1. Correct lubricant selection
- The appropriate oil or grease should be selected based on bearing type, speed, load, and temperature.
- Synthetic oils and synthetic-based greases offer advantages at high speeds and temperatures.
- Oils with excessive EP additives or high-viscosity greases can shorten bearing life at high speeds.
2. Lubrication methods
a) Manual greasing
- Suitable for small bearings and low/medium speed motors.
- The amount of grease should not be excessive; it should fill 30–50% of the bearing's free space.
b) Centralized lubrication system
- Used in large systems with multiple bearings.
- Provides regular and controlled oil/grease supply.
- Lubrication intervals can be set automatically, preventing under or over-lubrication.
c) Drip or circulating lubrication
- Ideal for high-speed bearings.
- Oil circulates continuously, dissipating heat and cleaning.
- Extends life by maintaining a constant bearing temperature.
d) Oil bath (splash lubrication)
- Used in medium-speed and small bearings.
- The bearing is continuously in contact with oil, but it is not suitable for high speeds.
3. Lubrication interval and quantity
- Over-lubrication → overheating, friction, and energy loss.
- Insufficient lubrication → wear and premature bearing failure.
- Optimal quantity: Approximately 30–50% of the bearing's free space (for grease).
4. Other measures
- Using clean oil or grease, contamination severely shortens bearing life.
- Filtration and circulation to keep the oil clean.
- Regular monitoring of bearing temperature and oil changes if necessary.
- Vibration and load analysis to optimize lubrication intervals.
