance shaft coupling designed to connect two 14mm shafts while providing smooth and reliable torque transmission. With a 55mm outer diameter and 78mm total length, this coupling is suitable for motors, encoders, gearboxes, CNC systems, and automation assemblies where stable shaft connection, shock absorption, and vibration reduction are important. Its flexible jaw spider structure helps compensate for slight shaft misalignment during operation.Built for precision mechanical transmission, this coupling supports a rated torque of 46 Nm, maximum torque of 92 Nm, and rotational speeds up to 8000 rpm. It also allows 0.02mm radial deviation, 1.0° angular deviation, and +0.80mm axial deviation, making it suitable for robotics, machine tools, motion control systems, and various industrial power transmission applications.
