Anyone knows the exact bearing size of these bearings? ID? OD? Width? Went thorough the spare lists from O.S it seems that the TZ are running the same bearings as the CV and the CV-R...

i think it's a funny size bearing... they usually do this so that you can't buy them from a bearing shop... the id is usually in mm (eg12/13/14/14.5mm). but it's the od that's the headache (eg 25.4/25.8mm)... i know the 0.21VZB shared the same bearings as the RB engines... not sure about the 0.12 size though. can try to ask sam at hobbylink if the RB bearings will fit...

of course, if have the original ones from toykar is easier that way...

2 cents...

I think what you are refering to is the tolerance of these bearings. Unless its a patented bearing of a different size, or not it should be available. The Matrix and TZ bearings are not of the same size and apparently there isn't any available at toykar. Anyone knows the exact size of the bearings?

hi,

the measurements of the bearings are not tolerances (eg. 25.8mm).. they are exact bearing size in od... tolerances for bearings are in microns, not a tenth of a mm... getting a 25mm or a 26mm from a bearing shop will not fit... i'm not sure if they can 'patent' a bearing measurement, but it's done delibrately so that other normal size bearings cannot fit... can drop by a bearing shop to find out more...

sorry that i didn't answer the last question as i really do not know the measurements of the bearings...

2 cents...

thanks.

Hi,

To get at least a figure about the OD of the bearing, open the rear cover of the engine then measure the internal diameter of the rear part of crankcase, as maikaitan said the id of bearing can be measured by measuring the OD of crankshaft.

just my 2cents....:-)

Here you go guys..

OS 12 TZ
Internal Bearing = 12(ID) X 21(OD) X 5(W)
Front Bearing = 7(ID) X 17(OD) X 5(W)

Hobbylink is selling the RB V12 front bearing which can be used for this engine as well but i'm not sure for the internal..
