\n& Selection Guide
\nForce \u00b7 Bore \u00b7 Stroke Calculation<\/span><\/h1>\n

Selecting the wrong bore size is the most expensive lift cylinder specification error \u2014 a cylinder that is too small fails to generate required force; one that is too large wastes energy and demands a larger, more expensive hydraulic power unit. This guide walks through the complete sizing methodology: load analysis, force calculation, bore selection, stroke determination, and pressure rating \u2014 with worked examples for the most common application types.<\/p>\n
