I mounted them on a stand for my drill and belt sander. They hold the weight well and are very stable. When unlocked, they move easily and spin freely. My only criticism of these wheels is that they don't have enough rubber surface that the table they're attached to moves easily even when they're locked. They stood across the floor, locked too easily. I wish there were more high friction surfaces around the perimeter. As I don't put too much lateral force on the kickstand it's not really a problem, but if it's something to bump into or have horizontal force applied to, they'll likely move around a bit even when locked.
