Overview
The Festo EV-15/63-4 is a compact rodless clamping cylinder from Festo’s EV Series, engineered for single-acting pneumatic clamping operations. This hermetically sealed module delivers consistent workholding force across a 15 × 63 mm clamping surface with a 4 mm stroke, making it ideal for fixturing and positioning tasks in manufacturing automation. The diaphragm-equipped design ensures durability in harsh industrial environments while maintaining repeatable performance.
