About Our Company

Wuxi Zejia Technology Co., Ltd. Company Profile Wuxi Zejia Technology Co., Ltd. is a professional manufacturer integrating R&D, non‑standard custom manufacturing, sales and technical services of mechanical transmission components, electric control technologies and various mechanical parts. Founded in 2012 with a registered capital of RMB 5.06 million and a factory covering 10 mu of land, the company has accumulated core mechatronic technologies over more than a decade, and keeps translating advanced technologies into practical industrial applications. Faced with the increasingly high‑end, customized and diversified market demands, we rely on our in‑house professional expertise and engineering capabilities to develop highly reliable and adaptable innovative transmission products. We have rich manufacturing experience in non‑standard customized shafts, splines, gears, safety couplings, hydraulic couplings and quick‑mount couplings. Our self‑developed products including hydraulic serpentine spring couplings, hydraulic safety couplings, hydraulic ZL couplings, hydraulic shrink discs and taper‑bush couplings feature easy installation and maintenance, serving as viable alternatives to imported equivalents and winning wide recognition from customers. Multiple cutting‑edge products, such as universal couplings, diaphragm/disc couplings, permanent‑magnet couplings, wind‑power‑specific couplings, magnetic sensors, contact‑free high‑reliability sensors, resin couplings and carbon‑fiber couplings, are under national and international patent applications. These products are gradually being adopted in key sectors including nuclear power, aerospace and high‑end energy‑equipment manufacturing. Located in Wuxi, Jiangsu Province, the company sits in the core area of the Yangtze River Delta advanced manufacturing cluster, with convenient access to ports and expressway networks, bringing outstanding supply‑chain and geographical advantages. We are capable of developing high‑precision transmission components and achieving mass production. Equipped with advanced processing and testing equipment and a skilled technical team, we maintain long‑term industry‑university‑research cooperation with Southeast University. All product designs are completed with SolidWorks and UG 3D digital design software, enabling rapid parameter verification, 3D modeling, finite‑element analysis and 2D engineering drawing creation, which greatly improves the R&D efficiency and reliability of new transmission parts and mechanical components. The company has built a sound quality‑management system and obtained ISO 9001:2008 certification. Adhering to the business tenet of Quality First, Integrity‑Oriented, we absorb advanced domestic and overseas transmission technologies, pursue continuous innovation, and strive to deliver cost‑effective solutions for our customers. We operate five production bases in Wuxi, Yancheng, Chongqing, Hebei and Anhui. As one of China’s large‑scale manufacturers of couplings and taper‑bush pulleys, we offer more than forty product series with an annual production capacity of 14,200 tons. Standard‑product lead time is 10‑15 days, while small‑batch urgent orders can be fulfilled within 3‑7 days, featuring flexible response and stable delivery. Main Product Portfolio Couplings XL/ML/LM star‑type & plum‑blossom couplings, TL/HL/LX elastic couplings, ZL gear‑type elastic couplings, DJM/SJM/ZDJM diaphragm couplings, disc‑type couplings, serpentine‑spring couplings, gear‑tooth couplings (CL/GICL/GIICL/NGCL/WG series), permanent‑magnet / contact‑free couplings, high‑temperature‑resistant couplings, ball‑type couplings, high‑rigidity servo flexible couplings, etc. Universal Shafts & Ball‑cage Synchronous Universal Couplings Full‑range SWC, SWP, SWL cross‑cardan universal shafts; BJ‑ / BHJ‑ / HTJ‑ / BC‑ / DOJ‑ series ball‑cage synchronous universal couplings. Applications cover construction machinery, commercial vehicles, rolling mills, crushers, petroleum machinery, papermaking equipment, cement plants, dynamometers, agricultural‑machinery PTO drives and carbon‑fiber drive shafts. Safety Components (Torque Limiters) AQ/AF/MGB/MSH/MQ/ME‑MEF/MA/XF‑XC/MJF‑MJC/MFT/CTL/MF/MD series ball‑type, friction‑type and sliding‑pin torque limiters, axial‑force limiters and torque retainers, which can replace imported brands such as KTR and Comintec. Taper‑bush Transmission Parts European‑standard SPZ/SPA/SPB/SPC pulleys, American‑standard 3V/5V/8V pulleys, taper‑bush timing pulleys, sprockets, gears, TB and QD taper bushes. Other Components, Non‑standard Customization & Repair Services Shrink discs, backstops, retaining rings, fan shaft discs, custom shafts, splines and gears. We own laser‑cladding equipment to provide repair services for rollers, rolling‑mill bearing blocks, universal shafts and other parts. Our products can serve as drop‑in alternatives for parts from international brands including FALK, GWB, EBLE, Voith, Lovejoy, Martin, SKF, TB Woods, ESCO, Fenner, FLENDER, R+W, Comintec, DST, John Crane and Dodge. Our products are widely applied in power generation, metallurgy, coal mining, petroleum, chemical engineering, agricultural machinery, construction machinery, rail transit, aerospace and other industries, and are exported to Europe, America, the Middle East and Southeast Asia. Core strengths: Complete product range, strong custom‑manufacturing capability, comprehensive testing, controllable lead time and competitive cost, ideal for replacing expensive imported components. Drawing on advanced European and American management concepts and absorbing merits of global transmission technologies, we keep our products at the forefront of the industry. With premium quality, fast delivery and comprehensive after‑sales support, we have become the preferred supplier for numerous manufacturers and end‑users. We sincerely welcome customers to visit our facilities for on‑site inspection, technical exchange and business negotiation.
