Yup. I'll have to wait until I build my step box and then figure out
how much it weighs.

According to the description, spring loaded casters are designed to
minimize shock so to protect the contents in the box.
What I'm looking for casters for a box that wil ground itself when
some weight is put on it. Without that added weight, the box will roll
freely when pushed.

Thanks, not what I'm looking for. What I want is casters that will
hold something up so it can be pushed easily. Then when a little
weight is put on it, it will ground itself on the floor.

Just search for spring loaded casters.
I just did and there are plenty of different types that do what you want.

There are industrial step platforms that work exactly like that. The
casters have springs and the step bottoms out as soon as you put your
foot on it.
Ladder casters, side mounted, will do what you want. They can be
mounted inside to be out of sight. Under compression, the steps contact
the groun and the caster does not roll.

The problem as I see it is that OP wants a caster that will support a
50# box and yet settle to the floor and remain stationary when he places
slight amount of weight on it.
This "self stabilizing" is what going to cause him grief in his quest.
What's a manufacturer to do? Offer a whole range of casters by weight?
A number of them with an adjustable range? What's the demand likely to
be vs one that can be lowered and locked manually like those used on
woodworking machines as previously mentioned.
Far better, I think, would be for OP to design his own rig. What
immediately comes to mind is a set of casters, appropriate to the task,
mounted outboard on slightly extended arms with a fulcrum close to the
edge. The "Inner" arm would extend toward the center of the box and an
adjustable spring/turnbuckle arrangement would adjust the casters to the
weight of the box to the point where you could balance it and have it
settle to the floor with the addition of a little weight.
It would undoubtedly be clearer if I could post a drawing but you get
the idea

One more thing.
These are awesome little step ladders. I remember them well.
I am sure they are pricey, but they might already have the hand hold
that you need to shimmy up.

The ladder casters I came across in my cursory search were available in
various weightings... some with 25 lb springs. If this is too strong of a
spring perhaps the spring loaded casters as used on walkers would work...
check a DME vendor for replacement casters.

I think what you're looking for is called a "spring loaded caster".

well then you are not paying enough attention. if you get the right
spring it will.
There are spring loaded for gates, spring for shock.. And spring for
what you are looking for. Look for the weight you want.
Each has a resting weight.

Well, one could easily adapt an auto 'air spring' adjustable suspension
strut to lower a couple of wheels. Or, just mount a suitable auto
helper spring/shock assembly with the right leverage on a pivoting
pair of wheels (next to fixed legs). It'll look like it came from a truck
undercarriage, of course. Strong design element!

But there ARE some good searches on ebay that are in the range..
40lbs.

Look about 20 or so items down, there are 40lb rated springs, which
means you would need to be 160lbs.

Thanks. I'll be building a carpeted, plywood stair to conform to the
size of my butt. I'll also be installing side handles to assist
lifting myself up the steps. When I get it built I'll put a .jpg of it
in ABPW.

There is one made exactly for my purpose. It's called a Para Ladder.
http://www.paraladder.com/
I emailed the company, but didn't get a response. In any event, it
would be cheaper for me to build one suited to me. That means thick
shag rug on the steps, width to my specifications and deeper steps.
I figure it can do double duty as ladder onto my bed when my cat gets
too old to jump on the bed.
And, I'll be using this project as an excuse to by myself a Festool
Carvex jigsaw. Leon needs his commission. :)
The only type casters that I know about to accomplish what you want are
made for woodworking machines or work bench mobile bases.

If you Google "rolling step stool" you'll a bunch of those designed for
the kitchen. I'm not sure of the casters could be used for what you're
making. But somewhere in between the kitchen and industrial ones has to
be a caster you could use on which you could swap out the springs to
work perfectly for your particular weight requirements.

Don't know if this would work for you but I have a setup on my drill press
that allows easy movement but grounding if I want it (turns out I never
bother grounding it). Set up...
1. A base for the casters
2. 2 - lumber pieces of appropriate size near the ends of the base and
hinged to it; the cross pieces need to be a bit greater than the caster
height in one cross section dimension, a bit less in the other
3. Attach a lever to one end of each cross piece. I used 3/4" ply, maybe 2"
x 12"
In use, when the cross piece is "up" (thin dimension horizontal to the
base),the casters touch the floor; when it is "down", the casters do not.

OK, cancel my drill press thingy. I kinda think finding a ready made
solution is going to be tough but how about this (I'm assuming you are
making the steps)?
1. a piece of ply with standard casters
2. box with bottom, 2-4 bolts through bottom
3. attach #1 to #2 bolts but with compression springs between the two.
4. sides and/or front back of the box almost to the floor
No weight on the box, it rolls easy; add weight and the springs compress
allowing the box/step sides and/or front back to hit the floor.

And further to that, I'm building a set of three steps about 20" high
that I can use to get my butt back onto my wheelchair when I fall on
the floor. The casters are for this step box ~ easy to pull around but
grounded when I climb up on it.

Thanks, I'm looking for something similar, only it's casters designed,
for a box or crate. Under normal conditions, it's easy to push on the
wheels. Then when weight is put on the box or whatever, it grounds
itself and can't be pushed easily anymore.

I have seen these on the bottom of round step stools. But the problem
