Oil bath lubrication: Oil bath lubrication is the most common lubrication method, suitable for lubrication of low and medium speed bearings. A part of the bearing is immersed in the oil tank, and the lubricating oil is carried by the rotating bearing parts and then flows back to the oil tank. The oil level should be slightly lower than the center of the lowest rolling element.
Oil dripping lubrication: Oil dripping lubrication is suitable for bearing parts that need to be quantitatively supplied with lubricating oil. The amount of oil dripping is generally one drop every 3-8 seconds. Excessive oil will cause the bearing temperature to increase.
Circulating oil lubrication: Use an oil pump to transport the filtered oil to the bearing parts. The lubricating oil after passing through the bearing is filtered and cooled before use. Since the circulating oil can take away a certain amount of heat and cool the bearing, this method is suitable for bearing parts with higher speeds.
Spray lubrication: Use dry compressed air to mix with lubricating oil through a sprayer to form oil mist, and spray it into the bearing. The airflow can effectively cool the bearing and prevent impurities from invading. This method is suitable for the lubrication of high-speed and high-temperature bearing parts.
Spray lubrication: Use an oil pump to spray high-pressure oil into the bearing through a nozzle, and the oil injected into the bearing flows into the oil tank through the other end of the bearing. When the bearing rotates at high speed, the rolling elements and the cage also rotate at a very high speed, causing the surrounding air to form an airflow. It is difficult to deliver the lubricating oil to the bearing using general lubrication methods. At this time, the lubricating oil must be sprayed into the bearing using a high-pressure jet. The nozzle should be placed between the inner ring and the center of the cage.
