oblique bearings recording

[AndretheGiant]

Hello, everyone!
I have no experience using oblique bearings. I saw that recirculation screw supports should be used. Meanwhile I wanted to understand why they should be used even if I have no axial load.
Then I do not understand this suggested disposition dda skf. having the bearings attached if I tighten the ring the inner ring does not move from how I understand.. shouldn't there be some air between the inner rings to allow the recording?

before you say you don't understand why you don't look at how oblique bearings work and everything will be clear to you.

then let's say that I am clear this assembly because there is air between the two thicknesses, so by screwing the wreath you can adjust the game, but on the image I attached before there is no light, for that I do not understand how you can record

You don't have to record it, lock it up and it works. is already regulated in the factory.

p.s. I referred to the first bearing indicated.

In reality it is a flange that must hold the drive generated by the endless screw for which the axial load of the application exists and, probably, also relevant.

the image you have shown shows an example of bearing arrangement blocked support in which the application of the preload by the user is not foreseen as there may be three conditions (see pdf attached with extract from the schlaeffer manual) regarding the bearings already prepared by the manufacturer with:
- light axial game;
- without play;
- light preload.

the internal space is instead foreseen in the type of assembly to recorded support where the application of the preload is entrusted to the wreath and design specifications as well as to the sensitivity of the operator.

screws recirculation or any screw has only axial push, so you have to win this force. there are the bearing units specific zklf or similar that do not need registration.
If you have a particular and different application you need to evaluate the thing. If you don't axially prevariate you'll have the bearings dangle.
If you are looking for on the skf site you will find explanations.... on how and how to change.

Now it's all much clearer, thank you. I didn't think the screw pushed axial. therefore it would be good also a single oblique bearing with two crowns of spheres instead of the two coupled

Whereas (skf) i oblique bearings to a crown of balls for universal mounting and attached bearing groups can be
combined in different provisions, which vary according to the degree of rigidity and the requirements for the load imposed by the application.
I'm sorry. two crown oblique ball bearings occupy less axial space, so they can be used in applications where oblique ones to a crown of spheres available "or" occupy too much space.
They also have a rigid bearing arrangement and can withstand both tipping and radial and axial loads acting in both directions.
