1Pcs Three-Section Universal Joint Coupling 4/5/6/8/10Mm 45# Steel Boat Car Shaft Coupler With Screw Metal Cardan Joint

Description: 1. Wear Resistance: Premium 45# steel material, withstands long-term high-torque operation without rust, abrasion or deformation, extends product service life and lowers replacement cost. 2. Flexible Angular Transmission: Precision swivel joint structure, supports up to 45° angular misalignment for power transfer between non-coaxial shafts, eliminates shaft alignment stress and improves overall transmission efficiency. 3. Secure Non-Slip Connection: Pre-drilled set screw mounting holes, fastens tightly to connected shafts even under high-speed rotation, ensures stable power output and avoids accidental falling off during operation. 4. Smooth Low-Friction Operation: Polished contact surface with embedded high-hardness bearing pins, minimizes rotation friction and component wear, reduces working noise and delivers consistent smooth transmission performance. 5. Wide Compatibility: Fits most common 4/5/6/8/10mm diameter shafts for various devices, meets diverse demands of RC models, 3D printers and DIY mechanical projects without extra modification.
