I think he's asking the difference in performance or why would you use an 8MM bearing compared to a 6mm bearing. I really don't know and it's a good question.

No. All bearing are good for high speed. Larger bearing can take more stress to support higher FPS. If you're gonna go bearings, go big or go bushings.

If you don't actually know, it's better not to say, than to give wrong information.

The larger the bearings, the more stress it can handle. The more stress it can handle, the stronger the spring you can use. Bigger is better, but don't forget that your gearbox needs to have bushing holes reamed to match the size.

all axel sizes are the same...the difference is in the Outer Diameter (OD) of the bearing. Obviously the size of the hole in the mechbox shell has to match.

Bearings are made up of itty bitty parts. 6mm bearings have smaller parts than 7mm bearings etc.etc.etc.. The larger the parts, the more durable they tend to be under heavy load.

6mm was seen as "fragile...and not durable enough unless you're doing a relatively low power high speed setup".

7mm was seen as the "min" size if you're going to use them

Then 8's, 9's and now 10's (I think, I haven't used them) came out relatively quickly.

I've run some pretty stiff setups in 8/9mm's...no issues with the bearings holding up. Gears/teeth/pistons going...but the bearings still look ok.

That said...there's good bearings...and shitty bearings. When you buy cheap guns...they skimp on these types of parts...after all describing it as having "8mm Bearings" sounds great doesn't it?

So if your gun was 6mm and you want to make it 8mm only the bearings and bushings need to be changed or does any other internal need to be upgraded.will this have any effect on reinstalling the gear box back into the gun ?

You cannot change the size of your bearings/bushings unless you change your gearbox shell or have you current gearbox shell bearing holes enlarged.
