Founded in Changzhou in 1995 with a supporting office in Shanghai, Changzhou Qingtan Special Bearing Co., Ltd. Has established itself as a leading and innovative manufacturer specializing in the design, development, and production of high-precision special bearings, leveraging a strategic long-term partnership with BTC to serve a global clientele. Operating from a modern 20, 000 square meter factory equipped with over 100 sets of advanced production and precision inspection machinery and powered by a dedicated team of approximately 90 skilled professionals, the company combines scale with expertise, achieving a turnover of around 6 million Euros in 2024. Our core specialization lies in engineering and delivering superior bearing solutions, most notably in One-Way Clutches and Overrunning Clutches (including Drawn-Cup Roller Clutches), a comprehensive range of Needle Roller Bearings (encompassing Drawn-Cup types-both open-end and closed-end-Radial Needle Roller Bearings, and Track Rollers), Axial/Thrust Bearings such as Axial Needle Roller and Cage Assemblies, critical Precision Components like Needle Roller and Cage Assemblies (both radial and axial), Inner Rings, and Needle Rollers, as well as durable Powder Metallurgy Bearings, all designed for exceptional performance, longevity, and reliability in the most demanding applications. Quality and sustainability are foundational to our operations, validated by IATF 16949: 2016 certification for automotive quality management, ISO 14001: 2015 for environmental management, recognition as a National High-Tech Enterprise (2022) and a Specialized & Innovative SME (2023), alongside Safety Production Standardization certification, with all processes guided by rigorous principles like Bosch Q-Basics 14. Our commitment to innovation is demonstrated through our portfolio of 21 National Patents for special bearing and clutch technologies, our contribution to drafting the Chinese industry standard for Drawn-Cup Roller Clutches (JB/T 11251-2011), the official recognition of our Drawn-Cup Roller Clutch and Efficient Torque Transfer Bearing as High-Tech Products, and a proven development history from pioneering HK series bearings and HF series one-way clutches to advanced powder metallurgy lines and successive generations of eBike drive system components. This technical excellence is enabled by our advanced in-house manufacturing and inspection capabilities, which include multi-station punching machines (200T, 300T), automated assembly lines for one-way and needle roller bearings, heat-treatment furnaces, and a comprehensive suite of precision testing equipment such as AOI (Automatic Optical Inspection) systems, roundness meters, micro and Rockwell hardness testers, mechanical performance testers, and dedicated lifecycle testers for one-way clutches, ensuring total vertical control over quality and reliability. Our bearings are integral components across diverse industries including Automotive Systems, Electric Bicycles (eBike) & Micromobility, Industrial Machinery & Automation, Transmission Systems, Agricultural Machinery, Power Tools, and Precision Instruments. At Qingtan Bearing, we position ourselves as a trusted solutions partner, committed to collaborating closely with clients to overcome challenges and provide bearing innovations that enhance product performance, durability, and overall value, inviting you to connect with us to experience our dedication to engineering excellence in motion.
