Polyurea greases for electric fan motor bearings
3 min read | 20 April 2023
Polyurea greases are indeed a suitable lubricant for electric fan motor bearings due to their unique properties. Here’s why they are favoured for electric fan motors and how they are typically applied:
Advantages for Electric Fan Motors:
- Temperature Stability: Electric fan motors, although not generating excessive heat, can benefit from the high-temperature stability of polyurea greases, maintaining their performance over a broad temperature range.
- Long Service Life: Polyurea greases typically have a longer life compared to other grease types, reducing the need for frequent re-lubrication and maintenance.
- Oxidation Resistance: They resist oxidation, maintaining their lubricating properties and preventing deposit formations, which is crucial for the longevity of the fan motor.
- Noise and Vibration Reduction: Proper lubrication with polyurea greases can minimise noise and vibration, ensuring smooth operation of the fan.
- Moisture Resistance: Polyurea greases are also resistant to water washout, which can be beneficial in humid conditions or when the fan is exposed to moisture.
Application:
- Initial Lubrication: Electric fan motor bearings are usually lubricated with polyurea grease during assembly. The right amount of grease should be applied to avoid over-greasing.
- Re-lubrication: Although polyurea greases have a long service life, regular checks should be made, and re-lubrication should be performed as needed, especially for fans operating continuously or under harsh conditions.
- Maintenance: Regular cleaning and inspection of the bearings are also essential to detect any wear and tear or contamination early and to ensure the grease is still effective.
Polyurea grease, due to its high-temperature stability, oxidation resistance, long service life, and other superior properties, is an excellent lubrication choice for electric fan motor bearings, ensuring their smooth and efficient operation while minimising wear and tear, noise, and vibration. The selection of the appropriate grease and regular maintenance are essential for optimising the performance and extending the lifespan of the electric fan motors.
