Description
XB Flexible Aluminum Alloy Spider Jaw Coupling 105mm OD x 140mm Length x 35mm-35mm Bore
The XB Flexible Aluminum Alloy Spider Jaw Coupling is a durable and high-performance shaft coupling designed to connect two 35mm shafts while providing smooth and reliable torque transmission. With a 105mm outer diameter and 140mm 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 430 Nm, maximum torque of 860 Nm, and rotational speeds up to 3400 rpm. It also allows 0.02mm radial deviation, 1.0° angular deviation, and +1.00mm axial deviation, making it suitable for heavy-duty machinery, motion control systems, industrial drive assemblies, and various power transmission applications.
