Regular inspections of NSK bearings are important to maintaining NSK bearings in optimal condition and can also reveal problems. Regarding the matters and related knowledge that NSK bearings should be used in their use.
First of all, we want to emphasize that it is important to keep the NSK bearings lubricated and clean.
Therefore, before we inspect the NSK bearing, we should clean the surface of the NSK bearing and then remove the parts around the bearing. It should be noted that the oil seal is a very fragile part, so extra care should be taken during inspection and disassembly. Do not apply excessive force to avoid damage to the parts. Then carefully check the oil seal of the NSK bearing and its surrounding parts. If it has been shown to be a bad symptom, be sure to replace it. A bad oil seal will cause damage to the bearing, causing the NSK bearing to be cloudless and causing equipment downtime.
Second, we also check the lubricant of the NSK bearing.
Lubrication is very important, not only for NSK bearings, but also for all imported bearings. However, please note that it is not advisable to add too much grease to FAG bearings.
The inspection method for NSK bearing lubricant is:
Apply a little bit of lubricant to the two fingers. If there is any contaminant, feel it. Or apply a thin layer of lubricant on the back of the hand and check the seal.
Then it is to replace the lubricant of the NSK bearing.
NSK bearings lubricated with oil should be refilled with fresh oil and allowed to rotate at low speed for a few minutes if the old oil is drained. As much as possible, allow the oil to collect the contaminants from the wreckage and then vent the oil. Note: It is best to filter the oil before use.
For NSK bearings that use grease lubrication, the replacement of the grease should be avoided with a cotton joint to any part of the NSK bearing. Since these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings requires attention to this problem.
Finally, it is important to note that the exposed NSK bearings are covered.
When inspecting NSK bearings, never expose the bearings to contaminants or moisture. If the work is interrupted, the machine should be covered with a piece of oil-paper plastic or similar material.
