Engineering calculators
Size it before
you spec it.
Four sizing tools that run the same math our configurator does — bore force, rod buckling, speed from flow, and seal selection. No sign-up, no email wall, no spreadsheet. The formula is right next to the answer.
Sizing guidance, not final engineering. Every WestCraft build is reviewed by a human engineer before we quote it.
Force
Push & pull force
Extend and retract force from bore, rod, and system pressure. The first number every cylinder job needs.
Open tool →StructuralRod buckling
Euler critical load and safety factor for a loaded rod, with the four end-condition K factors explained.
Open tool →MotionCylinder speed from flow
Extend and retract speed and full-cycle time from the flow your pump delivers.
Open tool →SealsSeal temperature selector
Match Buna-N, polyurethane, or FKM (Viton) to the temperature range your fluid actually sees.
