Fangding bearing proper use

Proper use of spindles bearing:
First, in the bearing housing bearing fitting hole size, shape, and precision is not good, the bearings will be affected, you can not play the best performance. For example, if the inner part with the bearing hole dimensional accuracy and shape accuracy is not good cause bearing outer ring deformation, resulting in deterioration of bearing roundness; if precision is not good stop shoulder, will have bearing outer ring, roller tilt, intensified focus load bearing fatigue life drops, more serious cause holder breakage, sintering; if the precision spindle bearing inner ring gear rod bearing bad, such as size, roundness, cylindrical, waviness, roughness, location of accuracy, etc., will also contribute significantly to increase the value of the entire spindle vibration.

Secondly, assembled bearing prior to assembly rigorous precision matching, so the user before use, scattered bearing parts without re-measuring matching, are not interchangeable.
Thirdly, spindles and spindle bearing foot cleaning problems. Due to the compact structure bolster, bolster cavity there are many other components, their cleanliness also affect the cleanliness of the bearing cavity. Therefore, before using the bolster assembly parts prewash, after assembly assembly, and then to bolster assembly includes a bearing fine-cleaning process is a more reasonable process method.
Fourth, the bearing in the assembly should not be subjected to bump and shock, bump and shock could easily lead to a collision between the bearing parts, resulting in bearing failure.
Fifth, when the chock crimping bead pay attention to control the angle, intensity and other factors, to avoid crimping unreasonable failure caused by deformation of the bearing parts.
Sixth, more than rust or store longer bearing, the situation may be due to rust or rust oil dry and sticky rollers appear dead.
