When is the  suitable for  bearing add grease again  ?

The role of lubricating grease in the use of bearings is very important. Many people have asked, can I use lubricating grease to lubricate the bearing at any time ? At what period of time to change the grease , how much grease need add . In the process of bearing maintenance technology, these problems are indeed a bit complicated.

The answer to the question of whether the grease can be used freely and without restrictions,the answer is can't . because excessive use will damage the bearing. Grease has a good effect on bearings. It has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity. It can improve high temperature oxidation resistance, delay aging, dissolve carbon deposits, and prevent metal wear debris. Agglomeration with oil stains, improving the wear resistance, pressure resistance and corrosion resistance of the machine. But the more grease is filled, the greater the friction torque. With the same filling amount, the friction torque of the sealed bearing is greater than that of the open bearing. After the grease filling amount is equivalent to 60% of the internal volume of the bearing, the friction torque no longer increases significantly. This is because most of the grease in the open bearing has been squeezed out, and the grease in the sealed bearing has also been lost.

Generally, the lubrication of bearings is measured according to time. Most machine equipment manufacturers will make lubrication plans according to the operating time. And their measurement of lubricants is guided by the experience of the maintenance planning process, so it is common to change lubricants in the short term.

Lubricated bearings keep the equipment operating properly under conditions that do not stop due to dryness and collapse. However, we have to balance the need to lubricate hunger and a lot of excessive lubrication. If the oil change is too small, the bearing will be scrapped in advance; if the oil is changed too much, the bearing will be in trouble or will endanger the power coils and coils for a long time.

And we also can produce high temperature with adding high tempareture grease ,such as ,150 degree bearing ,200 degree bearing etc .
