supplyer for 17mm shaft

[diver]

I need 3 ft of 17 mm OD shafting and cant find any . Do any of you guys know of a supplyer here in the us. I searched and could not find any
thanks again

Diver, try Metric Specialties.

They have 17mm drill rod. If that won't do, they may have something else.

do you think drill rod can be used for a axle
thanks

 

[diver]

maybe some one knows if this will work for an axle. I did not realize that there is so many different rods this is the only one i can find at 17 mm
thanks again guys for bailing me out

How is the axle supported? Any welding? I assume this is for the trike you mentioned in an earlier post. Drill rod will harden in the area of a weld and might break. In the annealed state the axle might be whippy unless well supported.

I do have to do some mig welding to it, there will be 4 bearings within a 34 in span..two in the middle about 8 inchs apart and one on each end supporting the wheel and drive chain. the motor drive sprocket will bolt to the 24 inch wheel
thanks

I've mig welded to hardened steel without problems, in the sense that it welds fine, but I couldn't say how it affects the structural qualities of the steel.

You could unharden it by annealing (heating and quenching in either water or oil) which might make it more flexible. I would think most axles are hardened to some extent, as you want a bearing surface and little flex. Knowing if it is too brittle is the problem. Maybe someone here knows how to tell how brittle is too brittle, and whether it can benefit from annealing.

thanks, im going to order it today

Hello:
I am brand new to this forum,but when I was searching for some 17mm shaft myself yesterday,for a totally different application,I notice your request,and I may have found just what you are looking for.Personally,I would feel better about using this 1045,than drill rod,because I have had troublt in the past,with drill rod being quite brittle.
Hope this helps.

Since you've already ordered my suggestion may not help. Depending on where you live, good machine shop could be exactly what you need. Not only can they provide any size shaft you need they can do the welding required and be able to ascertain the hardness necessary for your project. If you add the safety and convenience factor into the equation it may not be as expensive as you think.
Good luck, Mike
