uxcell U Groove Guide Pulley Rail Ball Bearings 6x21x7mm Double Metal Shielded (GCr15) Chrome Steel Bearings Roller Guide Wheel 2pcs

Good product

Smooth and utterly quiet. Great produce and fast shipping.

I had a 1 inch screen door wheel cartridge that I could not find a replacement for anywhere. So, I had to drill out the rivet and replace the wheels By hand. Be careful with measurements, especially the bearing width, but, it was pretty easy to do. I got some screws that had the nut built into the shank, like you see in furniture sometimes. Worked like a champ and my screen door rolls like butter now! The ball bearings in these little wheels are great.

Muy complacido. Comonoo esperaba

works great

I used them to replace the rollers in the doors of my harbor freight greenhouse. They are the same center diameter but a little larger so it rolls smother. I had to pop the brass hubs out of the original roller s and pop them them into the new roller.

No good quality

I bought these to replace bad bearing rollers on my bathroom sink, the front has sliding doors. They work perfectly! The original ones were black but the white goes very well with it and the doors slide better now than when they were new!
