Ningbo JEC Shaft Manufacturing Co., Ltd. (formerly known as NINGBO JIECHENG AXLE TRADE CO., LTD.) is a leading supplier specializing in the precision machining of a wide range of shafts, including those used in the automotive industry. Founded in 1989 in Ningbo, Zhejiang Province, China, the company has undergone nearly 40 years of steady development. We currently employ over 200 staff members, including a dedicated technical team of more than 20 engineers.
With total fixed assets of RMB 240 million and a factory spanning over 20,000 square meters, we boast an annual production capacity exceeding 60 million precision-machined parts. Equipped with advanced domestic and international shaft machining equipment and precision testing instruments, our production technology ranks at the forefront of the domestic industry.
Our customer base spans both China and international markets, including the UK, USA, Mexico, Japan, and the Czech Republic — and we are actively expanding our partnerships with Spanish and broader European clients.
Committed to development and innovation, we invest significant resources annually in new product R&D and technical upgrades. We have developed and successfully mass-produced a variety of shaft products, including welded shafts, gear shafts, servo motor shafts, wiper shafts, knurled shafts, and milling-edge shafts. Our portfolio also features new energy product lines such as electronic adjustment columns, ONE-BOX brake motor shafts, and E-bike powertrain motor shafts.
Spain is one of Europe's most dynamic industrial economies, with a strong manufacturing base spanning automotive, renewable energy, food processing, and advanced machinery. The demand for precision motor shafts in Spain continues to grow as industries modernize and embrace automation and electrification.
Spain is the second-largest automotive producer in Europe. Major OEMs including SEAT (Volkswagen Group), Stellantis, and Renault operate large-scale plants in Barcelona, Zaragoza, and Valencia. These facilities require millions of precision motor shafts annually for EV drivetrains, wiper systems, brake actuators, and steering mechanisms — creating a significant and sustained demand for high-quality shaft components from trusted global suppliers.
Spain ranks among Europe's top producers of wind and solar energy. The rapid expansion of wind turbine installations across Castilla y León, Galicia, and Aragón has driven strong demand for industrial-grade motor shafts used in generator assemblies and pitch control systems. Solar-tracking systems also rely on precision shafts for reliable angular positioning, making this sector a growing application area for our products.
Spain's manufacturing sector is undergoing a significant digital transformation under the "Industria Conectada 4.0" initiative. Factories in the Basque Country, Catalonia, and Madrid are increasingly adopting robotic assembly lines, CNC machining centers, and automated conveyor systems — all of which depend on servo motor shafts and precision splined shafts to achieve the accuracy and repeatability required in modern production environments.
With an extensive network of irrigation systems, desalination plants, and municipal water supply infrastructure — particularly in Andalucía, Murcia, and the Canary Islands — Spain has a constant need for durable pump motor shafts. Our friction-welded and precision-machined pump shafts are engineered to withstand continuous operation in demanding fluid environments, meeting the reliability standards required by Spanish water utilities and agricultural operators.
The Spanish e-mobility market is booming, with e-bike sales growing at double-digit rates year-on-year. Urban centers like Madrid, Barcelona, and Seville have invested heavily in cycling infrastructure. Our E-bike powertrain motor shafts and compact servo motor shafts are ideally suited for the mid-drive motor systems used in pedelec bicycles, cargo e-bikes, and urban electric scooters distributed across the Iberian Peninsula.
Spain is Europe's largest agricultural exporter, with major food processing clusters in Valencia, Almería, and La Rioja. Industrial blowers, conveyor motors, and packaging machinery in these facilities rely on robust motor shafts that can endure continuous duty cycles in humid, corrosive environments. Our knurled shafts and industrial motor shafts are precision-engineered to meet the demanding hygiene and durability standards of the Spanish agri-food processing sector.
The European Green Deal and Spain's National Energy and Climate Plan (NECP) are accelerating the transition to electric vehicles, renewable energy, and energy-efficient industrial systems. This transformation is fundamentally reshaping the demand profile for precision motor shafts — requiring components that are lighter, stronger, and capable of operating at higher speeds and temperatures than ever before.
Spain's commitment to banning combustion engine vehicle sales by 2035 is pushing automakers to rapidly scale EV production. This drives exponential demand for high-precision ONE-BOX brake motor shafts, EPS motor shafts, and e-axle components that meet stringent NVH and dimensional tolerances.
Spain's adoption of collaborative robots (cobots) and multi-axis robotic arms in automotive and electronics manufacturing is accelerating. Servo motor shafts with ultra-tight tolerances (IT5–IT6) and superior surface finishes are essential for the joint actuators and end-effectors in these systems.
As Spain develops gigafactory capacity and grid-scale battery storage, precision cooling pump shafts and thermal management system components are increasingly in demand. Our welded shafts and pump motor shafts are engineered for the reliability required in battery thermal management applications.
European OEMs are demanding smaller, lighter motor shaft solutions without compromising on torque capacity or fatigue life. Our investment in advanced CNC grinding, friction welding, and surface treatment technologies enables us to produce shafts with optimized cross-sections that reduce weight by up to 20% versus conventional designs.
Post-pandemic supply chain disruptions have prompted Spanish manufacturers to diversify their supplier base and establish dual-sourcing strategies. Chinese precision component manufacturers with proven quality systems (IATF 16949) and competitive lead times are increasingly preferred as strategic partners for European industrial buyers.
Spain's alignment with EU environmental regulations (CBAM, REACH, RoHS) means that suppliers must demonstrate environmental compliance. Our ISO 14001:2015 certification and Green Factory designation ensure that our manufacturing processes meet the sustainability criteria demanded by Spanish and EU procurement teams.
