The AirTAC Airtac SC32 Standard Cylinder SC32X25SH is a genuine double-acting standard air cylinder with a Ø32mm bore and 25mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X25SH is a compact double-acting tie-rod cylinder with a 32 mm bore and 25 mm stroke, delivering 402 N of push force at 0.5 MPa. Its 12 mm diameter piston rod and M10x1.25 rod thread suit light automation tasks where space is tight, and the 21 mm adjustable air cushion at each end smooths deceleration for consistent cycling.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, raising the operating temperature range to 0–150 °C, making it a reliable choice for hot environments or applications with aggressive media where standard TPU seals would degrade.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals allow this cylinder to operate reliably in autoclaves, sterilisation equipment, or drying ovens where ambient temperatures reach up to 150 °C.
With the built-in magnet, CMSG/DMSG sensors confirm end-of-stroke position in high-speed sorting gates or diverters, ensuring precise part ejection on packaging lines.
Ideal for small clamping or test fixtures in labs, the 25 mm stroke and 402 N force handle sample holding and micro-manipulation tasks with clean, filtered air.
Choose the SC32 bore for push forces up to 724 N at the maximum operating pressure of 0.9 MPa. If your application requires slightly higher force, stepping up to the SC40 bore provides 628 N at 0.5 MPa. For strokes of 300 mm or longer on this 12 mm rod, assess side loads carefully—an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear. When replacing an existing cylinder, match five points: 32 mm bore, 25 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No. The SC32X25SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centred. For load-holding applications, you must add an external rod lock, a pilot-operated check valve, or use a mechanical brake.
