2PCS 5mm to 8mm Flexible Shaft Coupling Helical Beam Coupler

Key features

• Compact and Secure Design: This flexible shaft coupling is designed to connect 5mm and 8mm shafts. Diameter: 19mm; Length: 25mm. The compact coupling design features set screws that securely lock onto the shaft for reliable power transfer. A correctly sized Allen wrench is included for easy assembly.
• Premium Aluminum Alloy Construction: Built from high-quality aluminum alloy, this flexible helical beam coupling uses a precision-machined one-piece design to provide lasting durability, corrosion protection, and lightweight performance.
• Helical Flexible Design: Featuring a spiral cut body, this stepper motor coupling effectively compensates for slight shaft misalignment while helping improve transmission reliability and reduce installation stress.
• Smooth and Precise Motion Transfer: The flexible shaft coupler delivers efficient rotary motion transmission, minimizing vibration and backlash to achieve smooth, precise system performance.
• Wide Applications: Designed to connect stepper motors, servo motors, encoders, lead screws, and similar rotating components. Ideal for robotics, CNC machines, 3D printers, engraving equipment, and automation applications.
