I will Start it I have a really nice chair for my desk but like all office/desk type chairs the casters eventually peter out and need replaced. I found these wonders at Menards and yes I read the weight rating as I am a bigger guy in the 285-300 pound range and realize my weight breaks things that are not build for me. These casters are rated at 385 pounds static and 333 pounds rolling. Well above my weight Popped the old wore out casters out, popped these in righted the chair and sat down and all five of the them snapped and dumped me backwards out of the chair as they went. No I did not plop down just a normal move into sit position action. These are the parts from them I have found thus far, when they snapped parts and pieces when skidding every place. Looked Good on Paper total failure in application! Perhaps Chel can offer some insight into this fine feat of Australian Engineering And the warranty specifics on the bottom of the box. For the record Menards will exchange these for the exact same garbage. As I rub the Goose Egg on the back of my head from bouncing it off a counter as I went backwards to the floor...... I Give Slipstick a TOTAL JUNK RATING which is slightly higher than the State of Illinois Credit Rating
Local office supply has commercial grade as well at $60 bucks per set of 5. Was not looking to make an investment in the chair just put some functional wheels under it. All worked out well in the end the wheels on the Junk ones are great, so I took them apart and replace the wobbly wheels on the original set with the shafts and wheels from the new junk set. Rolls like a caddy again!
Noticed a change at the box stores lately, used to be Chinese junk was for example $10 for an item and quality was there for $30, US or German etc. Now the Chinese stuff is $30, sold by US companies and made overseas, quality is no longer available at any price unless you go to sources that sell to industry. Industrial is high quality, but for example in machine tooling the item may be 10 to 20 times as expensive.. Well worth it if you plan on a production run in the thousands, but out of the reach of the hobby person making 1 to 10 items. In many cases it prevents the creation of new firms as well. It is becoming every more like going to Las Vegas and taking a chance at a slot machine when you buy food, or any other items from the box stores or online. Even with name brands you don't know what you really are getting. My nephew bought out his father's Small Engine repair and sales shop, $500,000 or so a year gross. Most of the stock he ordered from the major manufacturers is either on back order, since last November with delivery expected in.March, or has been canceled. This is from suppliers that he and his dad have been dealing with for 30 years and with no questions about payment. They either don't have the product to ship or perhaps the small independent dealers have lost out in the allocation process and the limited amounts are going to the big boys. While selling a few less lawn mowers or chain saws would have a limited effect on Lowe's for example, it may well be that not having the stock to sell will put him out of business. The so called supply chain problems may well do to many small independent businesses the same thing that the virus did to the small independent retail food services, close them.
Suggest you check out the casters made with skate wheels. Similar to this, but in no way limited to this listing (just the first one I saw, on Amazon). https://www.amazon.com/dp/B01G643EU6/?tag=survivalmonke-20
Have something similar under a lot of my shop tools like drill presses, and band and table saws. Good casters. My Malfunction here though is not that there are better, rather it is that these did not work as advertised. My old casters are cast aluminum and had double steel rubber coated wheels. After 25 years the wheels wore out and got all wobbly and started falling off. The wheels and shafts on the junk set are actually of reasonably good quality... it is just everything around them that is total garbage. So the wheels and shafts are now in my old cast aluminum and working great. What I did not expect was for every one of the new casters to break on the first sit down! What I did expect was to use them for a week or two and then change the wheels and shafts over. Just kind of to busy with other stuff atm to do more than stick them in the holes and role....... errr crash. This did give me a reason to get in the A/C for a hour tinkering with them this afternoon and a break from the heat!
