Re: calculating cylinder length from stroke

There isn't really a general rule of calculating the length of the cylinder, because the base dimensions vary by manufacturer, style of cylinder, bore size, and mounting options.

You will need to look through the Bimba catalog with the link provided above, and find the specific style of pneumatic cylinder that you want. In there, you will find exact base dimensions of that specific style of pneumatic cylinder, and you just add on the length of your stroke as dictated in the dimensions.


EDIT: The "Added per Inch of Stroke .15" is used for calculating the weight of the cylinder.
