Bearing grease (commonly known as yellow oil, dry oil, butter, etc.), a gel-volt lubricating materials. Bearing lubrication is widely used. Its advantage is that the grease is easy to maintain in the bearing, not leak, easy maintenance, t o prevent moisture, dust and other harmful impurities immersed in oil high strength, you can use a longer period not to replace. But speed is high, friction losses, the thrust angular contact ball bearing temperature increased. Grease for speed and temperature conditions. In the selection of grease, to take into account the following aspects:ball roller bearing
The rotation speed of the bearing according to the speed of decision, the higher the speed, should choose the greater penetration of grease.
Imports bearing load bearing load size, load the greater the smaller the penetration of grease should be selected. Increase in the film, under pressure to fill grease to withstand heavy-duty bearings should be selected to join.bearing roller bearings
Chosen by the bearing operating temperature in accordance with the normal operating temperature of the bearing grease, grease dropping point temperature lower than 10 ^ -20 `C. Overflow of bearing work for the use of synthetic grease should be less than the drop point 20-30 C to.
Bearing the surrounding environment in accordance with dirt and other conditions to select the Wet fat.
Based on the above aspects, when the imported bearings in the fuel is not easy to achieve, and the adverse external environment, while the number of revolutions does not exceed 4-5 m / s, the general use grease to lubricate.roll bearings
