Under normal circumstances, the general corporate procurement NSK Bearings will have excess inventory, storage place will lead to unreasonable NSK bearing failure deformation. NSK Bearings reasonable storage place is a very important task.
In principle, all NSK bearings before installation should kept in their original packaging. They need to stay in a clean, moisture free, relatively constant temperature environment. Aligning ball bearings should be kept away from dust, water and corrosive chemicals. Shaking and vibration may never will damage the mechanical properties of NSK Bearings in the process of handling and storage must avoid vibration.
Basically, all NSK Bearings must be level to save some heavier-aligning ball bearings for a long time after the vertical placement may be deformed due to its own weight.
Pre-coated with grease (or seal) NSK bearings need to be especially careful, because the oil will change after a long period of storage density. So that when the bearing for the first time use, there will be some degree of rotational noise. Therefore, this bearing set aside time to control a FIFO basis.
(1) location in the right decision axis in the radial direction and axial direction at the same time, inhibition of the axis of the beating.
(2) increase the rigidity of the bearing. Aligning ball bearings, the machine tool spindle, cycling differential, pinion bearings.
(3) to prevent the axial direction of vibration and abnormal noise caused as a result of the resonance. Small motor bearings.
Under the combination load of radial bearings withstand the load rolling element number increased, the frictional resistance increases, the fever increased in poor lubrication and cooling conditions, and acting on the cage force also increases, therefore, must be based on the size of the NSK bearing type and load angle, aligning ball bearings, the speed limit multiplied by a lower coefficient of f2 to swap.
If the selected speed limit speed of the NSK Bearings can not be satisfied with the application requirements, we can use some improvement skills approach to be progress, to reach more to meet the request. Such as raising the level of self-aligning ball bearings tolerance; appropriate to increase the clearance; switch to special information and improved to adhere to the frame structure; change the method of lubrication, such as taking oil and gas, oil mist with spray lubrication; improved cooling conditions.
