NSK bearing used environments: according to site conditions and conditions of use and the environment dimension, precision, combined with suitable bearing is a prerequisite to guarantee bearing service life and reliability.
Used parts: bearings are suitable to withstand radial load-oriented combination of radial and axial load, usually with two sets of paired bearings used, mainly in the car′s front and rear wheels, active cone transmission parts such as gears, differentials, gearbox.
Allowed speed: installed properly, lubrication good environment, allowing for NSK bearing limit rotational speed of 0.3 per cent. Under normal circumstances, to 0.2 times the speed limit for the most desirable.
Allows tilt angle: bearings are generally not allowed to tilt axis relative shell holes, such as tilt, maximum of 2 ′.
Allowable temperature: under normal load, and with high temperature performance of lubricants and lubrication under adequate conditions, NSK bearings generally allow at-30 ° c-150 ° c ambient temperature.
How to ensure the NSK bearings are used in the course of normal, how to make bearings without injury to longer bearing life.
1, selection and control of shaft and housing tolerances: after bearing pressed into the bearing should be sense of rotating flexible non-blocking. Subject to obvious turn flexible, the size is too big for that axis, the tolerance to cut.
2, bearing Assembly methods: NSK bearings are high-precision products, such as improper Assembly can easily cause damage to the bearing Raceway, cause damage to the bearing.
3, rigging, prevent foreign bodies: NSK bearings are mounted to the rotor dynamic balance is easy when you will enter the bearing dynamic balancing produced when iron filings, it is best that you did before loading bearing dynamic balancing.
4 Prevention of rust, paint: paint the rust is characterized by multiple sealed-type motor, motor Assembly has a good voice, but after you put some time in the warehouse, abnormal sound of motor and remove the bearing with serious rust.
NSK bearings are in the process of checking if there are too many problems, as well as these bearings are bearings can be faked. Is a reminder at the selected time must be careful.
