Rear Propeller Shaft C1100021261 for Mining Equipment

The C1100021261 rear propeller shaft is a high-performance driveline component engineered for heavy-duty mining machinery. Constructed with 20CrMnTi alloy steel (1080 MPa tensile strength), it delivers a torque capacity of 30,000-50,000 N·m while maintaining IP67-rated dust and water immersion protection. The shaft features a three-section telescopic design with φ57 cross-axis universal joints, allowing angular compensation up to 15° and seamless integration with mining trucks, loaders, and excavators. Its dual-bearing intermediate support reduces vibration by 40% during high-speed operation (≤3000 RPM), while the electrophoretic coating (100μm thickness) ensures 1000+ hours of salt spray resistance. The shaft undergoes rigorous dynamic balancing to G2.5 standards, minimizing noise and extending drivetrain lifespan by 30% in abrasive mine environments.
