Theoretically centrifugal pump service grinding spindle life of rolling bearings NSK 20,000 to 80,000 hours, however, the actual life depends on many factors - NSK Bearings premature failure will lead to consideration of the high equipment downtime, and sometimes even lead more serious consequences. NKE (Austria) company NSK Bearings expert provides some simple but practical NSK Bearings performance optimization techniques.
Satisfactory life begins NSK Bearings NSK Bearings correct choice. From the outset, NSK bearings for different applications through designers select the right NSK Bearings NSK Bearings to extend equipment life and performance. This process should consider many factors, such as load, hardness, NSK bearings life prediction, operating environment and so on.
Correct storage
In principle, all NSK bearings prior to installation fatigue testing machine should be kept in their original packaging. They need to stay in a clean, moisture free, relatively constant temperature in the environment. Rolling NSK Bearings should stay away from dust, water and corrosive chemicals. Shaking and vibration may forever destroy the mechanical properties of NSK bearings, so the handling and storage process must avoid vibration.
Basically, all levels of NSK bearings have to be saved, because some heavier NSK Bearings long vertically, it may be deformed due to its own weight.
Pre-coated with grease (or sealed) NSK bearings need to be careful, because the oil after a long period of storage after the density change. NSK bearings so that when the first time, there will be a certain degree of rotation noise. Thus, the NSK bearings aside time should be controlled according to the FIFO principle.
Clean
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.
