Although you can install the "freedom" of all types of bearing seal, but there are still 36% of the early failure of the oil-free bearings incorrect grease and improper use. Any improper lubrication of bearing failure in the normal life forward. Mac hinery and equipment bearing is usually the most difficult part of the work, there is no fixed lubrication is a problem. Maintenance manual, and it is impossible to achieve, automatic lubrication system, can be developed in order to achieve the best lubrication effect. Grease, tools, and effective lubrication technology, will help to significantly reduce downtime.single ball bearing
The non-oil bearing parts subject to unusually high temperatures in use, and lack of timely cooling parts of the surface tissue will generate high-temperature tempering or secondary quenching phenomenon called burns.
Burns generated mainly due to poor lubrication, load is too large, the neck and the inappropriate choice of clearance, improperly configured bearing raceway surface poor contact due to excessive stress due to the cold. Such as;
1) in the axial moving bearings, if exogenous fit tight, can not be moved in the housing bore;
2) bearing the work operation temperature, the thermal expansion of the shaft caused by a large axial force, while the bearing can not move axially;
3) due to inadequate lubrication or irrational lubricant selection, quality problems, aging and deterioration;
4) operating temperature difference inside and outside, plus clearance inappropriate choice of both external expansion small internal large was interference led to a sharp increase in bearing temperature;
5) The oil-free bearings to withstand the load is too large and cut in uneven load distribution, the formation of stress concentration;
6) Parts rough surface processing, resulting in poor contact or film formation difficult.
