Match the mechanical precision bearings on request

Precision bearings mounted the steps
1. Match the mechanical precision Precision bearing on request
Since the accuracy of precision bearings itself in less than 1μm, thus requiring its mating parts (shafts, bearing housings, end caps, ring, etc.) have a high dimensional accuracy and shape accuracy, especially with the surface to control the accuracy and Backing bearings the same level, and this is a crucial point, but also the most easily overlooked.
Must also pay attention to match the mechanical precision bearings if it is not the above requirements, often makes precision bearings in the bearing after installation error occurs several times larger than the original, or even 10 times more errors, fully become a precision bearings, because the match machine the error components are often not simply added to the error of the bearing, but on multiple amplified with different additions.
2. With precision bearings
In order to ensure the bearing after installation without excessive deformation, must be done:
(1) shaft and housing bore roundness and the vertical shoulder block bearing according to the appropriate precision requirements.
(2) is necessary to accurately calculate the rotation of the ferrule with the amount of interference, but also suitable for accurate calculation of the amount of the fixed ring.
