Need a smooth-gliding wheel for a DIY project or to fix a sticky sliding door?
This uxcell bearing roller is a handy little piece.

It's a black nylon wheel that's 40mm in diameter and 10mm thick, with a U-shaped groove perfect for guiding along a track.

The groove is about 5.6mm wide and 2.5mm deep.

It has a metal threaded rod (M6 size, 8mm long) sticking out the center, so you can easily screw it into place.
Made of nylon, it rolls quietly and smoothly.

Great for all sorts of things: fixing a wardrobe sliding door, a screen window, a cabinet drawer, or even for homemade projects like a small conveyor or a model.

It's a simple, durable component that helps reduce friction and makes things slide way easier.
Super useful for anyone into home repair or building custom furniture!
