These casters are great; they roll smoothly and more easily. Tires are quiet rolling and compliant but will flat spot a little after sitting in one position. Well made and sturdy.

Having the swivel lock as well as the wheel is an important feature to me. Made a cart for my generator.

These wheels are beasts. Used these to replace a smaller pair. Used them to replace over 32 wheels on 4 professional table tennis tables.

They hardly move with a 200 pound table on them. Just not rigid enough. Garbage, weight rating is definitely not what they claim.
