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. Now we proudly extend our services to the Bulgaria market, offering high-quality 3mm motor shafts and custom precision shaft solutions tailored to Bulgarian industrial needs.
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.
Bulgaria has emerged as one of Central and Eastern Europe's most dynamic manufacturing hubs. With a growing automotive assembly sector, expanding EV infrastructure, and a thriving electronics and precision engineering industry, demand for high-quality 3mm motor shafts has surged significantly in recent years. Cities like Plovdiv, Sofia, and Varna host numerous industrial parks where precision motor components are in constant demand.
Bulgaria hosts major tier-1 and tier-2 automotive suppliers serving European OEMs. Factories in Plovdiv and Troyan require precision 3mm motor shafts for EPS systems, wiper motors, brake actuators, and HVAC fan assemblies. Demand for compact, high-tolerance shafts is growing in line with EU vehicle electrification mandates.
Bulgaria's adoption of electric vehicles is accelerating, driven by EU Green Deal targets. E-bike assembly plants and EV component manufacturers across Sofia and Gabrovo are actively sourcing precision motor shafts for powertrain systems. Our 3mm motor shaft solutions for E-bike and EV motors are perfectly aligned with this fast-growing segment.
Bulgaria's industrial automation sector is expanding rapidly, with significant investment in CNC machining centers, robotic assembly lines, and servo-driven equipment. Precision 3mm motor shafts are critical components in servo motors and automation drives used across Bulgarian manufacturing facilities in Ruse, Stara Zagora, and Burgas.
The EU's 2035 ban on combustion-engine vehicles is pushing Bulgarian automotive suppliers to pivot toward EV components. This directly drives demand for compact, high-precision motor shafts used in electric drivetrains, brake-by-wire systems, and electronic steering.
Bulgarian factories are rapidly adopting smart manufacturing technologies. CNC machining centers and servo-controlled robotic arms require ultra-precise 3mm motor shafts with tight tolerances. Our shafts meet the highest precision standards demanded by Industry 4.0 environments.
Bulgaria's construction boom and energy efficiency upgrades are fueling demand for HVAC systems. Fan coil units and air handling units require reliable motor shafts. Our custom fan coil unit shafts are widely used in commercial HVAC applications across Bulgarian cities.
Bulgaria's agricultural sector — one of the largest in Southeast Europe — is rapidly mechanizing. Blowers, irrigation pumps, and processing equipment require durable motor shafts. Our industrial motor shafts deliver the reliability needed for Bulgaria's demanding agri-industrial applications.
Bulgaria is investing heavily in rail infrastructure modernization under EU cohesion funds. Rail transportation systems require precision-engineered motor shafts for traction motors, auxiliary drives, and door mechanisms — all areas where our high-performance shafts excel.
As part of the Belt and Road Initiative and expanding EU–China trade, Bulgarian importers are increasingly sourcing precision components directly from Chinese manufacturers. Our established export infrastructure ensures fast, reliable delivery of 3mm motor shafts to Bulgarian customers.
From Sofia's automotive clusters to Plovdiv's industrial parks and Varna's port logistics hubs — Bulgarian manufacturers trust our precision-engineered 3mm motor shafts for their unmatched dimensional accuracy (±0.001mm tolerance), superior surface finish, and compliance with EU quality standards. With IATF 16949 certification and 35+ years of export experience, we are your most reliable China-based motor shaft supplier for the Bulgarian market.
