Stainless Steel 5mm Deep U Groove Ball Bearings Pack of 2, Pulley Bearing Wheel Rail Ball Bearings Wheel

These are the best I can find. I wish they were cheaper but quality sometimes costs.

Good high quality bearings. Works great in my pully system I have set up in my garage.

Todo fue perfecto.graciad.

Our zip line OEM bearings were so cheap that they were worn out after less than three months of very light use. These units made our line faster and smoother than new. Haven’t had them long enough to report on longevity.

Its not actually a deep V. Its more comparable to a u groove.

Very heavy duty which is good using it to make some barn door window coverings

These are awesome bearing pillows. Thank you.

Its working

There nice.Super smooth and heavy duty.Used them for an anchor system on a drift boat that I’m building

I used these pulleys for the 1/4 rope on my automatic swimming pool cover. I was not sure it was going to work when I received them because the U groove is shallow (Not deep as advertised) however, it seems to function well. I am satisfied with the product.
