Syration Heavy Duty Caster Steel Cast Iron Wheel, Tool Box and Workbench Caster-Set of 4, 4000 LB Capacity (5 inch, 2 Swivel & 2 Rigid)

I bought these for an engine hoist because they are capable of carrying a significant load and they are wide enough diameter to roll smoothly. I was pleasantly surprised by how well built they are and how smoothly they roll. My only gripe is that the swivel casters don't have hardened races for the ball bearings so they will have a short life.

I used these on my car lift for moving around and are very strong

Great wheels. Work excellent for my metal cart.

A good and lasting fix for rubber wheels that only last a few years in Florida heat.

Installed on my 1600lb work shelf, The caster is solid and reliable and very reasonably priced, I am satisfied for this product.

Great wheel and seems strong. However whoever welded the wheel bracket did a real nasty job and material seems cheap.

Bought these to fabricate a set of splitting stands for farm tractors. My tractor is 9000 pounds total and I can easily roll one half of tractor apart with these wheels. Also, they have grease fittings attached. They are very heavy duty. Better than expected!

We have 4 of these steel swivels under our 4’ by 8’ welding table. The table it’s self weighs 980lbs. There is also an additional 400lbs on it currently. You can actually move table with one finger pushing on it! We didn’t expect them to be that great. So we will probably buy a set for the other table soon!
