Very strong. I used them under a car seat I'm using as an office chair. The whole setup plus myself is probably around 120kg and the wheels hold no problem. I can scoot around without issue and the wheels are very responsive.

Ordered these without realising the fitting came in different sizes. Of course I ordered the bigger size which simply didn't fit. Oh well. However they certainly looked sturdy well up to carry the chair to fit to. Back to the drawing board, start again.

excellent item fitted them on thursday to a parrot cage, and they work a treat, will certainly be ordering more in the near future, service was 1000 per cent a real pleasure, thank you very much

Great castors, I fitted them to an old heavy weight folding table for the garage/ workshop. Very solid and easy to move.Had to drill and tap some holes in the base, the threads are M12x1.75.

Put on a small lightweight job box with handful of small tools weighing about 50kg if even and 2 of the wheels completely collapsed after a week of moving the box a handful of times. Not recommended unfortunately

Brilliant, they were to replace small non breaking castors on a stool for me to get around on, in the caravan, now I have had to have my leg amputated. The original castor wheels were too small and kept snagging and tipping me off. These are great and much safer.

Easy to fit, run smoothly and freely. Using them on my 2 in1 sack truck in the garden, so great for heavy duty tasks moving planters, rocks and compost

Hi i bought 4casters about 2months ago and when I needed to mood the unit it collapsed and if you look at the pictures i have taken you can see why too different size ball brings luck for me noting in my home was damaged but it caused a lot of work for me as i am a 67 year old man but this product in my opinion is dangerous not a happy person at the moment.

purchased them to install them on Baby Bouncer and Other indoor furniture. Since installing them things are so easy to move around the house. Like the size of these wheels, as the bigger the size makes them easy to move on carpet. This is my 3rd purchase

i bought them to make my bandsaw easier to move. tyres and locks are good. only problem was finding a drill bit big enough to make the existing holes in the stand big enough for the castor bolt to go through, and no washers in the box required more to be bought as they are a large diameter. once fitted though they look and work great, raised the saw by an extra 3 inches and took moving the saw from a strain to a two finger ( not reccomended for safety) exercise. just a shame about the washers.
