Extending Bearing Quality Control to the Entire Vehicle Chassis System
Hangzhou, China – March 2026 In the automotive parts manufacturing industry, when suppliers expand their product lines, quality control is often diluted. However, as an industry leader with 15 years of OEM-level manufacturing experience, PRORUN is delivering a robust solution to the global market. With PRORUN officially expanding its product line to over 5000 SKUs across 10 major categories including suspension, braking, transmission, and motors, it adheres to “micron-level precision,” extending stringent bearing-level laboratory testing standards 100% to every component of the entire vehicle chassis and powertrain.
PRORUN’s technological strength stems from its deep R&D capabilities accumulated in its core product—the Wheel Hub Assembly.
When a vehicle is traveling at 120 km/h, the wheel hub unit must withstand thousands of dynamic loads per minute. To this end, PRORUN has established four industry-leading core testing systems:
ix-Component Force Durability Testing:Strictly adhering to ISO 16750-3 to reproduce the full lifecycle load spectrum, ensuring structural stability under high pressure.
Sensor Function Verification:Based on the ISO 26262 functional safety concept, ensuring ABS/wheel speed sensor signal distortion is below 5% within a wide temperature range of -40℃ to 150℃ and under high-frequency vibration of 5-500Hz.
Microscopic Leakage Prevention and NVH Testing:Conducting 24-hour leak testing at 2000 rpm, precisely controlling residual imbalance to ≤5 g·mm (ISO 1940-1), achieving ultimate quietness.
Quality Control Shift: TS16949 Commitment Across 10 Major Product Categories
Today, PRORUN’s 100+ partner brands and customers in over 70 countries worldwide are benefiting from this revolutionary quality management system. All PRORUN export products are TS16949 certified and undergo 100% inspection before leaving the factory.
For different systems, the PRORUN R&D team has customized stringent testing solutions:
For suspension and steering systems (such as control arms, shock absorbers, and ball joints): Taking into full account the complex mountainous and gravel road conditions in markets like South America, PRORUN has introduced extremely high-intensity impact fatigue testing and tear resistance testing for rubber bushings to ensure the components’ tensile strength under extreme bumps.
For braking and motor systems (such as brake discs/pads and air conditioning compressors): Considering the extremely hot weather in markets like the Middle East, the focus is on high-temperature thermal fade testing, seal anti-aging testing, and refrigerant circulation efficiency testing to ensure braking safety and motor lifespan.
Technology Empowers Business: OEM/ODM Customization and Extended Warranties
Powerful technical testing capabilities are not only used for quality control of standard products but also transformed into a powerful business tool for PRORUN’s B2B partners.
In-depth OEM & ODM Services: As long as customers provide 3D data or actual vehicle operating parameters, PRORUN’s R&D team can generate a “Design Optimization Proposal,” transforming test data into product improvement solutions and custom-designing exclusive parts for you.
Impeccable Warranty Commitment: Based on 100% full inspection, PRORUN confidently offers global customers an extended warranty of 15 months or 50,000 kilometers.
72-Hour Closed-Loop Technical Service: We provide 24/7 response. Once the RMA (Return and Exchange) process is triggered, the team will respond rapidly within 48 hours and provide complete technical analysis feedback within 72 hours.
