Porter Cable 903373 Belt - Random Orbit

Exact replacement works great

It fit my old Porter Cable 333VS palm sander.

The belt has met my expectations as I have used the sander after installing the belt. My sander works like new. Thank you for a very good product.

Replaced this because I replaced the pad

Quick delivery and fits my sander

I was ready to throw my old sander away until I found this part on Amazon (where else). Very easy to install with nothing more than a screw driver. Remove 3 screws, remove cover, install new belt.

The product was received in new condition and unlike original belt, this one came in clear and appears to be of good quality so thats why the 4 stars. I have installed the belt and run the sander but have not put it to sanding duty yet for testing, so I may update later when I do if I believe the rating needs a change. Its a belt so as long as the sander operates properly and the belt is not an issue (the original lasted years) Im good with this product.

Let me add my 5 star review to others. Worked a treat. Of course the old belt broke on the first piece of my project but a square sander did the trick. Not as well but it worked. Well pleased to get my go-to sander back.

5 stars is for ease of installation and proper fit. Cant report on longevity.

This is a very stiff belt. Instead of transfering about half or so of the motor spin into random orbit action, it just sort of locks up and the sander spins up like a non-random orbit sander. If you turn it on and wait more than a couple seconds before appl7ing it to the board, it sands fast, but not smoothly. Not good.
