Reasons for difficult rotation of bearing axis
As an important part of mechanical equipment, when we find that the bearing is in operation, the axis of the bearing always feels unable to rotate, that is, the so-called bearing axis is difficult to operate? What’s going on? According to the actual situation, it can be seen that many people will ask such similar questions, and China bearing network will give you relevant answers.
Why is it very difficult for the bearing shaft to rotate? In general, the main reasons are as follows. We can consider these aspects and find corresponding methods to solve them.
1. Lubrication failure, high or low oil level, improper selection of bearing clearance.
2. The cleanliness is not in place, there may be sundries.
3. The positions of oil seal, shaft shoulder and seal, anti loose plate (sun plate) are inappropriate.
4. The concentricity of the shaft is not correct, and the axial jamming is caused by cross positioning.
5. Low precision and distortion of bearing housing
