5 Inch Caster Wheels 2400lbs,4 P... vs 24 Pack 2" Caster Wheels Swivel ...

The swivel lock is a plus as it locks the position of the caster as well as the rotation of the wheel. Roll and lock great. Smooth ride with easy locking and unlocking.

Inch wheels have more enclosed bearings at the pivot plates. Larger wheels also help going over larger bumps and cracks on driveways. No issues with getting stuck on pits in the driveway or little stones.

Also, whatever bearing they used for the plate feels crunchy.

These wheels are on shop tool storage cabinets. They run smoothly and lock easily. Roll smoothly on flat wood floors.
