LifelongOffice Chair Wheels Replacement Rubber Chair Casters for Hardwood Floors and Carpet, Set of 5, Stem Casters, Heavy Duty Office Desk Casters for Chairs to Replace Office Chair Mats - (Black)

There are days when the world refuses to move with you. The floor: a cold expanse of Andalusian tile. The chair: your trusted Herman Miller Aeron, on failing casters. But then, from a forgotten warehouse off the Aegean coast (or perhaps New Jersey), they arrived: five crystal wheels, their surfaces gleaming like glacier-fed lagoons at dawn. Chrome arms, slick as a Monaco roadster. Polyurethane so translucent I mistook them, for a brief and humbling moment, as frozen ice medallions from the future. I installed them barefoot. Reverently. They fit perfectly.These are not chair casters. These are the cufflinks of locomotion. A silent and elegant glide across space and schedule. The struggle against the tile is over. Victory is silent, sturdy, smooth, functional, and chrome-plated. Recommended.

These wheels are awesome! Easy to install! Ultra smooth! Just what I needed! I highly recommend !

I purchased these for my Herman Miller Aeron office chair when I started working from home about three years ago. The chair is almost 20 years old and when I brought it home I was worried that the original rigid plastic wheels would scratch my hardwood floor. So, I chose to replace them with these. I made the right choice. I LOVE THEM! I can’t quite explain how different they feel, but it’s like they have a very slight give that the rigid ones didn’t. It just seems more comfortable, especially when rolling. They handle the hardwood floor with ease and leave absolutely no marks. But my favorite thing about them is the reduced noise when I move. They are whisper quiet! Perfect for when I’m in Teams or Zoom meetings. Replacing the wheels was easy as pie; took less than five minutes. I would buy these again in a heartbeat, but I can tell they will last the lifetime of the chair so I won’t have to.

I purchased two sets of these casters in separate orders for two home office chairs we have. The prior plastic OEM casters were terrible. They were frozen and just scraped the chair mat. The stems on the new casters were easy to install in a few minutes. They continue to roll very freely from over 3.5 years of nearly daily use. I have not had to worry about any ball bearings spilling out. They are well-made and worth the purchase price.

The stock hard plastic casters that come on spkr cabs just don't seem to withstand rigorous load in/out; I've replaced all 4 casters on 2 Ampeg SVT-410HE's @least once w/ hardware store replacements. Even new wheels aren't that mobile on rough sufaces.Then I came across a great deal on a used Ampeg PR-410HLF. I've wanted to try one out forever and I really dug the sound, but obviously the weight is a real issue, and this one didn't come w/ casters(obviously broken and abandoned long ago), so out came the 2wheel dolly.Scrolling thru amazon, I found these heavy duty replacement casters for office chairs; they are literally rollerblade wheels on a swivel mount. Hard rubber wheels that are rated @650lbs each and garanteed not to scratch hardwood floors or break easily like plastic casters tend to. Since office chairs have 5 wheels you'll even have a spare. So I bought them, not thinking about checking shaft size(insert snicker here), they are a hair(hee hee) smaller than the stock metal inserts that come on the cab. So back to amazon to order the correct 7/16" inserts and they fit the existing mouting holes no problem. I installed the replacement casters, and now the thing moves like a damn skateboard, and thats not a big exaggeration bcs even on a slight incline, it WILL roll.Each wheel is rated @650 lbs apiece, I'm confident they'll outlast those stock plastic casters and you have a spare. I even put them on my pair of 410HE's although they aren't doing full time duty anymore, I still have to lift the PR410 by myself, so I'm sure I'll need them @ some point. Maybe a gig rig and a practice rig. I've had these for awhile now and it just occured to me it was prob time to share this solution. Peace Ya'll!👍

The wheels were very easy to install, just popped off the old ones and popped on these ones. It made my chair very quiet when rolling and I don't have to worry about scratches on my hardwood floors, however, there are a few things I wish I had known before buying. First, these new wheels unexpectedly raised my chair a few inches in height, so now my thighs are flush against the bottom of my keyboard drawer on my desk, making it very hard to work comfortably. I'm going to have to raise my desk, get a new desk that will fit, or go back to the old wheels... none of which are options I'm excited about.Also, if your floor is even remotely unlevel, your chair is gonna roll and it will roll often. The second I stand up (even if I don't push back against the chair to stand), my chair slides backward and hits the wall behind me. If I'm not centered directly in front of my desk, I will start rolling sideways in the direction my floor is slightly slanted without any prompting. Now, my floor is BARELY uneven—I'm talking about maybe a millimeter of a slant—and it's doing this, so these wheels must have little to no friction with the ground. I want to take it on the highway to see how fast I can get the chair going before they fall off, but I'm being told by my husband that it's a silly idea. We'll see.

I bought two sets of these casters in separate orders for two office chairs we have. The casters were basically frozen, the chairs were difficult to drag across the floor. The stems on the new castes were about 7/16 x 3/4 which matched my chairs. Easy to install using a flat blade screwdriver as a pry bar. Both chairs were fixed in about 7 mins each. And the roll very freely, and the ball-bearings around the stem makes it easy to change directions. Not cheap, but worth every penny!
