Casters on equipment rack?

As one of my many Covid projects, I am building two new racks for my equipment and I am curious about whether using casters would adversely effect the sound quality. The racks are a "flexi" style using 1.25" walnut shelves and 3/4" black pipe, so they will be quite heavy (between 75 and 100lbs once loaded). I would really love to just roll them away from the wall to change anything and I can’t see any reason casters would be optional on speakers like Wilson and Tekton, but not okay on a rack. Components on the racks will be individually isolated using a combination of Isoacoustics Orea and Herbie’s dots. The floor is tile on a concrete slab. Casters are very high quality with rubber wheels and will be attached directly to the bottoms of the black pipe.

A  cantilever spring caster works very well. I added them to HEAVY bins, 500 lbs. They could go over an extension cord and not lock the wheel. You can add shocks too. Heavy tool boxes use them on rough concrete, floors, too. There are all kinds of sizes and they get pretty fancy. The spring load is adjustable on a few that I've seen. Or just 2 in the front or the back, Tip the object to hit the rollers. Just a thought..

I've got two systems, and the components for each are in Salamander racks on casters. Some would say the racks are, at best mid-Fi, but every time I have to access the back of a component I thank myself for making the decision to go with the casters.

This is a tip and move, HIGH cap...

Use 4 and tinker, look pretty solid, 3300lb cap.. Come in black and white..

You got an Idea what your looking for.

I'm working on mobile racks too, with RtR and TTs. Mine use to work really well too.
Spring loaded casters...Spring loaded TT. 
Roll it on a thick piece of carpet and let it settle

I am familiar with the casters you are referring to, but as much as we audiophiles like overkill, I am still considering practicality and esthetics in this equation. The casters I have shortlisted are high quality, German-made, 2", non-marking and rated at 300 lbs.

Good idea. I will have to consider something like that if I decide to perhaps have casters at the back and legs at the front. Definitely more stable than casters.
