Still early but seems like there are plenty tough.
Hanging 10’x5’6” steel doors on a pair of these and they are doing just fine so far. The first set has been up for about three months now and nothing seems to be out of spec.

Way smaller than I expected.
I must have missed the description that indicated that these things were less than 1" in diameter. I was sure I sought 2.5" pulleys. Can't use these.
