D20*L25 Flexible Shaft Coupling, 6mm to 6mm Bore, Aluminum Plum Connector for 3D Printers, CNC Machines, and Servo/Stepper Motors
Product description
Flexible Shaft Coupling
High-Precision Aluminum Flexible Coupling for Stepper and Servo Motors
Made of high-quality aluminum alloy, this plum flexible shaft coupling offers excellent torsional rigidity and shock absorption. Ideal for stepper motors, servo motors, and encoder connections. Easy to install with clamping screws. Red elastomer insert ensures vibration damping and misalignment compensation.
Premium Build with H7 Precision and 12.9-Grade Fasteners
Anodized 6061-T6 Aluminum Coupling with 98 Shore A Polyurethane CorePrecision Coupling Built with Grade 12.9 Screws and H7 Tolerance HolesHigh-Strength Aluminum Shaft Coupler with Plug Gauge Inspected H7 HolesPremium Flexible Coupling – 6061-T6 Aluminum, H7 Fit, and 98A PolyurethaneReliable Power Transmission with 12.9 Screws and Plug Gauge-Verified Accuracy
R-Type Chamfer for Stress Reduction in Shaft Couplings
This flexible shaft coupling features an R-type chamfer at the cut seam to reduce sharp internal corners. This helps lower the risk of stress concentration in areas subject to frequent torque changes.
The R-radius fillet allows for more even load distribution during use. Suitable for applications such as CNC equipment, stepper motors, and servo systems, where precision shaft coupling performance is important.
