Slider Bush and Shaft Selection for Crank Slider

[jaakrob]

Hi,

I need someone to point me in the right direction please.

I'm designing a Crank System for a hand held tool. I'ts a simple design with the Crank providing reciprocating motion to a 6mm Diameter Shaft. The Shaft and bushing supporting it will have the following characteristics:

Shaft Stroke: 16mm
Shaft RPM: 2,400
Max Velocity of Shaft: 1.3 m/s
Max Acceleration of Shaft: 220 m/s^2
Lubrication: none/minimum

I need help deciding on a shaft/bushing arrangement that will allow this. specifically:

What type of bushing arrangement should i use?
What type shaft/bushing material should i use?
Are there any off the shelf products for this or should i be looking design myself?

thanks.

Suggestions:
#1 - Prepare a sketch to explain your setup. Words are inadequate.
#2 - You describe the motion well, but made no mention of loads, accuracy, or any other requirements.
#3 - Contact application engineers at known manufacturers of linear motion bearings such as PBC Linear, Igus, Thomson, IKO, etc. They are there specifically to answer questions like yours.
