Square Pancake® II air cylinders meet the same standards of compact air cylinder quality as the Original Pancake and the Pancake II families. These direct interchange air cylinders in square form provide effective output motion with short strokes in a compact design.
Construction features include an impact-resistant interchangeable cylinder barrel made from high-strength composite and a self-lubricating cylinder wall. The smooth interior minimizes heat buildup, keeps friction low and prevents stick-slip that can hamper metallic cylinders. The stainless steel piston rods are plated with hard chrome to extend the lifetime of the cylinder, and the rod-bushing’s non-metallic high-performance composite provides high load-bearing capacity and resists harsh conditions.
The Square Pancake family is available in five standard styles and also includes a non-rotating series for applications requiring the load to stay in a fixed orientation during its linear movement. SND Series double-acting air cylinders come with two piston rods built into the cylinder head. The twin rods are bound by a rod end toolbar to hold the piston securely in place. This construction keeps the rods working in tandem, prevents parts from rotating around the rod axis and provides a convenient mounting surface for additional attachments.
