The swivel and wheel both have ball bearings. The locks work great to prevent this from rolling down the slope of the driveway.

Appears to be a quality product that is very usable. Highly recommend purchasing this product.

Made a cart for my generator. These appear to be strong and sturdy. Well built and feel sturdy.

They fit on my qsc ks118 powered subwoofer. These are great casters, especially for the price. These however are fantastic!

They hardly move with a 200 pound table on them. Had flat spots after mounting to a table weighing less than 100 lbs. Not at all happy with them.

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.
