Looking For Soft Bushing for Aerospace Application

Looking For Soft Bushing for Aerospace Application

Looking For Soft Bushing for Aerospace Application

(OP)
I am looking for a soft Bushing something other than metal. Such as a Rubber Flanged Bushing. Any Idea Welcome. Bushing vendors for aerospace applications?

RE: Looking For Soft Bushing for Aerospace Application

what country are you in? how big is the part? is it safety related? what rate? what loads?

Cheers

RE: Looking For Soft Bushing for Aerospace Application

Some motorcycles use Flanged Hard Rubber bushings in their motor mounts.
What is the intended purpose? Vibration isolation?

RE: Looking For Soft Bushing for Aerospace Application

I have been advised EDM machining is sometimes not allowed in aircraft parts.Can anyone tell me why? we are looking to modify a small servo piston 1/4" Dia. with a very small internal hole 012 Dia. and the part is 57HRC.Needless to say, that makes it very hard to drill and ream.

RE: Looking For Soft Bushing for Aerospace Application

"The EDM process is a thermal process that removes material by melting it away. It leaves behind a slightly altered surface which consists of a hard crust or recast layer, and a heat-affected-zone (HAZ) underneath which is usually softer than the base metal. In extreme cases, the recast layer can have micro-cracks and high levels of stress, which can lead to part failure under high levels of cyclic stress loading. The HAZ can also show signs of intergranular attack, as well as microcracking.

For these reasons, the application of EDM in aerospace parts is very carefully controlled and regulated."
