Whether the more grease is added to the tapered roller bearing, the better the lubrication effect. As you may know, the use of grease in bearings is very important. Then someone will ask, can the grease be used to lubricate the bearings indefinitely?

 When and how much oil should I change? In fact, these problems are complex problems of bearing maintenance technology.

    For the question of whether grease can be used indefinitely, the affirmative answer is impossible. Because of excessive use of grease, there are many hazards to 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 debris. Agglomeration with oil stains improves the mechanical wear resistance, pressure resistance and corrosion resistance.

   However, the greater the amount of grease filled, the greater the friction torque. With the same filling amount, the friction torque of sealed bearings is greater than that of open bearings. 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.
