Bearing use and fit
Rolling bearings make precision parts, and thus require a correspondingly cautious attitude in the use of both the use of high-performance bearings, if used improperly, can not achieve the expected performance results, so the use of bearings make the following matters should be noted:
Bearing storage should pay attention to the problem
As long as the relative humidity in the storage room does not exceed 60% and the temperature does not change much, the bearings can be stored in the original packaging for several years. Sealed bearings or bearings with dust cover, after long-term storage, the lubrication characteristics of the grease filled in the bearing may be reduced.
Inspection and troubleshooting of bearings in operation
The inspection items in operation are rolling sound, vibration, temperature, lubrication status of the bearings, etc. The details are as follows.
How to choose the type of bearing
About how to choose the brand and type of bearing has been introduced, but the bearing some about the more remote, or often ignored, do not pay attention to the common sense many times on the use of bearings is to play a very important role, the following I come to popularize for everyone.
The Use of Bearings
Bearings are precision components, their use must also be appropriate caution. Regardless of how high-performance bearings, if used improperly, it will not get the expected performance. Note the use of the bearing is as follows:
Bearing Basics
Generally within the inner bearings, outer ring, rolling elements and cage composed of four parts. For sealed bearings, including lubricants and seals of two parts. Bearing in work, able to withstand the radial load or axial load, at a certain speed of rotation, will produce radial or axial runout.
Bearing Removal
Bearing the demolition, is regular maintenance, replacement bearings were. After demolition, such as the use or need to continue to check the bearings of the state, the removal and installation should be as carefully.
Bearing Life
The performance of rolling bearings, for different purposes, shall be required to maintain its performance during the period. Even if the correct bearing for a particular purpose will, over time, noise, vibration, increased wear and tear caused by decreased accuracy, grease aging strip rolling surface fatigue can not be used.
