It is fine.
I use mine to attach TPU, which is a soft material and even that doesn’t stress it out. It doesn’t cause any issues in the print, doesn’t snag, all is good.
TPU would snap if there is an issue.
Trust me, you have what you need.
You may have seen the AMS lite, it has cylinders which lock into place inside the hole within most spools. That is used as it has motors to push and pull the filament as required during multiple swaps. When you are using an external spool, the only action is drag.
Some add a different type of spindle with metal bearings. I have been 3D printing for many years and have never used or required one.
On an old 3D printer that had a rougher surface spindle, I placed a toilet roll tube over the spindle. The cardboard acted as a simple ‘slip’ device, old school for old times.
