High-speed, low-noise bearings for next-generation mobility
Application Overview
The automotive industry is undergoing rapid electrification, creating new bearing challenges for EV motors, power electronics cooling, ADAS sensors, and autonomous driving systems. SKDIN deep groove ball bearings and angular contact bearings are optimized for high-speed EV motor applications, while our miniature bearings serve LIDAR, radar, and camera gimbal systems.
Key Engineering Challenges
- High-speed EV motor operation (20,000–30,000 RPM)
- Electrical erosion from inverter-induced currents
- Low noise for cabin comfort in EVs
- Compact packaging for weight reduction
- Long service life matching vehicle lifetime
