NSK bearings are commonly used lubricant oil and grease in two ways. When the circumference of the shaft speed is less than 4-5M/s, or parts of vehicle lubricating oil cannot be used on are using grease lubrication. Grease-lubricated seals are the advantages of simple structure, loss of grease is not easy, is not affected by the temperature, add lubricating grease once you can use a long period of time.
Use grease should pay attention to two issues, is to cars manual requirements, selection of appropriate grades of lubricating grease. For example, selection Naki grease automobile water pump bearings, it would not be appropriate, because of its poor water resistance. B is joined in NSK bearing grease to amount, generally fill bearing cavity 1/2-l/3, too much is not only useless, also increases the running resistance of bearing, warming heat. Special attention is the wheel bearing, promotion of "air hub lubrication", that is, apply a layer of the right amount of grease in the bearings, otherwise wasted and poor cooling and heating makes grease spills that might affect braking performance.
Advantage of friction resistance of lubricating and cooling, mainly for NSK bearing for high-speed and high ambient temperature. Requires selection of grades of lubricating oil to cars manual and auto maintenance replacement in a timely manner, and released after the old oil to cleaning your body, and then add the new oil, fuel should be added to the prescribed marking, or flush with filler (as the vehicle specific structures, requirements may be), not more.
