To maintain smooth operation and prolong the service life of a slewing bearing, regular greasing is essential. Here's the correct method and important precautions:
Greasing Method:
1. Use a manual or electric grease gun to inject grease into the raceway through the grease nipple.
2. Slowly rotate the slewing bearing during the process to ensure even grease distribution.
3. Stop when you see grease being slightly extruded from the seals - this indicates sufficient lubrication.
Precautions:
• Always use the manufacturer-recommended grease type and clean the grease fittings before use.
• Never mix different types of grease, as it may cause chemical reactions or reduce lubrication efficiency.
• In high- or low-temperature environments, use specialized grease designed for such conditions.
• It's recommended to re-grease every 100 operating hours or every 3–6 months.
