Under the bearing if you did not select the error correctly used, before the NSK bearing service life, can be used for a long period of time. The other hand, there are accidents of injury early, early injuries and stand, as the reasons for early damage, consider not enough lubrication, turn, intrusion of foreign bodies, bearing Assembly error and the deflection of the shaft, shaft and housing research is not enough. It can be said that for these reasons coincide with each other more.
Decide when lubricated and when to stop oil ways are very simple: develop a base line, making observation schedule and monitor when oiling.
NSK bearings when you intend to continue using after you removed, you should use the appropriate removal tool. Demolition of the interference rings, tension can only be added on in the ring, would never allow passing demolition by rolling or rolling element and the Raceway will be crushed.
According to the location and conditions of use and environmental conditions select size, accuracy, combined with suitable bearings NSK bearings are guaranteed long life and reliability of the premise.
1, the use of site: NSK bearings are suitable to withstand radial load-oriented combination of radial and axial load, usually with two sets of paired bearings, mainly on the front and rear wheels of the car, the active cone transmission parts such as gears, differentials, gearbox.
2, allows speed: correctly installed, lubrication good environment, allow for bearing limit rotational speed of 0.3 per cent. Under normal circumstances, to 0.2 times the speed limit for the most desirable.
3, allowing tilting angle: tapered roller bearings are generally not allowed to tilt axis relative to the shell holes, such as tilt, maximum not more than 2 ′.
4, the allowable temperature: under normal load and high temperature performance of lubricants and lubrication under adequate conditions, General bearings allow at-30 ° c-150 ° c ambient temperature.
Therefore, machines to be used in full understanding of NSK bearings, conditions of use, bearing peripheral structures on the basis of, if we can understand the situation before and after the accident, coupled with bearing and multiple causes of injury visits, you can prevent the recurrence of similar incidents.
