Pressure and piston area set theoretical force; pressure loss, friction, acceleration and a design margin must be considered before selecting a bore.<\/p>\n<h2>Push Force From Bore and Pressure<\/h2>\n<p>For extension on full piston area, theoretical force equals pressure multiplied by piston area. Use pressure expected at the cylinder during the working stroke, not the relief setting as though it were guaranteed continuous pressure.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Input<\/th>\n<th>Engineering question<\/th>\n<th>RFQ field<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Required push force<\/td>\n<td>What thrust is needed at the worst linkage angle?<\/td>\n<td>Maximum working load + geometry<\/td>\n<\/tr>\n<tr>\n<td>System pressure<\/td>\n<td>What pressure is available at the cylinder?<\/td>\n<td>Normal pressure + relief setting<\/td>\n<\/tr>\n<tr>\n<td>Colpo<\/td>\n<td>What travel is required?<\/td>\n<td>Stroke + retracted envelope<\/td>\n<\/tr>\n<tr>\n<td>Speed<\/td>\n<td>How fast must it move under load?<\/td>\n<td>Extend\/retract time or velocity<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Retraction Uses Annulus Area<\/h2>\n<p>Double-acting retraction uses piston area minus rod area. Retract force is lower and, for the same flow, retract speed is usually higher. Check both directions.<\/p>\n<h2>Check Rod Stability and Mounting<\/h2>\n<p>Long compression strokes can be limited by rod buckling before pressure rating. Effective column length changes with mounting. Side load or a misaligned clevis increases bearing and seal stress.<\/p>\n<h2>Translate Speed Into Flow<\/h2>\n<p>Required flow equals effective area multiplied by piston velocity.
