I have the Woodcraft casters like the ones (all bought from Woodcraft over the years and always on sale) you just installed on everything/tool in my shop except the PowerPro and it has the upgraded caster set from SS. I have used these casters (some for well over 25 years) and have never had one fail so I think you will be happy with them. I have a set of 6 on my mobile plywood/scrap rack which probably tops 600# and they work like a champ. The ones with the heaviest load to get a small flat spot on them if they set for an extended period but still easy to start rolling and round back out near instantly.

First the problem was not weight. The orange/red coating peeled off. It was like peeling a tough orange. The composition of the product was changed, it crumbled and it simply peeled away. In fairly big pieces. I peeled all four wheels now I have 4 2 1/2 inch casters. I put the new ones on the bench we will see how long they last. I have a set of similar although not the same casters from Shopsmith for mounting on my Shopsmith but after this I am in no rush. The old casters on my Shopsmith lasted 35 years those on my work bench less than 10
