Bearing grease (commonly known as yellowish oil, dry oil, butter, etc.) is a kind of gel lubricating material. It is widely used in bearing lubrication. Its advantage is that the grease is easy to keep in INA Bearing, not easy to leak, simple maintenance, can prevent the immersion of moisture,
dust and other harmful impurities, and the grease has high strength. It can be used for a long time without replacement. However, when the Ina Thrust Angular Contact Ball Bearing rotating speed is high, the friction loss is large, which increases the temperature of thrust angular contact ball bearing.
The grease is suitable for use under general speed and temperature conditions. When selecting Ina Thrust Angular Contact Ball Bearing lubricating grease, the following aspects should be considered:
1. The rotation speed of the bearing is determined by the rotating speed. The higher the rotating speed, the greater the penetration of the grease should be selected.
2. The load of the imported bearing is based on the load of the bearing. Ina Thrust Angular Contact Ball Bearing The greater the load, the smaller the penetration should be selected. For ina bearings bearing heavy load, grease with increased oil film and compressive capacity shall be added.
3. The working temperature of the bearing shall be selected according to the normal working temperature of the bearing,
and the lubricating grease shall be Ina Thrust Angular Contact Ball Bearing 10 ^ – 20 ` C lower than the dropping point temperature of the lubricating grease. When using synthetic grease, the working overflow of the bearing should be 20-30’c lower than the dropping point.
4. The surrounding environment of the bearing shall be lubricated Ina Thrust Angular Contact Ball Bearing according to the degree of dirt and other conditions.
and the external working environment is poor, and the Ina Thrust Angular Contact Ball Bearing number of revolutions does not exceed 4-5 M / s, grease is generally used for lubrication.
In principle, the lubrication of the bearing is basically the same as that of other dynamic thrust angular contact ball bearings, but the working premise of the bearing is relatively poor. Whether its working function can be effectively applied depends on the lubrication of the bearing to a great extent.
The lubrication methods of bearings mainly include grease lubrication and oil lubrication.
The grease of grease lubrication has the function of sealing. The Ina Thrust Angular Contact Ball Bearing sealing structure and lubrication measures are simple and convenient. Therefore, as long as the working premise is allowed, the bearings are generally lubricated with grease.
Oil lubrication has strong cooling effect and can take away dirt and moisture from ina bearing. Imported bearings are lubricated by oil, including pressure oil supply lubrication, oil injection lubrication, oil mist lubrication and oil-gas lubrication.
Pressure oil supply lubrication is an effective way of bearing lubrication at conventional speed.
Oil injection lubrication is to inject lubricating oil into the bearing through the oil injection nozzle installed on one side of INA Bearing at a certain pressure for lubrication. It is generally used in high-speed bearings or occasions where pressure oil supply lubrication cannot meet the cooling requirements.
Spray lubrication is to spray dry compressed air containing oil mist into the thrust angle contact ball Ina Thrust Angular Contact Ball Bearing bearings to lubricate, use less oil, and because of the effect of air, the cooling effect is very strong.
It is mainly used for large bearings with high rolling speed and high rolling accuracy, or bearings which are not often dismantled in the INA bearing box.
Both pressure oil supply lubrication and oil injection lubrication need to be equipped with oil inlet and outlet pipes, lubrication pumps, oil reservoirs, and sometimes lubricating oil coolers. Therefore, the cost is high and the general bearings are rarely used.
