What are Lubrication Methods of Tapered Roller Bearings

Tapered roller bearings generally need to be lubricated during use, but for bearings that need lubrication, many people will ask what are the ways to lubricate the bearings? What are the bearing lubrication methods? Based on the summary, Wuxi Spark Bearing Co., Ltd tells everyone that there are 9 main ways to lubricate bearings.

1. Manual lubrication

This is the most primitive method. When the lubricating oil of the tapered roller bearing is insufficient, use an oiler to supply oil. However, this method is difficult to maintain a certain amount of oil. It is more dangerous to forget to refuel due to negligence. It is usually only used in light-load, low-speed or intermittent sports. When it is best to operate, install a dust cover or ball valve on the refueling hole. And use felt, cotton, wool etc. as filter device.

2. Oil ring lubrication

The lubricating oil from the oil sump is brought to the bearing by the ring that is hung on the shaft and can rotate (only for the lubrication method of the horizontal shaft). It is suitable for medium-speed and high-speed bearings with a shaft diameter greater than 50mm. The oil ring is best Seamless, when the bearing width-to-diameter ratio is less than 2, only one oil ring can be used, otherwise two oil rings are required.

3. Oil rope lubrication

Relying on the capillary and siphon action of the oil rope to guide the lubricating oil in the oil cup to the tapered roller bearing, it is mainly used for light load and medium load bearings with a peripheral speed of less than 4～5m/s. In addition, the oil rope can be used in the whole process. Play a filtering role.

4. Oil pad lubrication

Using the capillary action of the oil cushion, the lubricating oil in the oil pool is applied to the surface of the shaft diameter. This method can keep the friction surface clean, but dust will also block the pores and cause insufficient oil supply. The oil supply of oil pad lubrication is usually only 1/20 of oil lubrication.

5. Splash lubrication

The lubricating oil splashed by the rotating parts in the oil tank is supplied to the bearing. Need bearing WSBC LM742749/LM742710, please click here learn more.

6. Spray lubrication

Lubrication method in which the lubricating oil is sprayed on the friction surface after atomization.

7. Pressure lubrication

Relying on the pressure of the lubrication pump to supply oil to the bearing, and to recover the lubricating oil flowing out of the bearing to the oil pool for recycling. It is the most stable and stable lubrication method for high-speed, heavy-duty and important tapered roller bearings. .

8. Circulating oil lubrication

The oil pump is used to transport the filtered oil to the bearing parts, and the lubricating oil after passing through the bearing is filtered and cooled for use. Since circulating oil can take away a certain amount of heat and cool the bearing, this method is suitable for tapered roller bearing components with higher speeds.

9. Jet lubrication

The high-pressure oil is injected into the tapered roller bearing through the nozzle with an oil pump, and the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at a high speed, the rolling elements and the cage also make the surrounding air form an air flow at a relatively high rotation speed. It is difficult to send the lubricating oil to the bearing by the general lubrication method. At this time, the lubricating oil must be sprayed by high-pressure injection. In the bearing, the position of the nozzle should be placed between the inner ring and the center of the cage.
