STEALTHO Patented Rollerblade-Style Office Chair Wheels, Carpet, 5 Pack

I don't normally leave reviews but If you are on the fence about these , I found them amazing and very happy with my upgrade. My expensive ergohuman V2 wheels were unfortunately cheap plastic that broke over time leaving bits and pieces all over my floor.. this are a game changer .. super easy to just pull out old wheels and click these in , in a minute.I thought i might be rolling around the floor but it's been great and doesn't move unless you want it to . Gave my chair a new lease on life ! Super happy and I love the colour too

There are a lot of office chair castors using roller blade style wheels to choose from. They are essentially all the same and share all the same weaknesses, except these. The frame that carries the wheel is supported on the top and bottom with real caged thrust bearings riding on proper machined surfaces, this separates them from every other manufacturer in a big way.The other ones uses one row of lose balls riding on pressed steel races. Over time the pressed pivot pin gets looser and the lose balls end up falling out and ruining the castor, I've seen this happen on hundreds of office chairs and many times that again with castors using the same design for other applications. Between the time the pins get loose and the balls fall out you end up with a castor that won't turn when you try and move the chair, a real pain in the butt to say the least.These guys have eliminated the major failure point of every castor with the double thrust bearing design. It isn't revolutionary, this is the way thrust bearing should be used in an application like this. They also claim to use abec 9 wheel bearings, the 9 indicates that the bearing has very tight internal clearances between the balls and the races that they run. I can't imagine why they'd use these bearings, they are usually for high precision applications running at speeds of up to 30000 rpm. They are usually priced many, many times higher than a standard ball bearing so I can't say if these actually have them or not. I can feel resistance when I turn the wheel so they are tight. This is how they should be so don't expect them to spin freely. I read some review complaining that the wheels squeak or make noise. Don't be afraid to put some on the thrust bearings, just a couple drops top and bottom. They don't appear to be shipped with any grease or oil on them, likely done so it doesn't seep down onto carpets or floors and giving cause for bigger complaints. They are bearings, if they make noise oil them.These are by far the best office chair castor I've ever used, nothing else is even remotely close. The price tag is very reasonable considering what your getting compared to the other brands priced in the $30-$40 range. You get what you pay for in this case. If your not buying these just throw the first pair that you like the look of in your cart. The rest are all the same.

great wheels. Removed the hardwood plastic sheet and run these on the hardwood. much better, easier to clean the hardwood. No scuffs.

Item was great. If only I knew about it before, I would have reduced the damage to my wood flooring.

エルゴヒューマンのオフィスチェアのキャスターのゴムが劣化で割れてしまったため、代わりのキャスターとして購入。キャスターの付け替えは非常に簡単で問題なく設置できました。純正品と比べると1輪で大丈夫か不安でしたが、静穏性や滑りや回転なども申し分なく、安心して使用できています。見た目が大きく変わり、気分転換にもなります。純正のキャスターから変更の注意点として、純正のキャスターよりも高さが出るため椅子の座面の高さも少し高くなります。一番下げた位置で使っていた方は座面の最低高が上がってしまうので注意が必要です。
