Proper installation and maintenance are crucial for maximizing slewing drive service life. According to industry manuals, mounting surfaces must have a flatness tolerance ≤0.1 mm/m to prevent bearing distortion . Bolt fastening requires a cross-pattern sequence at specified torques (e.g., 30% → 50% → 100% of final torque), using grade 8.8 or higher bolts to ensure structural stability .

Lubrication and sealing systems demand regular attention:

• Grease Selection: Mobil EP2 grease is standard for raceways and gears, with relubrication intervals adjusted based on operating cycles and environmental conditions .

• Seal Inspection: Multi-lip seals (e.g., NBR or FKM materials) should be checked for wear every 500–1,000 hours in abrasive environments like mining .

Predictive maintenance, including vibration analysis and oil debris monitoring, can preempt failures. For instance, rising temperatures or metallic particles in grease often signal gear wear or seal breaches .
