Hi,
For swinging arm spindle and bushings, I do have room for tiny needle bearings 20mm/32mm. The present design, bushings and hollow steel spindle, worn out..

idea
*spindle of ally 6026

*bushing of bronze 5640

*seals and grease nipple

Do you think this will work or will seize?

Cheers,

[husky]

I think it would work,tho you might need the spindle to be steel .Never seen the effect of running alloy in a bronze bush,doesn,t mean it wouldn't work tho

Hard Anodised it might work, what are the properties of 6026 ? Most 6000 series Alloys are fairly low grade commercial. For strength normally 2014 or 7075 is used.

Thanks husky and Wayne,

*been recommended to stay with steel, but because of hollow, welding ends with threads is required..:-(

*yes, 6026 T6 is worse vs 7075 (T7?) or T8, but did bought 6026 of different diameters for multipurpose..welding and not/axis, spacers..

*Buy T7 or T8 seems like the best solution

*anodizing crossed my mind, the workshop who helps me offering hard and for bling ano, but do not know how long time the hard surface will last?

*Nikasil...

cheers,

Pat are you outside the UK by any chance? That material seems almost unheard of here. Sounds almost like freecutting ally. So probably not suitable no matter what you do with it.

Hard anodising at least at my platers achieves about 500 vickers hardness. Usually 50 micron thickness. Certainly good enough for a very famous brands motocross clutch baskets

But really a good steel is the way to go.

Why would a tubular steel axle need to have solid ends welded on to be threaded?
