Spherical roller bearing manufacturers explained to the technical staff on a regular basis for self-aligning roller bearings, for the maintenance of self-aligning roller bearings in the best condition is very important work, can also reflect the problem. The following technical staff gave you to share some of the self-aligning roller bearings for regular inspection of some methods.
First, it is important to keep the self-aligning roller bearing lubricated and clean.
When inspecting a self-aligning roller bearing, you should clean the surface of the self-aligning roller bearing and then remove the parts around the bearing. We should note that the oil seal is very fragile parts, so check and dismantling the need for extra care, do not over-force, so as not to cause damage to parts. And then carefully check the self-aligning roller bearing oil seal and its surrounding parts, if it has been showing adverse symptoms, be sure to replace the bad oil seal will lead to bearing damage to the spherical roller bearing cloud is not normal Resulting in equipment downtime.
Second, check the self-aligning roller bearing lubricant.
Lubrication is very important, not only for the self-aligning roller bearings, but also for all imported bearings. On the self-aligning roller bearing lubricant inspection methods:
Stained with little lubricant in the friction between the two fingers, if contaminants exist, can be felt out; or in the back of the hand coated with a thin layer of lubricant, and then sealed light inspection.
Then replace the spherical roller bearing lubricant.
Use oil-lubricated self-aligning roller bearings After purging old oil, refill fresh oil and allow the machine to spin for a few minutes at low speed if possible. As much as possible, allow the oil to collect the remaining contaminants, and then diarrhea in addition to these oils. Note: oil is best filtered before use.
And the use of grease-lubricated self-aligning roller bearings in the replacement of grease, the use of Joe in addition to the device should be avoided with a cotton material angle to aligning roller bearings of any part. Because these residual fibers may wedge between the rolling elements and cause damage, especially the application of small bearings need to pay more attention to this problem.
Finally, it should be noted that the coverage of the exposed spherical roller bearings.
When checking self-aligning roller bearings, do not expose bearings to contaminants or moisture. If the work is interrupted, the machine should be covered with oil-paper plastic sheet or similar material.
If unmasked bearings are to be cleaned without the need for disassembly and inspection, brush the coating with petroleum solvent and wipe dry with a lint-free cloth or dry with compressed air (be careful not to let Bearing assembly starting rotation).
Check the track surface, retainer, and bead of the bearing with a small mirror and the same type of probe used by the dentist. If the bearings are not damaged, relubrication should be carried out in accordance with the lubrication instructions provided by the machine manufacturer.
Do not clean the sealed cover or dust-proof bearing; only wipe the external surface. If the bearing is damaged when the need to be replaced. Replacing the bearings during a regular outage period is far more costly than the loss of a sudden stop caused by bearing damage.
