What Are The Functions of Insulating Coating Prepared on The Surface of Bearing Housing

The role of the insulating coating on the surface of the bearing housing is mainly to prevent current leakage and electrical corrosion, which is essential for the normal operation of many industrial equipment, especially those involving power transmission application scenarios. The following is a specific description of the action of the insulation coating:

1, to prevent current leakage: in the motor, generator, transformer and other equipment, the current may be conducted through the bearing for various reasons (such as fault current, stray current, etc.), resulting in energy loss and affecting the efficiency of the equipment. The insulating coating prevents the leakage of current from rotating parts (such as rotors) to stationary parts (such as bearing housings), maintaining the normal operation of the circuit.

2, prevent electrical corrosion: current leakage will lead to electrolytic reaction, and then cause the dissolution of the bearing surface metal, the so-called "electrical corrosion". Electrical corrosion will seriously affect the bearing capacity and service life, leading to equipment failure. The insulating coating can effectively isolate the current and avoid this destructive process.

3, protection bearing materials: bearings are mostly made of conductive materials such as steel, easy to be affected by current. The insulating coating can form a physical barrier on the bearing surface to protect the bearing from current erosion and extend its service life.

4, improve equipment reliability: By preventing current leakage and electrical corrosion, the insulation coating helps to reduce sudden failures, reduce maintenance and replacement costs, thereby improving the reliability and economic benefits of the overall equipment.

5, optimize equipment performance: For mechanical equipment, even small current leakage may affect control accuracy and performance. The application of insulating coatings can further optimize the performance parameters of the equipment, such as vibration level, noise control, etc.

6, adapt to the harsh environment: in a wet or dusty environment, the possibility of current leakage increases. The insulating coating provides additional protection, allowing the equipment to maintain stable operation even in harsh environments.

Bearing shell surface insulation coating is an important part of modern industrial equipment design and maintenance, its application can not only protect the bearing itself, but also improve the overall performance and safety of the equipment, is one of the key technologies to improve the efficiency of industrial production.
