From Bearing to Chassis and Powertrain Integration Supplier
Hangzhou, China – In 2026, Hangzhou Prorun Auto Parts Co., Ltd. (hereinafter referred to as “PRORUN”) officially announced its most significant strategic upgrade in its 15-year history: the company has successfully transformed from a “specialized wheel bearing supplier” into a “full vehicle chassis and powertrain integration supplier” covering 10 core categories. Currently, PRORUN’s product line comprehensively covers more than 100 mainstream automotive brands, and it has successfully developed and supplied over 5,000 SKUs of high-quality automotive parts to more than 70 countries and regions worldwide (deeply covering the South American, Middle Eastern, Indian, and African markets).
For the past 15 years, PRORUN has consistently focused on the design and production of OEM-quality automotive bearings, covering the entire industry chain from raw material forging to finished product production. We understand that the wheel hub unit, as the “intelligent joint” of the automotive chassis, directly determines the vehicle’s safety boundaries through millimeter-level tolerance control and rigorous durability testing (covering six-component load spectrum, high-frequency vibration resistance, and salt spray corrosion resistance).
Leveraging our newly established joint factory network and strong supply chain integration capabilities, PRORUN can now provide one-stop procurement services for global B2B partners. Our ten product categories not only meet daily replacement needs but are also optimized for extreme operating conditions in various regional markets:
Suspension and Steering Systems (for the hilly and bumpy road conditions of South America and India): Covering high-tenacity control arms, ball joints, steering gears, and shock absorbers/coil springs with extremely high impact resistance.
Braking Systems (for the extreme high-temperature climate of the Middle East): Providing brake calipers, brake discs, and high-performance brake pads that have undergone rigorous heat fade testing to ensure stable braking force even at high temperatures.
Transmission and Engine Core Components: Including constant velocity joints (CV joints), timing chain repair kits, cylinder heads, etc., ensuring efficient operation of the powertrain. Automotive Electronics & Motor Systems: Adapting to digital trends, we provide precision ABS wheel speed sensors, air conditioning compressors, alternators, and starters.
Core Strengths: Continuously leading the industry in wheel hub units and bearing repair kits, tensioners, and clutch bearings.
Faced with an increasingly complex international trade environment, overseas buyers are extremely eager for stable, reliable, and responsive supply chain systems. PRORUN, with its comprehensive operational support, builds a solid business foundation for its clients:
TS16949 Certification and 100% Inspection: Every product undergoes 100% rigorous inspection before leaving the factory, striving to reduce the defect rate to zero and fully comply with original equipment manufacturer (OEM) specifications.
15 Months / 50,000 km Extended Warranty: Our confidence in product quality translates into an extended commitment to the vital interests of our customers.
Rapid Response and 7-Day Shipping: Adhering to a 24/7 service philosophy, RMA (Returns & Exchanges) issues will be responded to within 48 hours, and technical feedback will be completed within 72 hours. We maintain stock of top-selling SKUs, supporting 7-day rapid shipping and small-batch replenishment, significantly alleviating dealers’ inventory capital pressure.
OEM & ODM Deep Customization: If customers provide relevant product data or samples, PRORUN’s professional R&D team can provide end-to-end customization services from design drawings to mass production.
Future Vision: From a precision wheel bearing to a complete safe and reliable chassis ecosystem, PRORUN is committed to bringing China’s top automotive components to the world. Customer satisfaction is our only standard. We look forward to establishing deep partnerships with global importers, wholesalers, and suppliers.
