information on bearings

[MBT]

Yes, something like that
Why do you ask so much information about something like that?
Do you have any serious problems with bulk?

 

[J ax]

No, it's just to know how to draw them :d

 

[MassiVonWeizen]

as I have already told you are not elements that should be drawn. the skf, world leader not the workshop behind the house, does not represent them and not from information about why they do not serve.
you want to do it in the section that you download from the site extend the screw stamp lines up to the hole and add the thread, but just

see the image. the red and green lines I added

I have another doubt about this blessed bearing: Do I have to block the inner ring on one side, for example with a shouldering on one side and an elastic ring on the other, or do I just tighten the pressure screws on one side?

 

[MassiVonWeizen]

bearing with pressure screws? You mean bearings or joint bearings. .
What type of bearing are you using?
how and where is it mounted?
other question... Have you read anything on the skf site on the mounts?
I'll take you back the first line:
"heads y do not allow axial shifts"
The rest you find quiDeduce it's a y-like from the first post you did.
so in the bearings the bearing is already stuck axially, as you should also see from the section. the shoulder can serve for a match of positioning of the tree.
the elastic ring I would say that it does not serve anything except to weaken the tree; if the axial shift is enough to disconnect from the bear the ring if you eat it at breakfast. . .
in case axial efforts are impegantive perhaps you should think of adopting another type of stand. maybe with traction compass
of course from a sentence and a half to understand what is needed is difficult
put a sketch of your solution

I have practically a tree that I have to bind with two bearings like the one attached in the first post that is equipped with support (but is it said support or stand?). I then put the shaft in the 2 bearings and screwed the two supports to the side plates then the outer rings of both bearings are stuck axially and then I thought on a bearing to tighten the pressure screws to support the bearing axially, while on the other bearing I do not screw pressure to allow axial shifts of the shaft due for example to thermal expansions. Can this go?

Bye-bye
with the y bearings mounted on the relative supports (or bears, I think they are correct both but the last is more...arcaic!) y you can not have axial movements. basically your tree becomes hyperstatic, with the consequences of the case: You must be pretty sure you don't have thermal expansions. In any case, I would limit the distance between the supports precisely for this reason.
are suitable for very economical applications and always require the fixing of the inner ring to the shaft or with the pressure screw or with the traction compass.
Are you sure this solution is consistent with your apllication?

If I at the 2 sides of a tree put 2 bearings of this type, with already flanged support, the pressure screws I have to tighten them only on a bearing or on both?

I would say that I have to hold them only on one because if I tighten them on both the tree becomes hyperstatic while it is always necessary to ensure an axial shift so that if there are thermal expansions the tree can indulge them without being stressed.
Is that right?

If you want to make an isostatic axis, it must be stuck with grain only on one side
