4 Pack 3" Heavy Duty Caster Wheels Polyurethane PU Swivel Casters with 360 Degree Threaded Stem 800lb Total Capacity for 4 Pcs Red (4 with Brakes) Nuts Include SM-AMS-230008

My table saw weighs about 250 lbs., so it's been very hard to move. Now I can move it anywhere with one hand and when the wheels are locked, it stays put solidly. The wheels are well made and will last longer than I will. Like all bearings, of course they need a little grease.

I am totally impressed by these locking casters on threaded posts. Both the wheel rotation and pivot motion are locked by the foot lever. The wheels appear solid, sturdy, and well built. The locking levers are easy to engage, and stay put. When rolling, the action is smooth and effortless, even with a heavy drum sander (200lbs.) Since the wheels are 3" diameter, they wont go over power cords very well, but I usually don't expect that from smaller casters. You really need 4" casters to go over extension cords. But, bigger casters would have raised the tool too high. I am very satisfied with these locking casters, and would certainly buy again. Great product!

Wheels seem sturdy, movement seems fairly fluid. 3 out 4 work flawless, that fourth one though, it will not swivel, it rolls about just fine but no swivel action. I'm hoping to hear back from the manufacturer to see if we can't get this sorted out.

Very durable wheels. I used these to make my 20 ton press movable and they work great. I drilled the holes in the presses angle steel legs and fastened them with the provided hardware. They are solidly built and move the press around effortlessly. The press itself only weighs a couple hundred pounds so these are well within the weight specifications of the wheels. The locking lever holds the wheel very securely. Great upgrade to the press.

I used these casters for a mobile machine stand I fabricated for a 400 pound band saw. These are more than up to the task. They swivel very easily, and my machine can be moved around with one hand. The locks are very solid; with all four wheels locked, it's as solid as when the machine was on the floor.

Like the sturdy feel and heft of these casters. I installed them on a 300lb. belt sander and they fit like a glove. Although the ad didn't say, there are 4 lock nuts and washers included, and they make installation easy. They gave the impression that they might just support the claimed 800 lbs. the ad states. Red polyethylene tires should last a long time. I like them, and they were 72 dollars cheaper than the ones from the manufacturer.

Just put on. One already won't swivel.They have a nut on the top to tighten, but design is poor wrench won't fit in to tighten it so much more difficult than it should be to install.Wish I hadn't waited so long to use them. If I hadn't they would be going back. Instead they will just go in the trash.

I put them on my welding table. It's up about 3" higher than it was with the included feet, and it rolls around so easily now. The locking feature is great too, and just as necessary for welding. The only issue I foresee is that the caster swivel rotation also locks, so if counter-clockwise torque is applied to the caster while it's locked, it may unscrew from the table leg. They need to be tightened properly and thread lock will help too (I didn't use it).Also, the nylon rings in the lock nuts are pretty low quality. They leave blue plastic all over the threads of the caster studs as you screw them onto the studs.
