Headset bearing help.

Re:

take it to your local bearing place somewhere on an industrial estate and they'll measure and match it. And vastly undercut the bike industry on price too

Should be a branch of Brammer near you somewhere, have you tried them?

Try Henderson Bearings in Ringwood, they have a complete range for bikes now (and a website).

Assuming you measured the bearing with an accurate Vernier, they are imperial designated sizes 1 3/4 and 1 5/16ths x 9/32. so nearest I can find is https://www.ebay.co.uk/itm/B542-2RSMAX- ... Sww9xZJTuk

and this from the excellent simplybearings

IMPERIAL!?!? much crazy! I would never have thought of imperial bearings even during the late 90s.

But you win the prize!!! Checking out B542-2rs even gives me the right thickness of inner and outer race. (it was measured with a vernier, but I wouldn't call it a good one...)


Unit Of Measure = IMPERIAL
Inside Diameter = 33.338mm
Outside Diameter = 44.450mm
Inner Width = 7.144mm
Outer Width = 6.350mm

Not cheap, but it saves another old headset!!!

I'm in your debt, sir.

No problem, glad to help. If the original had American origins, then imperial sizes are normal. Simply bearings uk give great service

Re:

Promising....

But you will need to know the chamfer angles too. I understood they are either 30 or 40 degrees.

 

[mdvineng]

the bearing in the Simply bearings link has the correct chamfer I believe from looking at it. head stock bearing chamfers are in the range of 30<45°
