Product Note: Lubricant Replacement Interval for Spur Gear Slew Drives

The lubricant replacement interval of Spur Gear Slew Drives is determined by operating conditions, workload intensity, and environmental factors, with the following recommended guidelines for stable performance:
Normal Operating ConditionsFor standard industrial scenarios (temperature between -30°C and 50°C, medium load, 8-hour daily operation, and clean working environment), lubricant replacement is recommended every 6–12 months or after 2,000–3,000 operating hours, whichever comes first. This interval ensures that the gear meshing surface remains well-lubricated, reducing wear and maintaining transmission efficiency.
Harsh Operating ConditionsIn extreme environments (frequent temperature fluctuations, high dust, heavy load, or continuous 24-hour operation), the lubricant is prone to accelerated oxidation and contamination. Under such circumstances, shorten the replacement cycle to every 3–6 months or after 1,000–1,500 operating hours. Timely replacement can prevent lubricant failure, avoid gear corrosion and premature wear, and extend the service life of the drive.
Lubricant Selection ReminderAlways match the lubricant type to the actual working temperature: choose low-temperature resistant lubricants for sub-zero environments to ensure fluidity, and high-temperature lubricants for high-heat conditions to prevent viscosity loss.
