Product Description

2000N EV Motor Ceramic Si3N4 Silicon Nitride Balls For Electric Vehicle Bearings

Superior Performance for Electric Vehicle Applications

Silicon nitride (Si3N4) ceramic balls represent a breakthrough in bearing technology for electric vehicles, offering unmatched durability, efficiency, and reliability in demanding EV motor applications.

Key Advantages of Silicon Nitride Ceramic Balls

Electrical Insulation: Prevents electrical arcing and bearing damage from charge buildup
Reduced Friction: Ultra-smooth surface minimizes energy loss and extends lubrication intervals
Lightweight Construction: 60% lighter than steel for improved vehicle efficiency
Extreme Durability: Maintains performance under shock loads and harsh conditions
Corrosion Resistance: Withstands aggressive environments and chemicals
High-Temperature Stability: Performs reliably in extreme heat applications
