5PCS U-Groove Pulley Roller Wheels with Deep Groove Ball Bearings, 8x30x10mm Silent Nylon Guide Track Rollers for Sliding Doors, Windows, and Gym Cable Systems, Heavy Duty & Smooth Motion

We used these to build a Roman Curtain style rig for raising/lowering a projection screen in a recent Community Theatre production. I used them to replace the noisy metal wheel that was in the pulleys we purchased at Home Depot. They were priced perfectly and worked great!

Used this to fix pulleys on a sail boat mast, they worked great! Quality seems good...

The part are great but I ordered the wrong size

works well

happy with everything

The bearings are press fitted and came loose several times during mounting. Also, the outside of the bearing are not flush with the edges of the pulley, and make traditional mounting difficult. The bearings are inset.

Good quality - smooth spin. Used for my nephew's Rube Goldberg Tracks.

Worked well for my project

Excellent product. We wanted something small and smooth rolling for use in a DIY sliding barn door. These bearings are perfect. The door is hung and in use on our closet. Working great, easy quiet super smooth action . We used some vintage cabinet pull as a doorstop as it slides so easily.

Très bon produit. Correspond à la description

excellent quality

Liked these better than the Atoplee ones, I use them as replacements for the ones on my rowing machine. The quality seems much better so far.

Je les aimaient elle était solides mais elles sont trop grosses pour ce mécaniste c’est n’est pas grave j’en ai commandé d’autres plus petites
