Product Details
The silicon carbide sleeve is mainly used to protect the motor shaft or related rotating parts, reduce friction and wear, and improve the efficiency and life of the motor. Due to its high hardness and wear resistance, silicon carbide bushings can withstand operation under high loads and high temperature environments while maintaining stable performance.
The silicon carbide sleeve also has excellent thermal conductivity, which can effectively transfer the heat inside the motor and maintain the stable operation of the motor.
