Transmission Shift Shaft

Our transmission shift shaft is a core element in the gear-shifting systems of automobiles, motorcycles, and construction machinery. This product transmits shifting force and enables precise gear engagement, directly impacting shifting smoothness and operational reliability. Made from quality alloy steels like 45# steel and 20CrMnTi, and treated with tempering and localized quenching, each transmission shift shaft achieves an optimal balance of strength and toughness, with key areas hardened to HRC50-55.

We manufacture shafts from 8–50mm in diameter and 100–600mm in length, machining shift fork grooves, positioning holes, threaded connections, and splines to your specifications. Straight and stepped shaft designs are both supported. Our high-precision CNC lathes and milling centers control groove tolerances within ±0.01mm and hole position accuracy ≤0.02mm, ensuring exact alignment and consistent performance.

Surface treatments like phosphating and electrophoresis improve corrosion resistance, while fatigue testing validates longevity under frequent shifting cycles. Widely used in passenger car, commercial vehicle, motorcycle, and construction equipment transmissions, our product can be customized from your drawings, samples, or transmission model data. Choose our transmission shift shaft for precise, durable, and reliable shifting operation.
