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

Nice product. Machined and surface finished nicely. Rolls smoothly around the axis. No crunchies as they say. I actually bought more for my project they were so nice. Hopefully this is a good supply going forwards.

The bearing I just received (S608z) seems to be of nice quality (maybe a 4 or a 5). Seems tight and good finish. But the dimensions listed arent close to actual. The bearings I just received had an outside diameter of 31.5mm, and a width on outside of shoulders of 12mm (10.43mm for width of rotating pulley). The shaft appears to be closer to .25 (6.4mm). And depth of groove is 2.8mm. Maybe size doesnt matter (no joke intended), but not sure why you would put dimensions in a listing if they arent right.

Not 7mm as described. When another reviewer said it fits a 1/4 inch bolt well, that is because it IS a 1/4 hole.

Dislike fact soap was not included

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

Great product, rolls well, no wobble, precision made, would buy again for this and other projects. Highly recommend. Also really nice a 1/4 inch stainless steel bolt fit just right.

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.

The bearings seem to be of good quality and should work well for our intended purposes.

Its working

Todo fue perfecto.graciad.
