5" X 2" Heavy Duty Industrial Casters,Polyurethane Tread Cast Iron Wheel (Non-Marking) Caster- 4000 Lbs Capacity Per Set of 4 (4 Brake)

I used these casters on a shop cart. The cart itself weighs over 100 lbs. I can load it up and stand on it and these casters can take any load that I can pile on. I know that these are more for industrial applications, but for heavy loads around the home shop these are awesome.They roll smoothly round the shop. The ball bearings make turning the cart around really smooth and easy.

These are very well made casters. I like the cast iron wheel with the polyurethane tread. The cast iron center means it won't distort when it sits in place for a year or two on a hard concrete floor. And the polyurethane tread means it won't destroy the painted concrete floor.The only downside is, if you're rolling a heavy item on a concrete floor, these are a bit louder than a plastic hub wheel. But if your load is heavy enough to notice that, I expect you'd be at or over the load rating of a plastic hub caster - which isn't good for long term reliability. I guess that's a long way of saying, if you notice a downside these, that means you need these :)I like the redundant grease zerks on the wheel & axle. Either will get the job done. But sometimes reaching under a heavy item and getting to a grease zerk may not be easy. So they give you two options. If you look closely, you'll notice the axle zerk is on one side, and the hub zerk is on the other. So whichever side you have access to, there's a zerk.

Seems to be a pretty good caster and the weigh capacity is what I needed. The ball bearings for the caster seem to be a little to exposed for my liking but time will be the judge. (I just put them on last week) The price sure beat the factory replacement price of $160 per wheel.

These are extremely solid and well-made caster wheels. I have a bunch of different woodworking tools, like table saws, etc, and use these to build rolling carts and tables for the tools. These have no problem holding the wood and tool up, and they are simple to roll. I would recommend these for anyone needing solid caster wheels for any project.

These were 4'x2' carts and for whatever reason, they do not spin freely. Rolls in a straight line fine, but only once you get them turned in a straight line. They just do not like turning. Acts like the bearings are not smooth/properly rounded. Not just one defective wheel. Seems like it's an issue with all of them.We greased them thinking that has to be the issue, and it wasn't.Very disappointed in this product and definitely do not recommend them. I'd return them if I could.

These casters are extremely heavy duty. I was a bit misled by the images as they showed the casters attached to push carts and such which were the application that I was looking for. However, these bad boys are made for more than push carts or garage/woodworking workbenches.They are pretty heavy and solidly built. They have grease gun attachment points to grease the bearings in the pivot and the axle of the wheels which lets you know how heavy duty they are. They would be great for full sized heavy tool boxes or for carts moving heavy metal objects such as a mechanics shop.They don’t come with any hardware such as bolts or screws so you’ll need to provide those yourself. They also have no breaks so keep that in mind.The casters are pretty nice and a bit much for what I was looking for but that’s due to my inexperience with heavy duty casters and my reliance on the images the seller provided.If you are looking for heavy duty casters that roll super smooth and allow for easy greasing, I would definitely recommend these casters.

Picked these up for a rolling cart project of mine and they are so much sturdier than I had anticipated. They could easily handle three times the weight capacity of my project, that just means they will last longer for me. I am very happy with the casters. They move easily and have no defects in quality.

Note: I see that the product description and photos have changed since I ordered these. This review is for 3” casters with black wheels and no brakes (see photos).I needed a set of casters to turn a small stand into a rolling cart and these looked more than adequate. As soon as I picked up the box upon arrival, I could tell just by the weight that these were far heavier than I actually needed — though they worked just fine for my purposes. Construction is super heavy duty with very thick stamped sheet metal bases, heavy axle, and a much heavier wheel than I expected. The ball bearing swivel mechanism is smooth, though a little stiff only because of the weight of these casters and the load they are intended to bear. What the product photos did not show well was the hefty width of the wheel, a bit under 1-1/2” wide and very thick plastic. These are supposed to be rated for 800 pounds, and I believe it! For smaller projects (like mine) look for a sturdy pair of 2” casters, but for a heavy-duty rolling project, look no further than these!
