4Pcs U-Type Black Pulley Wheel 8mm Shaft Hole 30mm Diameter (Max-Load 99kg)

Love them! Right size, price, and smooth ball bearings. I'm going to make a wire straightener tool for DIY and jewelry making. Youtube has lots of demos. No more at the mercy of silly nylon pliers that come undone, and hard on the hands. This will work for miles of wires of all sizes. Thank you!

Came quick and exactly how it was pictured... great product!!!

Not much to say other than they are smooth and well made. They should be able to smoothly roll even with a decent amount of weight.

I bought these pullies to replace some old plastic pullies I had with bad bearings. It was easier and quicker to replace them with new pullies than to press out the old bearings and install new ones.

Pleasantly surprised when these high quality rollers came ahead of ETA. I'm very satisfied with my purchase and would buy again.

I replaced the pulley wheels in two of my 147 year old sash windows with these. The bearings in these modern pulleys improved the design and fit the sash cord diameter perfectly.

For those using inch units, this measured exactly 1.75" OD, with a 5/16" shaft, as per my calipers. Very solid.

The size was perfect and I like them so much I just placed another order for 4 more.

Fantabulous value. No play. Not sure how they would hold up if there were a significant load placed on them, but they seem well made. I wouldn't use them as a spare tire though. Now I just need to find a use for them. I bought them because I like to spin stuff, and circles are my favorite!

Very well constructed pulleys! Was looking for bigger ones as wanted them for a sliding barn door. Too narrow for the steel bar!
