When we double row tapered roller bearings before they are inspected, you should clean the surface of FAG Bearings, and then remove the parts around the bearing. It should be noted that the seal is very fragile parts, so need to be extra careful inspection and disassembly, do not use excessive force, so as to avoid damage to the parts. Then carefully check the double row tapered roller bearing oil seal and the surrounding parts have shown adverse symptoms, be sure to replace the lost, poor seal can cause damage to the bearings, bearing cloud is not normal and cause the device to downtime.
Lubrication is very important, not only for double-row tapered roller bearings, but also for all bearings. However, note that and FAG bearings should not add too much grease.
On the inspection method of the bearing lubricant is:
Stained little lubricant friction between two fingers, if contaminants exist, feel it; or coated with a thin layer of lubricant on the back of the hand, and then seal-ray examination.
Using oil lubricated double row tapered roller bearings in diarrhea in addition to the old oil, If you can, should and then poured into the fresh oil and let the machine a few minutes at low speed rotation. The oil as much as possible to collect residual contaminants, and then spilled addition to these oil. Note: Oil first filtered before use.
Joe in addition to use of grease lubricated double row tapered roller bearings in the replacement of grease used should be avoided with cotton was then angle to the bearing any part. Because these residual fibers may be wedged in between the rolling elements and damage, especially small FAG Bearings application should pay more attention to this problem.
Check double row tapered roller bearings, do not let the bearings exposed to contaminants or moisture. If the work is interrupted, greaseproof paper plastic or similar material overlying had machine.
