Review on Shepherd Hardware 9807 Diameter Capacity by Eric Ross

They were used in my husband's office chair. He's a big guy, almost 300 pounds. Five of them, totaling 875 pounds, were supposed to carry his weight but failed. Now, without bearings, the wheels don't spin easily on the stem, and the chair is difficult to move, especially under weight. No guarantee? There is also a carrying capacity discrepancy between the title and the description. The title says 175 pounds but the description says 110 and lists a different model. In any case, he still had to carry the weight, but he didn't.
