High speed angular contact ball bearing(71800C/71800AC)

Back to back configuration, the rear code for DB

What is the back configuration simply refers to the bearing outer ring width face wide, or a small end face of bearing inner ring installation small end. This is a kind of installation that we should use frequently, compared with the other 2 ways, it has the following advantages:

(1) the load it bears is separated from the bearing axis, and the attention is separated.

It can bear the axial load on 2 directions, but the load in each direction can only be borne by one bearing.

(3) can adapt to the relatively high rigidity of the bearing configuration, and can also withstand the overturning moment.

The combination of these 3 advantages, it is not difficult to find, back configuration installation is the load bearing axis to separate, there are advantages to separate the load bearing and shaft, and it can withstand overturning moment, if coupled with the choice of suitable contact angle, you can imagine, in the actual operation, can save how much maintenance labor can avoid many possible accidents? Therefore, the actual situation on the basis of experience I recommend first back-to-back configuration.
