Earlier power clamps could operate at only 2000 to 3500 psi (pounds per square inch) fluid pressure. You needed large, bulky clamps with large internal cylinders to provide enough clamping force. SWIFTSURE components are designed differently, inside and out, to fit easily on fixtures. They work comfortably even at 7500 psi, letting you use much smaller clamps to get the same clamping force. Compact SWIFTSURE clamps open up new fixturing possibilities: you can now place clamps in tighter spots than before, and with the extra space, you can put more workpieces on a fixture (for example, six parts per cycle instead of only 4).
