Bearing Sizes?

Hello All,
I have had a number of bearings go bad in my MR03 and wanted to order some more replacements. Before I started looking at bearings I measured what I have and the fronts measure 2X6X2.3mm. I then started looking around and on the Boca site they have two sizes listed 2X6X2.3 and 2X6X2.5mm. To make it more complicated I posted this questions on another site and was told that the 2.5mm width was what I should go with so now I am wondering what the correct size is.

Thanks.

Cheers,
Jim

The correct bearing size is 2x6x2.5 ( not 2.3 width)

The three bearing sizes used on Mini-Z's are:

2x6x2.5 - front wheels / also can be used on the rear left wheel instead of plastic bushing.
3x6x2.5 - rear axle/outer diff housing/ rear right wheel.
4x7x2 - PN style spur center bearing
------
If you come across an ultra thin Reflex Racing Spur (discontinued) they require a 4x7x2.5 center bearing

Gracias.....Wonder where the 2.3mm bearings came from? As I take front wheels on and off I will check they to make sure I have all the same size bearings on the inside of the wheels.

Cheers,
Jim
