The main reason that scar the outer spherical bearing are emerging in the process of the device is: NSK bearings are device, when assembling the emergence of inner and outer ring skew; maybe there are front load device and assembly process, eventually forming bearing emerge scar.
The outer spherical bearings are device according to standards, should not form many achievements, such as the way to form or not form bearing device when, have linear scar raceway and rolling surface will form the NSK bearing. Device for deep groove ball bearing indirect reaction with precision, life and function of the bearing use.
The outer spherical bearing quality are good, but the rolling bearings are precision components, its use must be carefully. No matter how high performance bearing, if used improperly, will not get the high performance expectations. Regarding the use of NSK bearing the matters needing attention were the following:
(1), keep the outer spherical bearing and the surrounding clean.
Even if is the eye cannot see small dust, will bring bad effect to the NSK bearings. So, to keep the surrounding clean, so that dust is not into the bearing.
(2) use, carefully.
Give the outer spherical bearing a strong impact in use, will have scars and indentation, became the cause of the accident. In severe cases, cracks, fracture, so be careful.
(3), using the right tools.
To avoid the existing tools instead, you must use the appropriate tool.
(4), attention should be paid to the spherical bearing corrosion.
When operating the NSK bearings, hand Khan will become the cause of rust. To note that the clean hands operation, the best to wear gloves.
Are bearing smooth range to run tasks. If the outer spherical bearing lose good smooth, and barrier sundry goods and eczema accurate, the oil seal Bian should not wear.
In order to prevent the outer spherical bearing is running process have destroyed, to form the facility downtime, loss. Therefore, in response to the monitoring task of bearing.
In order to prevent the emergence of NSK bearings are device scars, unless the proper use of machines are devices or assembly process, but also to use punch prevention for front load bearing, moreover must pay attention to is the mutual centering device.
