Washers/Bushings 1

[harrai]

Hi All:
I have steel axle(shaft)in aluminum part, and I doubt eventually corrosion might take place due dissimilar metals.SO in order to aviod this I am planning to use bushing to reduce corrsion but I am worried about that busing being soft material may not take the load and might fail to transfer the load.

Please any thoughts on this would be appreciated.

thanks

Uhm?

Select the bushing material and size appropriately for the load.

Depending on the application, temp and fitment - you might consider something like Bostik Never Seez. There are other comparable products, but these are the ones I have experience with. ISZ

Not sure, of your exact arrangement but.... as long as you treat one of the surfaces, say the aluminum via anodize then you shouldn't have a dissimilar metals issue.

Can you post some more specifics to the design? One suggesting is using a metal backed bushing like these

Make the bushing out of steel and have it cadmium plated.
