The choice of NSK bearing, selected according to the size, accuracy of location and conditions of use and environmental conditions, with the appropriate NSK bearing is a prerequisite for NSK bearing life and reliability of the. To carrying capacity can reach NSK bearing, inner and outer rings of the bearing ( or thrust shaft bearing ring back ring ) the entire circumference, must be fully supported solid and uniform, the bearing surface can be surface cylindrical or conical, for bearing shaft ring and ring, with a smooth surface. Therefore, matched with the NSK bearing ring surface processing must reach a certain accuracy, and there should not be any grooves, holes or other discontinuous shape. In addition, the ring must be securely fixed, in order to prevent under load, bearing ring on its mating surface between the rotating.
1, using the site: joint load NSK bearings for radial and axial radial load to bear mainly on the NSK, usually with two sets of paired bearings use, mainly in the automotive front and rear wheels, a driving bevel gear, gear, reducer and other transmission parts.
2, allow the speed: correct installation, lubrication good environment, allowing for 0.3-0.5 times NSK bearing limit speed. Under normal circumstances the limit of 0.2 times the speed of the most desirable.
3, allow the tilt angle: NSK bearings are generally not allowed to tilt axis relative shell hole, if tilt, is less than 2′.
4, allow the temperature: under normal load and lubricant has the advantages of high temperature resistance performance and full lubrication conditions, general NSK bearing allows operation at -30℃ -150 ℃temperature environment.
NSK bearings continue to be removed after use, should choose the appropriate removal tool. Interference with the demolition of the rings, can only increase tension in the ring, must not be allowed to pass through the rolling force demolition, otherwise the roller and raceway will be crushed.
