Oil Seal Usage Guide:

① When the lubricating oil volume of the gearbox is ≤ 7 liters, the amount of lubricating oil added per liter is 20-30ml;
② When 7-15 liters, the amount added is 15-20ml per liter of lubricating oil;
③ When the volume exceeds 15 liters, add 10ml of lubricating oil per liter;
7. Temporarily unused oil seals should be properly stored to prevent contamination with oil, dust, or direct sunlight.
8. When the shaft diameter is worn into a V-shaped groove, causing a decrease in the contact pressure between the new oil seal lip and the shaft, which cannot seal the oil, displacement can be used to compensate for it
