Shaft coupling dimensions: 0.59 x 0.79 inches/15 x 20mm (Dia x L), Connection Bore Diameter: 6.35mm to 6.35mm. Package: 4 Flexible Couplers.
Flexible shaft couplings are suitable for a variety of applications, including 3D printers, CNC machine tools, stepper motors, photoelectric encoders, and other automation equipment. Easily connect and calibrate motors, shafts, and guideways in both DIY and professional machines.
The motor couplers' helical cut design compensate for angular, parallel, and axis misalignments between the connecting shafts. This flexibility absorbs vibration and shock loads, protecting your delicate motors and bearings from damage. The result is smoother operation, lower noise, and extended service life for mechanical components.
NOTE: During installation, ensure that the two shafts are aligned as much as possible, and then tighten the set screws on both sides evenly to avoid excessive force on one side, which may result in clamping that is not secure or damage to the shaft surface.
The coupler joint is made of premium aluminum alloy, combining excellent strength with lightweight construction. This material offers outstanding corrosion resistance and ensures long-term reliability, and provides some shock absorption and cushioning effects to protect the equipment.
