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?

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?

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.

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

    • Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.
    • Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using. 
    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
