Should first clean the bearing surface, and then check the bearings carefully check bearing oil seal and the surrounding parts have shown adverse symptoms, be sure to replace the lost, poor seal can cause damage, so bearing cloud not normal and caused the shutdown of the equipment.
Do not check the bearings bearings exposed to contaminants or moisture environment. If the work is interrupted greaseproof paper plastic sheet or similar material to cover once the machine. Case without disassembling may perform inspection, cleaning without masking the bearing to the coating with the brush coated with petroleum solvent cleaning a lint-free cloth to dry or blow dry with compressed air (be careful not to let The bearing assembly is starting rotation). To a small mirror and similar to a dentist with the kind of probe to check the orbital plane of the bearing retainer and beads. Encryption cover is not clean or dust-proof bearings; wipe the external surface can be. If the bearing was damaged that is to be replaced.
Bearing material of choice is a designer based on the functional requirements of the bearing operating conditions and bearing parts. Bearings mainly by the rings, rolling bodies, the holder, and some other parts consisting of its parts and materials can be divided into:
(1) the ferrule and the rolling material;
(2) cage materials;
(3) Other parts such as rivets, dust cover, seals and other materials.
The variety of materials used by the above-mentioned parts due to their physico-chemical and mechanical properties are different, and thus each having different characteristics, in order to adapt to the requirements of working under various different working conditions and environment. Bearing material selection is appropriate or not directly related to the ability to meet the agency's functions and use requirements, has a decisive influence on bearing performance and fatigue life. Usually in the case of the correct material selection, that coupled with the installation, lubrication and maintenance maintenance of normal, the bearings will get a good performance and to meet the reliability requirements.
