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

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

Q: Will these work with 5/16 cable?

The width of wheel is 3/8 with 1/16 wide peak on each side of half round concave U curve for the 1/4 inch cable to ride freely on, 5/16 cable looks like it would still work, will be a tight squeeze and would be the maximum size cable this roller is made for.

Q: Are the ball bearings stainless steel?

They have lasted me years in the weather. Everything you can see on them is stainless. As for the bearings inside, I don’t know, never had one go bad and my oldest ones are at least 3 years old and exposed to all the weather. They are hardiest I have ever used.

Really nice and solid

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.

Wrong size for Coverstar Automatic Pool Cover

Recommended by Amazon, but wrong size for Coverstar Automatic Pool Cover. These are 1.24" and you need 1.14" for pool cover. These will not fit and will be a waste of your time as it was mine.

Good Bearing, not sized as listed

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 aren't 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 doesn't matter (no joke intended), but not sure why you would put dimensions in a listing if they aren't right.
