NSK bearing two commonly used lubricant oil and grease. When the circumference of the shaft when the speed is less than 4-5m/s, or car parts are lubricated by 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, you can add lubricating grease once used a long time.
Use grease should pay attention to two issues, one is to press the car specification of requirements, selection of appropriate grade of grease. For example, a car water pump bearing selection m. Mounir Bouchenaki grease would be inappropriate, because of its poor water resistance. B is to add the grease in the bearing to just the right amount, generally filling bearing cavity 1/2-l/3, too much is not only useless, but also increases the running resistance of NSK bearings, to warming fever. Note bearing in particular, promotion of "air hub lubrication", that is, only you can apply a layer of the right amount of grease in the bearing, otherwise, is not only a waste and poor heat, also putting grease heated spills that may affect braking performance.
Lubricating the advantage of friction resistance is small, and thermal, mainly used in high-speed and high ambient temperature of NSK bearings. Grades according to the specification of a car requires selection of lubricating oil, and timely replacement of car maintenance cycle, release old oil to clean the body and then add the new oil, oiling should be added to the prescribed marking, or flush with filler (as the car specific structure, requirements may be), not more.
Full account of NSK bearing fatigue life, rigidity, fever, and other factors, select the most appropriate bearing clearance (preload).
Due to the bearing internal clearance and preload on performance of NSK bearings are the most critical, the more high-speed operation is the key, so you must carefully consider. When a poor choice, early damage or sintering problems can also occur.
After you determine the spindle structure design, taking into account the actual installation of the necessary conditions.
Installation of high-precision bearings for precision, tolerances for shafts and housings fit, required to install fixed fixing nut tightening force, the actual installation of NSK bearing internal clearance and preload after confirmation.
