| Effect of grease on import bearings, can be said that the maintenance of imported bearing any is cannot do without grease, the grease Is it right? Better? Of course the answer is no, today to NACHI import bearings for example, explain to you. We know that plays an important role in the use of lubricating grease NACHI bearings, Is it right? More grease on bearing the better? In fact, grease too much actually has a lot of harm. Grease has good adhesion, abrasion resistance, temperature resistance, anti rust and lubrication, can improve the high temperature oxidation resistance, delay aging, can be dissolved carbon, prevent metal debris and oil binding, improving the corrosion resistance of mechanical wear resistance, pressure resistance and. Grease filling in the friction torque, the larger. Filling quantity of the same, the friction torque of sealed bearing is larger than that of the open NACHI bearing. After grease filling amount equivalent to 60% of the volume of the internal space of NACHI bearing, friction torque and no longer increases significantly. This is because of the open type grease in the bearing parts has been squeezed out, and the sealing grease type bearings have leakage. With the increasing amount of grease filled, NACHI bearing temperature rise linearly increased, filling the same, but higher than the open bearing sealed bearing temperature rise. Generally, grease sealed bearings filling amount, shall not exceed 50% of the internal space. Tests show that the Shawki and Mokhtar, ball bearing with 20% to 30% is the most suitable. |
