Where can I get smaller chair wheels from?

I bought some replacement wheels for a kneeling chair I have.
The metal insert into the hole is too fat.

I'm assuming the widths are standard and I just got the bigger one.
Does anyone know what size I need to get?

Thanks.

 

Measure the hole diameter and find suitable ones.
Your question is very vague and gives no information such as brand of chair, are the wheels fixed or swivel type, are they 'wheels' or castors etc.
We really do need as much info as possible when asking these sort of questions.

 

I recently replaced a broken wheel on my pasture topper, with a wheel from these people:
https://www.brauer.co.uk/wheels-castors-r2.aspx
They were extremely helpful, and they have a large variety.

 

Post some pictures then we can see your problem.

 

This is what I have

Top 2 are broken

Really bad quality wheels

Would much prefer different wheels

 

Do you have a flat surface to fix new castors to?
Can you drill out the holes to a bigger size to take your new castors?

 

Thanks for the replies guys. Haven't been able to reply until now.

@Bobby Dazzler I can't just make holes bigger. All wheels I have seen have a groove cut on the shaft - this I assume is what lets it move freely.
I'd somehow have to add the same inside catching mechanism - in which case, I might as well make a new chair. LOL.

I'm trying to order the wheels from China. They cost a lot there - not as much as the website you referred to. Might start selling the wheels. LOL.

 

OM2 what is it that is too big?
IS the metal shaft that goes into the chair itself too big?
Or are you trying to put new wheels onto the wheel frame itself?

There are plenty of replacements available online, just measure the ones you got and query the sellers first.

 

@mattylad trying to put new wheels into a frame.
There are sellers. But... I might as well buy a new chair - the cost of the wheels is too much!

 

The complete wheel is about £3-4 each upwards on ebay.

How much are you seeing them costing?

Why not just browse the local skips/offices/industrial areas for an old office chair thats been thrown out? I see many that would have donor wheels.

 

@mattylad Send me a link to the wheels you think it is.
Definitely not £3-£4.
I've become a semi expert on these damn wheels. There's many different sizes. That's the problem. I bought from amazon and had to return because too fat.
I only need just one actually! Happy to pay £3-£4.
Send me an item number if you can get.

 

NO, do your own research.
Ask the seller if the diameter is correct.

Stop trying to replace part of the wheel and replace it all.
