Ball Bearings For Turbo Where To Get

[joe blo]

Hi mates I want to get some bearings for my turbo. The size I need is 26x10x8. Does anyone know where I can get them? My local bearing shop only had one the said was rated to 12000 rpm but when I googled it it was actually 36000 rpm in oil.

What speed do they need to be good for?

When you get shaft play is it from the bearings?

have you talked to a turbo shop? They might be able to help you. I can't say for sure but I know some turbos can spin well over 150,000RPM so 36kRPM isn't much by comparison

Bearings are the least of your dramas. How are you re balancing your turbo? 1/4 of a gram gets VERY heavy when you spin it quickly! What turbo is it for? Most modern garretts are non rebuildable. Most are only available as a core (bearing, housings turbines etc, pre build, pre balanced)

If you need bush bearings, then I can get them easily through a local turbo supplier.

Shaft play which way? in out or up down?

[joe blo]

I can get it balanced but the guy doesn't have the bearings.

Has a tiny bit of in/out movement but I not sure if its from the bearings. The bearings actually look ok but I don't really know how to tell if there 100% good

If he cant source bearings, id think twice about getting him to balance it.

Ive done turbo balancing before and its a very specialised machine

You can't. Garrett make it very hard and or expensive to get replacements. That's one of the reasons the GCG rebuilds are so expensive. Try Hypergear - he will know if they can be got.

Is not normal to replace turbo bearings at home.

Especially when you don't know what you are doing.

Don't do it.

why,why,why Ben..i wanted to see how it turned out..lol

cheers

[hypergear]

what sort of turbo is it?

[joe blo]

il prob do it still mates. it not garrett. deffs fully serviceable.

[joe blo]

post is mainly to see if anyone knew about 26x10x8 ball bearings suitable for turbochargers

[scotty nm35]

Considering Stao above rebuilds turbo's for a living, it may pay to answer his questions...

Have you contacted the manufacturer?

[MJTru]

I wouldn't try rebuild it. Balancing is the main issue. As for the speed. 150k to 200k more than that is over spinning your turbo. Danger will Robinson danger. Lol

During the VNT CBB development the shaft speed of the SS2 Alpha have maxed out the gauge of 180,000RPMs around 5000RPMs, so by the end of the run of 7200RPMs it would be over 200,000RPMs.

The 12,000RPMs bearings don't work, they could be easily obtained, those were the first ones I've tried and Very nosy.

Apart from balancing, and shaft speed there are many other critical areas to be considered. It took me close to a year to workout all aspects and having it working reliably.

Yeah I've only ever rebuilt turbos for large diesel engines which only rev to about 2100rpm, and they were pretty heavy duty bush bearing turbos. Fair bit of screwing around getting everything right on the shaft then balancing the thing. This is why I gave my original comment. If he can't source bearings, I dont know if I could trust the final build of the turbo

Talk to Stao ^ ^ ^ ^ ^ ^ ^ ^

He definently knows his stuff, plenty of happy customers on here, myself included
