Porter Cable 903373 Belt - Random Orbit

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.

This is a great repair part for your Porter Cable palm sander.

This product arrived quickly and fit my Porter Cable 333 random orbital sander perfectly.

Great fit but do not try to roll on to the spindles. Instead, stretch straight out over the spindles. I found it was the only way to get the belt on without popping off when putting this disk back in place.

Easy to get the right part and arrived quickly.

Brought back new life to my old trusty 333 sander. Easy install.

Works as expected, but a little pricey.

Quick delivery and fits my sander

took awhile of watching this product for it to be available. Finally received it, and works great

Just what I needed to get my sander working.
