Deep compatibility in the automotive field: The product is applied to key parts such as engines, gearboxes, wheels, and motors, and is compatible with mainstream models in Europe, America, Japan, South Korea, and China.
Technical compliance: Complies with ISO 9001 standards and supports customized certification.
Quality Assurance: Ensure that the exported bearings meet international standards and customer requirements. If any quality problems are found, we will take responsibility and provide replacement or compensation.
Intelligent warehousing: Shanghai Port has a 1,500-square-meter quality inspection and warehousing center, ensuring worry-free shipping.

Ii. Bearing Solutions for Automotive Parts
1.Bearings for drive motors of new energy vehicles
Pain points: High rotational speed (15,000+ RPM), electromagnetic interference, lubrication challenges → electrical corrosion, early failure
Solution
Product
Ceramic hybrid bearings (Si₃N₄rolling elements + stainless steel rings), insulating and resistant to electrical corrosion.
Low-noise sealed deep groove ball bearings (62/63 series) have NVH performance that is 5dB better than the industry standard.
Case: Provided motor bearings for a certain European electric vehicle brand, achieving zero-fault operation for 200,000 kilometers.
2. Hub unit bearings
Pain points: Complex road conditions impact, mud and water corrosion, lifetime maintenance-free demand → Seal failure, abnormal noise
Solution
Product
The third-generation hub bearing unit (integrated ABS sensor slot) supports an integrated design for axial/radial loads.
Fluororubber sealing lip + special grease (-40℃ to 180℃), dust and water resistance rating IP6K to 9K.
Value: The lifespan of hub bearings for Middle Eastern customers in dusty environments has been increased by three times.
3. Bearings for transmission and engine accessories
Pain points: High temperature, oil contamination, high load → wear, excessive noise
Solution
Product
Needle roller bearings for transmission (RNA/NK series), with surface phosphating treatment, have a 50% increase in anti-seizing capacity. Tensioning wheel bearings (with self-locking riveting structure), prevent detachment due to high-speed centrifugal force.
Service: Provide heat treatment process reports and metallographic analysis data.
