1. Precise Selection of Grease
- Use lithium‑based or composite lithium greases with water resistance, oxidation resistance, and extreme‑pressure anti‑wear properties.
- For high‑temperature drive bearings, consider high‑temperature resistant special greases.
- Ensures stable oil film formation under extreme conditions, reducing direct metal‑to‑metal friction.
2. Reasonable Planning of Lubrication Cycles
- Formulate lubrication schedule based on equipment usage frequency, environment, and bearing model.
- Shorten intervals under continuous high‑intensity operation or dusty conditions.
- Avoid over‑greasing – excessive grease hinders heat dissipation and may cause overheating or burnout.
3. Regular Cleaning of Bearing Housings
- Thoroughly drain waste grease from the housing before adding new grease.
- Use drain holes or remove end covers; flush with cleaning agent if necessary.
- Clean housing ensures new grease lubricates effectively and extends bearing lifespan.
4. Dynamic Monitoring of Operating Conditions
- Regularly check bearing housing surface temperature with an infrared thermometer.
- Use a listening rod to assess internal bearing sounds.
- Abnormal temperature spikes or metallic noises indicate poor lubrication or wear – stop immediately for inspection.
