The product is faulty. Center axle diameter needs to match the bearing inner diameter. Currently there is too much play allowing wheel to wobble.
These wheels are big, strong and extremely well made. Brakes hold securely in place. Worked great for a mobile work cart. Harbor freight cart.
They roll smooth, lock down tight and don't budge. They swivel and roll with absolute ease. I have to unlock them by hand, which isn't a big deal, but it would be nice to be able to do it with my foot.
The bolts, lock washers and nuts are sturdy. Definitely heavy duty and came with screws and screwdriver. They are so strong and sturdy.
Whatever bearing they used for the plate feels crunchy. Didn't hold up.
