First and foremost; what we should focus on is that it is important to keep the NSK bearings smooth and clean. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
So before we look at the NSK bearing; we should lead the appearance of the sanitary NSK bearing; then disassemble the parts around the bearing. We must pay attention; the oil seal is a very weak part; therefore, the need for attention when looking at and disassembling; Do not apply excessive force; prevent damage to the parts. Then carefully check the oil seal of the NSK bearing and its surrounding parts; if it has shown poor performance; it must be replaced; poor oil seal will cause damage to the bearing; make NSK The bearing cloud is not normal and the device stops.
Secondly; we also need to look at the smoothing agent of NSK bearings.
Smoothness is very important; not only NSK bearings; but also all imported bearings. But please pay attention; FAG bearings should not add too much smooth grease.
The way to view NSK bearing smoothing agents is:
Apply a little smoothing agent to the conflict between the two fingers; if there is a contaminant; feel it, or apply a thin layer of smoothing agent on the back of the hand; then seal it.
Then it is to replace the smoothing agent of NSK bearing.
Use oil-smooth NSK bearings to remove old oil; if possible; fresh oil should be refilled and the machine rotated at low speed for a few minutes. The oil can be used to collect residual contaminants; then diarrhea These oils. Focus: the oil is best filtered before use.
The use of grease smooth NSK bearings in the replacement of grease; the use of the cutter should prevent the cotton joints to any part of the NSK bearing. Because these residual fibers can be wedged between the rolling elements And the formation of damage; especially the use of small bearings need to pay attention to this problem.
Ultimately; demand is focused on covering the exposed NSK bearings.
When viewing NSK bearings; do not expose the bearings to contaminants or moisture. If the work is stopped, cover the machine with oil-paper plastic sheets or similar materials.
If the unshielded bearing is removed without being disassembled and can be viewed; remove it with a white spirit by applying a brush; then dry it with a lint-free cloth or blow it with compressed air. Dry (pay attention not to let the bearing assembly start to rotate).
Use a small mirror and a probe used by a similar dentist to view the track surface of the bearing, the holder and the beads. If the bearing is not damaged, it should be based on the smooth explanation provided by the original machine or on pages 204 to 247 of this book. The claim is fulfilled again.
It is not necessary to remove the bearing with the sealing cover or dustproof, only scrub the external appearance. If the bearing is damaged, it needs to be replaced. The replacement of the bearing during the timed protection period is far better than that due to the damage of the array. It’s more economical to lose it.
