Transmission Intermediate Shaft

This transmission intermediate shaft acts as a power bridge in your shuttle shift transmission, connecting the main drive shaft to the driven shaft. It enables smooth switching between forward and reverse gears. At Yancheng Botu Transmission Machinery, we manufacture this shaft from high-strength 42CrMo steel. It undergoes quenching and tempering, and the journal is high-frequency hardened. The spline is precision-machined, ensuring smooth and reliable power transfer. A solid transmission intermediate shaft keeps the entire gearbox operating correctly.

The combination of 42CrMo steel and our tempering process provides a tensile strength of 950 MPa or higher, strong enough to withstand torque shocks during shifting. The spline teeth are high-frequency hardened to HRC 50–55, providing excellent wear resistance even after repeated shifts. Center holes on both ends are machined with precision to maintain coaxiality within 0.02 mm. This ensures your transmission intermediate shaft remains true and durable over time.

With 8 years of experience in manufacturing transmission components, we have in-depth knowledge of shuttle shift systems and the forces acting on intermediate shafts during gear changes. That is why we optimize materials and heat treatment for this specific application. Full CNC equipment-including CNC lathes, CNC spline mills, and CNC cylindrical grinders-is used to ensure high accuracy. Machines are regularly calibrated, and every transmission intermediate shaft comes with a 1-year warranty. Fast after-sales service is provided, and any quality issue will be repaired or replaced free of charge.
