5 Lubrication Ways for Mounted Unit Bearing

1. Drip Oil Lubrication

Drip oil lubrication is suitable for bearing components with  oil grease fitting that require a fixed amount of lubricant. Extra amount of oil will cause the temperature of the pedestal bearing to increase.

2, Circulating Oil Lubrication

Using the oil pump to offer the filtered oil to the bearing parts through housing, and then use the lubricating oil after the housing bearing to filter and cool. Because the circulating oil can take away a certain amount of heat and cool the bearing with a seat, this method is suitable for the bearing parts with a higher speed.

3. Oil Bath Lubrication

Oil bath lubrication is the most common lubrication method, suitable for the lubrication of low and medium speed housing bearings. A part of the housing bearings is immersed in the groove, and the lubricating oil is taken up by the rotating seated bearing parts, and then flows back to the oil groove oil. The face should be slightly below the center of the lowest rolling element.

4, Jet Lubrication

Using an oil pump, the high-pressure oil is injected into the bearing with the nozzle through the nozzle, and the other end of the bearing with the bearing is injected into the oil groove. When the housing bearing rotates at a high speed, the rolling element and the holding frame also form a flow of surrounding air at a relatively high rotation speed. It is difficult to send the lubricating oil to the housing bearing by the general lubrication method. The amount of oil dripping into the bearing with lubricating oil is generally one drop every 3-8 seconds. The position of the nozzle should be placed between the inner ring and the center of the frame.

5. Spray Lubrication

Dry compressed air is mixed with lubricating oil through a sprayer to form an oil mist. In the case of spraying a bearing with a seat, the airflow can effectively cool the bearing with a seat and prevent the intrusion of impurities. This method is suitable for high-speed, high-temperature lubrication of bearing components.
