About the Airtac SC40 Standard Cylinder SC40X150S
The SC40X150S is a double-acting pneumatic cylinder with a 40 mm bore and 150 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter piston rod and PT1/4 port provide a balanced power-to-size ratio for medium-duty linear tasks.
This model includes the factory-installed -S magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion at each end decelerates the piston smoothly over 21 mm, reducing noise and wear in repetitive cycling applications.

Where the Airtac SC40 Standard Cylinder SC40X150S Is Used
Material Handling Gates
The 150 mm stroke and sensor-ready magnet make this cylinder ideal for actuating diverter gates or stops on light to medium conveyor lines, where end-of-stroke confirmation is required.
Clamping & Fixturing
With 628 N of push force at standard line pressure, the SC40X150S provides consistent clamping for CNC fixtures and assembly jigs, with magnetic sensors verifying the clamp position.
Packaging Presses
Delivers a controlled 150 mm linear stroke for pressing, labeling, or stamping in packaging machinery, where the adjustable cushion protects delicate product contact.
Is the Airtac SC40 Standard Cylinder SC40X150S the Right Cylinder?
Choose the SC40 when your application needs roughly 600-1100 N of thrust; if you require more force, step up to the SC50 bore which provides 982 N at the same 0.5 MPa pressure. For strokes of 300 mm or longer on this 16 mm rod, evaluate side-load conditions carefully—an external guide or a guided cylinder is recommended to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 40 mm bore, 150 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This tie-rod SC design is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with that standard.
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 SC40X150S FAQ
At 0.5 MPa the cylinder produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing.
