However, in the maintenance or replacement work

Clean the rolling NSK bearings is very important. NSK Bearing ring rolling surface and the rolling elements of the surface roughness is typically 1/10 μm, such a smooth surface of pollutants are very sensitive to damage. A lubricating layer between the rotating surface is generally 0.2 ~ 1 μm, a particle size larger than the lubricant-type impurity will be rolled over the rolling element bearings in the NSK partial pressure produced in steel, fatigue will eventually cause permanent. In addition to this, the external environment in the dust particle size of up to 10 μm, NSK bearings will also cause damage. Therefore, clean dust-free environment for NSK Bearings storage and installation is critical.
????Fully prepared to install
NSK Bearings should carefully using a suitable tool installation and removal. Industry experts estimate that premature failure of NSK Bearings 16 percent of cases are due to incorrect installation. For large installations (for example in the production of the device) is concerned, usually installed strictly controlled conditions, you can use the appropriate NSK bearings installed equipment.
However, in the maintenance or replacement work, the environment is varied. Therefore, to ensure the longest life of NSK ball bearing manufacturer, comprehensive preparatory work on NSK Bearings installation is necessary.
First, the relevant documents, such as drawings, maintenance manuals, brochures and other products require careful study. Next, all NSK Bearings components, such as shafts, the distance ring, cover, washers, etc. must be kept absolutely clean and free from contamination. Adjacent parts of the state should be carefully examined.
Careful installation and removal
According to the different applications and NSK crossed roller bearing size and type, choose the appropriate installation method (mechanical or hydraulic) and tools. Here is the NSK bearings installed some basic principles:
1 Do not install the force applied to the rolling elements, which can easily lead to the rolling element and the contact surface of the seat of local overload, leading to premature failure of NSK bearings.
(2) Do not use any hard tools (such as hammers, screwdrivers, etc.) directly to knock on the surface of the NSK bearings, NSK bearings which can cause breakage or fragmentation rings.
