JXL high-precision bearings drive the future of new energy vehicles
[Core innovator of electric drive systems]
As a technological pioneer in the field of new energy transmission, JXL focuses on the research and development of intelligent bearing systems that meet the ISO 26262 functional safety standards. Our products have passed the IATF 16949 system certification, meeting the stringent requirements of the three-electric system (motor, electronic control, battery), providing core support for cutting-edge technologies such as 800V high-voltage platforms and silicon carbide electric drives, and helping to increase the energy efficiency of the entire vehicle to 98.5%.
▌Six major technical breakthroughs in new energy transmission
Directly address the core challenges of the industry:
• Ultra-high-speed operation stability of the motor shaft at 20,000rpm
• NVH optimization of the electric drive system (vibration value <0.03mm/s²)
• -40℃ extreme cold to 180℃ high temperature cycle impact tolerance
• Lightweight integrated design (component weight reduction of 35%+)
• Electromagnetic compatibility guarantee (anti-leakage magnetic interference >95%)
• 300,000 km life verification (zero maintenance design)
