Funny bearing size
yorkie_chris:
Evening all,
I've got here a water pump from a compair reavel air compressor, seized up solid.
Can't read any numbers off the bearing but it's a single row ball bearing, was a 2RS one.
It appears to be 1 3/8ths" ID (1.375"), but a very odd OD, 2.825" or 71.75mm.
Any ideas? I can't find a bearing anything like and I think the nearest fraction equivalent is 2 53/64" which does not seem likely!
Bearings with metric OD and an imperial ID? Can you get them?
As it stands I'll make a sleeve inside the pulley or bore it out, not sure yet.
Jasonb:
35mm (1.377")ID x 72OD is quite common, what are you measuring with?

yorkie_chris:
A blunt spoon and a bit of string, obviously. :Doh:
Jasonb:
In that case ARC should have them plus they sell sharp spoons so get one at teh same time

Not that it has any relevance whatever to your subject, but they do exist. Or did.
Burman gearboxes had some ... GB, BA, and BAP types IIRC.
Quite why, I have no idea. :scratch:
