8/8 mm Rigid Aluminum Coupling

Rigid coupling with holes of 8mm and 8mm diameter is intended for rigid coupling of various shafts in 3D-printing and CNC machines. The coupling is perfect for servo motors, stepper motors, encoders, trapezoidal screws etc. Cushioned, flexible aluminum coupling is used in 3D printers, milling machines and 3D plotters to transfer the drive from the Z-axis stepper motors to the guide, rod. Product features Aluminum coupling for RepRap 3D printers. Clamped with Allen screws. Characterized by low weight and a small moment of inertia with high transmitted torque. Technical data Hole diameters: I - 8 mm II - 8 mm Outer diameter: 20 mm Length: 25 mm

Allen key wrench size: 2.5mm
