The global shift to electrification and automation is reshaping requirements for drivetrain components — and Qingzhou Jianfu Gear is ready to meet overseas OEM and aftermarket demand with precision custom ring and pinion gears, spiral bevel gear sets, and durable differential ring gear and crown wheel and pinion assemblies. Major suppliers are introducing multi-speed and high-torque e-axles to serve passenger and commercial EVs, pushing gearmakers to deliver quieter, higher-precision final drives for electrified powertrains. For heavy trucks and off-road machinery, the need for robust, high-torque ring-and-pinion solutions is growing — manufacturers now offer heavy-duty aftermarket ring-and-pinion kits and integrated e-transmission systems capable of several thousand newton-metres of torque. Jianfu’s production lines are optimized to supply these heavy-duty crown wheel and pinion and custom ring and pinion gears to fleets and OEMs across Europe, North America and Southeast Asia. Quiet NVH performance is essential for modern EVs. Advanced simulation tools and engineering methods — including bevel-gear contact simulation — let engineers optimize spiral bevel gear geometry and tooth micro-geometry to reduce noise and vibration before manufacture. Jianfu combines CAD-driven design checks with precision finishing (small-module grinding, gear honing and tailored heat treatments) to deliver low-NVH differential ring gear assemblies for electric and hybrid drivetrains. Agricultural and industrial transmissions continue to demand reliable gear sets even as electrified tractors and machines emerge. Battery tractors in the 100-hp class still rely on proven differential and final-drive designs, so suppliers that can provide both traditional differential ring gear and next-generation spiral bevel gear solutions hold an advantage in cross-sector export markets. Jianfu’s experience with farm, industrial and automotive gearing positions the company to serve growing overseas orders. Manufacturing trends favor tighter tolerances and advanced surface treatments to extend gear life under higher loads and faster pitch-line speeds. Jianfu invests in CNC generating grinders, automated inspection and coating capabilities to meet stringent EV and heavy-equipment specifications — enabling customers to reduce downtime and increase drivetrain efficiency. Get tailored gear solutions for your application — whether you need heavy-duty custom ring and pinion gears, precision spiral bevel gear sets, or durable crown wheel and pinion / differential ring gear assemblies for EVs, trucks, tractors or industrial drives. 📩 Contact: harry@jianfugear.com
