In the wave of global automotive industry transformation towards electrification and intelligence, the e-drive system (e-Axle) of new energy vehicles (NEVs) serves as the "core heart" propelling the vehicle forward. As motor speeds continue to climb, wheel hub bearings and reducer bearings must withstand extremely high radial loads and axial impacts under extreme conditions of up to 20,000 RPM. However, traditional bearings are highly susceptible to lubrication failure due to internal friction heating during ultra-high-speed operation. Moreover, rotational friction losses directly consume the precious power of the battery pack, leading to a reduction in vehicle driving range. Top global automakers urgently need support bearings customized for pure electric drive platforms, featuring ultimate low-friction, high-speed, and long-life characteristics.

Facing the stringent NEV standards for "ultra-long driving range" and "full life-cycle maintenance-free operation," support systems must not only possess high-speed operating capabilities that break through physical limits but also maintain absolute operational smoothness and structural integrity within extremely compact internal spaces. Due to massive heat accumulation caused by high-speed friction between rolling elements and raceways, traditional bearings easily experience uncontrolled temperature rise. Furthermore, the friction resistance brought by conventional sealing structures directly causes unnecessary loss of overall vehicle energy efficiency. The market urgently demands an NEV dedicated bearing solution that can break through the dual bottlenecks of high-speed friction and energy efficiency degradation, achieving full life-cycle high-reliability operation and providing solid protection for the global popularization of green mobility.

NMT New Energy Vehicle Bearings are born to conquer the ultimate speed and energy efficiency challenges of pure electric drive systems. This series achieves disruptive breakthroughs in materials science and micro-geometric design. For low friction and high speed, NMT innovatively adopts ceramic hybrid rolling elements and laser micro-texturing raceway technology, reducing rotational friction by approximately 66% compared to traditional products, physically cutting off the source of energy loss. Meanwhile, the streamlined lightweight cage design significantly reduces centrifugal force during high-speed rotation, allowing the bearing's limit speed to perfectly match the new generation of coaxial e-Axle systems. For long life and high protection, NMT has revolutionarily redesigned the sealing structure, achieving excellent mud-water and salt-spray resistance while maintaining an ultra-low friction coefficient, ensuring the bearing is protected from external erosion in complex road conditions and significantly enhancing the overall reliability of the e-drive system.

In precision manufacturing and quality control, NMT enforces stringent standards for every component of its NEV bearings. Through ceramic hybrid materials, ultra-low friction design, and full-process quality control, the high-speed adaptability and energy efficiency performance of the bearings are comprehensively improved. NMT ensures that each bearing maintains an ultra-low temperature rise and ultra-low friction resistance under the extreme high-speed conditions of NEV e-drive systems, avoiding range degradation and premature failure, guaranteeing high consistency and high reliability of batch products, and completely eliminating operational hazards of new energy equipment.

With rich specifications, these bearings are widely used in pure electric and hybrid vehicle wheel hub bearing units, e-Axle coaxial reducers, drive motor spindles, and high-speed transmission nodes, satisfying the supporting needs of various low-friction, high-speed, long-life, and high-energy-efficiency transmission nodes.
