The ball casters are great swivelers and quite snazzy looking, too. Seen on your better chairs everywhere. These are brass plated on 1-1/2" square mounting plates with 3/16" holes at the corners. You pick the 2" or 2-1/2" dia versions.
Good-bye backaches. Save your sacroiliac with a 3-wheeled professional mover's dolly. It measures 6-3/8" wide between a trio of swivel casters with 1-9/16" x 11/16" wheels, and has a drop-down center and a 1/2" dia hole for permanent attachment to frequently moved items. Steel construction, 110 lb max load (so not piano-duty), and rubber pads above each wheel. Stands 2-1/2" tall. We think ordering (4) would be a good place to start.
Our 4" dia swivel-stem casters have 3/4" wide dual black-plastic wheels and 1" steel stems with 1/2" - 13 threads. Available with or without a foot-operated lock No weight limit listed, but they're pretty sturdy, and pretty snazzy, at least to the extent that casters admit of snazziness.
You don't have to be a creep to need creeper casters. These are a lovely tomato-soup-red hard plastic and would serve a number of things besides creepers. Measure 2-1/2" dia x 13/16" thick, and swivel on a threaded 1-1/2" stem and threaded female bushing (without the usual 45° tilt). Come with (2) washers.
This set of (4) stylish gray plastic casters includes (2) fixed and (2) swivelers. All have double 1-1/2" dia x 1/4" wheels set on an axle and are 1-3/16" wide overall.

Move it with our light-duty swivel-plate casters. They have dual 2" dia x 3/4" wide plastic wheels on a 3-3/4" x 2-3/4" plate with keyed 5/16" mounting holes at each corner. They spin on 3/16" dia axles, and have a brake.
This extremely sturdy stem caster has a 4” dia x 1-1/4” thick gray rubber wheel on a 5/16” axle. Has a ball-bearing swivel stem mounted on a 2” dia plate, locking foot-lever, and a 1” long x 1/2”-12 thread. We’re thinking major-league millwright’s toolbox or something equally heavy.
That is the question. You pick: the 3” x 1-1/4” dia swivel-stem caster with a rubber-coated plastic wheel on a 1” long threaded stem, or the same thing with a lever lock on the bolt side of the axle. Both have 1/2”-12 thread.
