About the Airtac SC40 Standard Cylinder SC40X150H
The AirTAC SC40X150H is a double-acting single-rod cylinder with a 40 mm bore and 150 mm stroke, built with high-temperature Viton (FKM) seals for reliable operation in environments from 0 to +150 °C. Its 16 mm diameter piston rod and PT1/4 port provide a balanced design for medium-duty pneumatic tasks, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa.
With a compact body length A of 142 mm and a 21 mm adjustable air cushion, this tie-rod cylinder decelerates the piston smoothly at stroke end, reducing impact noise and wear. The 150 mm stroke is a standard length within the 1200 mm maximum for this bore, making it a readily available configuration for industrial automation requiring consistent linear motion under elevated temperatures.

Where the Airtac SC40 Standard Cylinder SC40X150H Is Used
Autoclave & Sterilization
Viton seals withstand 150 °C steam cycles, making this cylinder suitable for actuating doors, clamps, or lifts in autoclaves and medical sterilizers.
Foundry & Heat Treatment
Operates reliably near furnaces and ovens where ambient temperatures degrade standard seals, controlling gates or material handling arms.
Hot Press & Molding
Delivers 1130 N of force at 0.9 MPa for pressing or ejecting parts in heated molds, where thermal stability is critical for consistent cycle times.
Is the Airtac SC40 Standard Cylinder SC40X150H the Right Cylinder?
Choose the SC40 bore when your application needs around 628 N of push force at 0.5 MPa; if you require more force, stepping up to the SC50 provides 982 N at the same pressure. For strokes of 150 mm, side loading is generally manageable, but always ensure the load is guided externally if any lateral force is present to protect the rod bearing and seals.
When replacing an existing cylinder, match five key points: the 40 mm bore, 150 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body mount unit), and the magnet option (this model has no built-in magnet). The Viton seal variant is essential for applications exceeding the standard 70 °C limit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X150H FAQ
The 'H' suffix designates Viton (FKM) seals, which shift the operating temperature range to 0 to +150 °C, compared to the standard TPU seal range of -20 to +70 °C.
This specific model (SC40X150H) does not include the '-S' magnet option, so reed or solid-state sensors cannot be directly mounted on the barrel. For sensor compatibility, order the SC40X150SH variant which includes a built-in magnet.
