The power running starts from the no-load low speed and slowly increases to the rated operation of the specified conditions. During the test run, the items are abnormal, the temperature of the angular contact ball bearing, the leakage or discoloration of the lubricant, and so on. If an abnormality is found, stop the operation immediately, check the machine, and remove the bearing check if necessary.
1. Keep the bearing lubricated clean
Before inspecting the INA bearing, the surface of the bearing should be cleaned first, and then the oil seal of the bearing and its surrounding parts should be carefully inspected. If there are any bad symptoms, be sure to replace it. The bad oil seal will cause damage and make the angular contact ball. The bearing cloud is not normal and the equipment is shut down.
2. Pay attention to cover exposed bearings
Do not expose the bearings to contaminants or moisture when inspecting the INA bearings. If the work is interrupted, the machine should be covered with a piece of oil-paper plastic or similar material. If the unshielded bearing is cleaned without performing disassembly and may be inspected, use a brush for application to clean with a petroleum solvent, then dry it with a lint-free cloth or blow it with compressed air (be careful not to let The bearing assembly starts to rotate). Check the track faces, retainers and beads of the bearing with a small mirror and a probe similar to that used by dentists. Do not clean the bearing with a sealing cover or dustproof; just wipe the outer surface. If the bearing is damaged, it needs to be replaced. The replacement of angular contact ball bearings during regular downtime maintenance is far more economical than the loss of sudden downtime selected due to damage to the array.
3. Check the lubricant of the bearing
Lubricants are important not only for bearings but also for all bearings. However, please note that it is not advisable to add too much grease to the bearings. Then it is to replace the lubricant of the INA bearing. An oil-lubricated angular contact ball bearing 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 residual contaminants and then vent the oil. Bearings lubricated with grease should be replaced with any contact with the cotton material when the grease is replaced. Since these residual fibers may be wedged between the rolling elements and cause damage, in particular the application of the bearing needs to pay attention to this problem.
The life of INA bearings is closely related to the manufacture, assembly and use. It must be done at every stage in order to keep the non-standard bearings in optimal operation, thus extending the service life of angular contact ball bearings.
