The correct use method can make tapered roller bearings more durable

Although the quality of tapered roller bearings and other aspects are relatively good, but rolling bearings are precision components, and their use must be carried out accordingly. No matter how high-performance bearings are used, if not used properly, the expected high performance will not be obtained. Regarding the use of bearings, there are the following:
 
(1) Keep the tapered roller bearing and its surroundings clean.
Even small dust that is invisible to the eyes can have a bad effect on bearings. Therefore, keep the surrounding clean, so that dust will not invade the bearing.
 
(2) Use with care.
When the tapered roller bearing is given a strong impact during use, it will cause scars and indentations, which will cause the accident. In severe cases, cracks and breaks may occur, so care must be taken.
 
(3) Use appropriate operating tools.
Avoid using existing tools instead, you must use appropriate tools.
 
(4) Pay attention to the corrosion of tapered roller bearings.
When operating bearings, sweat on your hands can cause rust. Pay attention to use clean hands, try to wear gloves.
 
Tapered roller bearings use hearing to identify irregular operation is a very common method, such as using an electronic stethoscope to detect abnormal noise of a part is used by experienced operators. If the bearing is in good operating conditions, it will emit a low whine, and if it emits sharp hissing tapered roller bearings, squeaks, and other irregular sounds, it usually indicates that the bearing is in poor operating conditions.
 
1.Corrosion of tile surface: Spectral analysis found that the concentration of non-ferrous metal elements is abnormal; many sub-micron wear particles of non-ferrous metal components appear in the iron spectrum; the moisture content of the lubricant exceeds the standard and the acid value exceeds the standard.
 
2.Strain on the surface of the journal: there are iron-based cutting abrasive particles or black oxide particles in the iron spectrum, and the tempered color exists on the metal surface.
 
3.Corrosion of journal surface: Spectral analysis found that the concentration of iron is abnormal. There are many submicron particles of iron in the iron spectrum. The moisture content of the lubricant exceeds the standard or the acid value exceeds the standard.
 
4.Surface strain: cutting abrasive particles are found in the iron spectrum, and the abrasive particles are made of non-ferrous metals.
 
5.Fretting wear on the back of the tile: Spectral analysis found that the iron concentration is abnormal. There are many iron components in the iron spectrum, including submicron wear particles, and the moisture and acid value of the lubricating oil are abnormal.
 
Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced, and the oil film also has a certain vibration absorption capacity.
