Hopefully INA will be able to give me the dimensions of the bearings & I can see if I can find another source for them. :wink:

In the meantime, I've measured the lower cup & found some cheepo Chinese bearings I 'think' might fit. Only cost about £1.50 each delivered :shock: so no loss if they don't fit. But if they do, they're a standard size so more better'er ones can be purchased.

As I say- watch the space. (You could cross your fingers too if you like :D )

I've spoken to Hope & they can't help other than confirm that the bearings were a special order from INA.

So... email has been sent to INA to see if they can shed any light.

Watch this space. :D


could you post the bearing sizes OD x ID x W and where the 45° chamfer is?

Cheers.

I'll give them a call. I've now got a rather sad bottom cup with a good bearing in it. (cheers Dick :wink: )

Once I have removed it, I'll be able to measure it up & try to source another supplier, maybe these guys will come up trumps.

I also have one of these with a slightly poor lower bearing. The size is 30 x 42 x 7 which is a standard size. Such as these https://simplybearings.co.uk/shop/advan ... glebutton=

HOWEVER! There is a chamfered edge on only one inside face. This appears to be the unique feature.

I’ll probably go down the flush and repack route, though might experiment with a standard bearing and see if I can add a chamfer on the lathe.

get one with two chamfers as long as it will sit right, good luck turning bearing material in a lathe, needs to be ground with coolant.
