Kit de roulement céramique du rotor d’unité d’entraînement pour

This kit provides a reliable solution to a common issue in the first-generation BMW i3 e-axle motors.

Factory bearings typically fail after around 120,000 km due to electrical current passage through the bearing.

With this kit, you can replace the damaged bearings instead of replacing the entire e-axle or motor — saving time and cost.

The hybrid ceramic deep groove ball bearings feature:

• Bearing steel rings and silicon nitride rolling elements – providing electrical insulation and eliminating current-related damage.

• Sealed design – keeps lubricant in and contaminants out, extending bearing service life.

• Enhanced performance – higher speed capability, greater stiffness, superior wear resistance, and better temperature stability compared to standard steel bearings.

Key Benefits:

• Prevents electric current damage

• Longer bearing service life

• Reliable operation in harsh or contaminated environments

• Ideal upgrade for professional repair and rebuild applications
