How to set bearings

Simulation Generality
1

Hi all 

I'm working on a project for a TV stand, my problem is that I have a final extension of 1.5m with a maximum weight of TV (about 40kg)

I designed the support but my concern is to select the right bearings for each axis of rotation "ball, roller, needle, etc... ".

I was told that there are plastic washers that allow you to slow down the rotation slightly but I can't find them, if you know the name?

Do you have any suggestions?

See support in PJ

Thank you

The choice of your bearing will depend on your load. Then, you have to make the right proportion between the costs borne / the price of the bearing and the conditions of use

 

Edit: And if not, for your wall mount, I might go more towards a bearing  than a ball bearing

Hello

Ball bearings for TV stands!

A system with rings should be more than enough.

Hello

For rotational damping I use ACE products:

Hello

On this link:

I have the impression that the rotation is done via an axis in tubes (material-material contact on the rotation) and that these elements are separated by plastic rings to limit friction

Hello

Indeed, putting bearings for a TV stand is a great luxury. Plain plastic bearings are more than sufficient given the frequency and speed of travel.

Now, if you really want to use bearings, there is a lot of information directly on manufacturers' websites. example at INA FAG

Hello

to have one at home, I can tell you what a CHC screw is that passes through a spacer.

Much less expensive than a bearing or a bearing.

Happy studying!

Thank you very much for your answers.

For the moment it's chosen roller bearings but I wonder if ball bearings wouldn't be enough.

For information:

The arms are drilled at the axles, there is a tube in them welded and I put the bearings in the tube and then the axle.

I was given a hard plastic washer that could be used as a brake since I have the axles screwed in
