Piston throw

[Alex N.]

Does the throw on pistons come in 1/2 inches: 3 1/2, 4 1/2, etc. when ordering from the manufacturer?

I'm not sure if you are referring to the bore, throw or pistion diameter, but from the dimensions you just threw out, I would say you are interested in the stroke. The Bimba order form has varying stroke lengths from:
- 1/2" up to 10" throw for 3/4" bore
- 1/2" up to 24" throw for 1-1/2" bore
- 1/2" up to 24" throw for 2" bore

The intermediate sizes vary with the bore diameter, however you get the picture.

You can only order the strokes listed on the pnuematics order form found at the back of the pnuematics guide. The smaller stroke sizes go up by 1/2 inch increments and then just increase by 1 inch increments. Look in the back of the pnuematics manual for the specific sizes.
