Converting Degrees to inches

Converting Degrees

I have a 6 inch shaft that is 4 feet long. I am using this shaft in a piece of machinery and have to hold .3 degrees from one end to another in a bearing. If i have to do this then how can i get .3 degrees converted over to tell me how many inches that is. i have converted to radians but am trying to get that to radians. Do i have all the measuremebnts i need ...Please help!!

6 inch diameter shaft
4 feet in length
need to hold .3 degrees from end to end.

What is that in inches (thousands)

Can you posta drawing or plan of the machine if you have?
Its almost impossible to imagine/ picture what you are speaking of

Re: Converting Degrees

brainey64,
I'm assuming that you need the deflection along the surface of the shaft. If that is the case, then deflection = Pi X diameter X .3/360 = Pi X 6 X .3/360 = 0.0157.
