Think its normally 12mm thick and 42mm diameter?

Gary72:
Right got some sitting on my desk, (Thanks Mr.Chubs) the bearing no. is R12-RS.
None on UK ebay, like someone said above US imperial bearings, could ship 50 in for a about a £1 a bearing :shocked: Alans ask's £16 for 2 bearings and a spacer tube or about £19 for a coloured Mid BB kit.
I am going to try my local bearing shop. I have had a look on the net. Searched for R12 2RS

Be sure to buy yourself german, british or japanese bearing NOT chinese and they'll last a whole lot longer......  Last time I got some I think they were about £8 each for top quality ones   :)

steve:
try midland bearings, for they are the cheapest bearing supplier in the whole world

and when you ring up, they know what you are talking about


especially when you can now cross reference the quoted bearing number with their listing
r12 2rs
http://www.midlandbearings.com/Rseries.htm

so when you ring up say
-hello, I would like to purchase some 'R' series bearings
i'd like 'x' amount of R12 2 RS please

they will say, ok thats the 3/4 'bore' = 'i-d'=inner dimension/  1-5/8  o-d ,= outer dimension / 7/16 overal width.

you say yes please, thank you.

oh and with regards the spacer doobery, you simply find a bit of old tubeing, that has a bore of 19.050 - 3/4 inch, buy a 2.99 pipe slice or pipe cutter, and make 10
-plus you can 'dial your bb in, so the bearings won't crush - ie old seat post tube 22.2, which is an imperial measure ment has the 3/4 inner bore

-plus if you go to a motor factors, you can buy ''cam bucket shims' with the 3/4 bore - id' and get the chain line stupidly correct as they are o.osmiidge plus the innner spacer tightness can be gotten rid of

ok so i am bored and can't sleep, :LolLolLolLol:

lazychubs:
