plastic cage bearing quick question
Turbo Mini Forums

my 1st motion nose bearing have a plastic brown cage does this means that i have a smaller normal A plus bearing and tranfer case and dont have to spent 50£ im a new one??

right down the part number on here and i can tell you, the coluor of the cage means nothing

always looking for them bigger bunches of bannanas

if the bearing is ok you can get away with this one by....

teasing the rollers out of the plastic cage then teasing the plastic cage off

then with a small puller remove the inner metal race off the shaft

the above saves you some money

speak with simon from morspeed. he got hold of a few bearings that had a brass inner race. he sold me one for about 35 squid.

balls to the blower!!!

plastic caged bearings vs metal caged is nothing to get wound up or excited about.

30+ years ago it was because the polymer technology wasn't aound - so metal caged were eveywhere.

Today - metal cages are generally only specc'd out when there is a temprature requirement that would compromise a plastic cage. Hence metal is used.

Bearings numbers are: 2/LRJ15.8 for the turbo (big) bearing (IIRC), and 1/LRJ15.8 for the 'normal' one...

Good Info Dave.

Just to add a little more:
2/LRJ15.8 is a 12-roller design; the 1/LRJ15.8 is an 11-roller

just mesured the outer race diametre is... 42.97mm accordind to some older posts i have a turbo bearing... Not sure if i should be happy (since i doubted that i have a turbo box because some told me that i have an economy gesr set)
back to the point its goodby 50£????

Not if you purchase from BSL (Bearing Services Limited) - more like £30...

Personally - I'll always use the larger bearing. AustinRover didn't do anything they didn't have/want to - so why did they go to the expense of tooling up and using another bearing?
I recall it has a significantly increased dynamic capacity - something like 25% over the 11-roller version.

got a pic of the two types for a 'quick' check..

- though as TurboDave has said - count the rollers!

can pics be posted??

TTFN,
Dave

Yes they can - if you use the normal (not quick) reply button - then the 'smileys' table appears. The button on the top RHS is insert piccie. Press this - then insert the hyperlink into the popup (turn off popupstopper) and away you go!

just found a trader of nsk bearings (they bought RHP) here in portugal and in my town tomorow i will tell its availability and price.

ah - picture is on my pc: not on interweb... :
