The AirTAC Airtac SC32 Standard Cylinder SC32X140 is a genuine double-acting standard air cylinder with a Ø32mm bore and 140mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X140 is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 12 mm diameter piston rod and 21 mm adjustable air cushion make it well-suited for light automation tasks requiring a 140 mm linear stroke.
With a body length A of 140 mm, this genuine AirTAC cylinder provides a total extended length of approximately 280 mm. The PT1/8 port threads and standard TPU seals offer reliable operation in normal industrial environments from -20 to +70 °C.

The 140 mm stroke and 402 N push force at 0.5 MPa handle diverting and sorting of lightweight components on conveyor lines.
Compact 32 mm bore fits bench-top test fixtures and liquid handling systems where a clean, repeatable 140 mm linear movement is required.
Delivers 724 N at 0.9 MPa for holding small parts during assembly or light machining, with an adjustable cushion to reduce end-of-stroke impact.
Choose the SC32X140 for light pushing, clamping, or sorting where force demand stays within the 402 N (push at 0.5 MPa) envelope. If your application needs more force, step up to the SC40 series, which provides 628 N at the same pressure. For strokes of 300 mm or longer on a 12 mm rod, consider an external guide or a guided cylinder to protect the rod from bending under side load.
To replace an existing cylinder, match five points: 32 mm bore, 140 mm stroke, PT1/8 port thread, basic (no bracket) mounting, and confirm whether a magnet (-S suffix) is needed for sensors.
Quick checklist
At the standard 0.5 MPa operating pressure, the SC32X140 provides 402 N push force and 345 N pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
The SC32 is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is dimensionally shorter than ISO 15552 designs, so it is not a drop-in replacement. Match the 32 mm bore, 140 mm stroke, PT1/8 ports, basic mounting, and rod thread (M10x1.25) to ensure fit.
