What is the suitable viscosity of lubricating oil for the P2KA18 planetary reducer?

The viscosity of lubricating oil suitable for P2KA18 planetary gearbox is generally between ISO VG68-320, with ISO VG220 being the best. But the specific choice still needs to consider factors such as working conditions:

Temperature: If the ambient temperature is between -10 ℃ and 5 ℃, oil similar to Mobil Gear 626 (ISO VG88) can be selected; When the temperature is between 0 ℃ and 35 ℃, Mobil 627 or 629 (ISO VG100/150) can be considered; At 30 ℃ -50 ℃, Mobil Gear 630-634 (ISO VG220/460) is more suitable.

Speed and load: When the output shaft speed is above 100 revolutions per minute and the load is light, ISO VG150 lubricating oil can be used at ambient temperatures between 0 ℃ and 30 ℃; If the speed is below 100 revolutions per minute or under heavy load conditions, it is recommended to use lubricating oil with viscosity of ISO VG220 or higher to provide better wear resistance and oil film strength.

If you are unsure about the specific viscosity selection, you can refer to the product manual of the gearbox or consult the technical personnel of the gearbox manufacturer for more accurate advice.
