Bearing for idler commonly used lubricants have two kinds of lubricating oil and grease.
When the circumferential velocity is less than 4-5m/s, or the car can not use lubricating parts are lubricated by grease. Two problems should be paid attention to when using grease, one is to choose the suitable grease according to the requirements of the automobile instructions. Two is to add the grease in the bearing should be appropriate, generally only filling the bearing cavity 1/2-l/3 is appropriate, too much is not only useless, but also increase the bearing running resistance, so that heating, heating.
Lubricating oil has the advantages of small friction resistance and heat dissipation. It is mainly used in high speed and high temperature working environment bearings. The lubricating oil grade should be selected according to the requirements of the automobile manual, and the automobile maintenance cycle should be replaced in time. After the old oil is released, the new oil should be added after the cleaning, and the refueling should be added to the prescribed marking or even with the fuel port.
