Casters...

Some 20 years back we had a ‘desk’ chair built of cherry to match the corner desk we also had built at the same time… Well, the original casters failed, I tried another, also failed, but replaced them with these to protect the hardwood floors.

Local chain, not Lowes, had them in stock, worked fine, until they didn’t. One of the 2 front 2x2 logs cracked a bit, casters were loose so would fall out if the chair was lifted… Anyway I bought an extra pair, mostly because until just now I couldn’t find them online anywhere… 80 pound capacity each, 310# for the 4, so pretty sturdy, but because the stems in the front were loose, a problem… So, I had to drill them out a bit to install 3/4" hardwood dowels, I first had to fill the holes temporarily, then with a 3/4" Forstner bit, bored new holes for the hardwood dowels, 2" deep, I’ll cut these flush, once dry then new 3/8" holes for the new casters…

If they fail again, we’ll go back to the cabinet/furniture folks and maybe they could replace those front legs, DW loves that chair, hopefully I have solved it this time…

Fingers crossed…

I have used these

That 110 lb figure is per caster. I don’t know how these do on carpet, but they do not mark our prefinished, engineered hardwood floors. As undoubtedly know, there are difference caster stem sizes.

Casters set into wood present a challenge I haven’t faced.

I’ve replaced the wheels on two office chairs and the first thing I learned was that matching the stem is the place to start. And I mean match exactly. Mine had a sort of split ring in a groove that held them in, and of course the diameter had to match.

When I moved into my new place I was worried about damaging the hardwood floors. The casters I bought are gray, not black, and are supposed to be easy on hardwood. I still added floor protectors, though I often roll a wheel or two off onto the bare floor.

I just found my order, and the casters I bought, with what they describe as Thermoplastic Rubber Wheels.

I found that the split-wheel casters are harder to turn (easy to roll, harder to swivel), so they have extra stress on the pivot. A single point wheel will pivot on the axis more easily.

I just replaced two office chairs with casters like this: poly-rubber; they provide an exceptionally smooth glide.

You can also find them without the insertion rod, they come on a caster which screws into the chair leg with four screws (each) like this

GWP, I have similar casters on my own office chair, was concerned with harming the bamboo flooring here in my cave. Work well… I did have to watch for, find a chair with a metal base, a previous plastic base just wasn’t up to it, broke, took a divot out of the bamboo… Lesson learned…

I needed long stemmed casters for DW’s chair, the ones I pictured worked, I finin=shed it up today, so it’s back in service… A little fun placing, gluing the 3/4" dowels, then boring a 3/8" hole in the center for the stem holder…

Whew…

RH - Yes, those look similar to the ones I used… This is the 3rd set well 4th for the front two casters, I knew they were loose, put off fixing them, but now i think I’m all back on solid ground again…

GH - I didn’t find what I wanted at Amazon, probably because I had bought the earlier set locally, but since then I dod find them at Lowes, under a different brand, Titan…

Done, hopefully the final fix…
