Roller end caps from pvc or nylon Help!

[m_c]

Looks fairly easy to do, however an idea of tolerances are needed.

Is the part to be a pressfit into the roller, or a slight clearance fit to allow it to be glued/bonded in?
Is the recess in the rollers consistent?
i.e. are they a consistent size, and true.
If they're not, then it may be better to machine the shoulder, press/bond them in, then machine the through hole/bearing recess/belt groove to ensure things run true.
I'm guessing the bearing will be a pressfit?

Also, how many?

It's not a hard part to make, however there's lot of potential for things to not be quite right without the above information.

Hi. Thanks for the reply. The caps coud do with being a nice tight fit, as not planning on using glue. There will be a axel through the roller with a nut each end compressing the caps. This should be fine and I can send you a section of the roller. All the roller sections are of the same diameter.

The bearing does need to be a press fit. Not sure how much smaller the cut out would need to be but I can send you a bearing.

I only need 2 with the groove and 4 without the groove for the first one. I can supply the Nylon or Pvc rod.

I got some dimentions wrong again! So here is another drawing.


Cheers
