CNBTR4PCS U Type Groove Plastic Guide Bearing Pulley Wheel 34mm Outer Diameter 8mm Shaft Hole for Max-Load 79kg, Sliding Door Window Roller, Office Equipment Roller

The pulleys have good bearings and are well made. They are dimensionally accurate.

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 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.

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

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

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

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

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.

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!
