About the Airtac SC40 Standard Cylinder SC40X1150SN
The SC40X1150SN is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1150 mm stroke suit long-travel linear tasks where a compact tie-rod body is preferred. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for rod-position feedback.
This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, helping to decelerate the piston quietly. NBR seals are fitted, and the total extended body length is approximately 1292 mm (body length A of 142 mm plus the 1150 mm stroke).

Where the Airtac SC40 Standard Cylinder SC40X1150SN Is Used
Long-Reach Part Transfer
Moves components across a wide conveyor gap or between parallel lines. The 1150 mm stroke and sensor-ready magnet support full extension and retraction confirmation.
Automated Gluing or Dispensing
Positions a dispensing head along a long linear axis. The 628 N push force at 0.5 MPa handles moderate tooling weight, while NBR seals suit standard shop air.
Vertical Door or Hopper Gate Actuation
Opens and closes a tall access door or material gate. The tie-rod design is field-serviceable, and the adjustable cushion reduces end-of-stroke shock.
Is the Airtac SC40 Standard Cylinder SC40X1150SN the Right Cylinder?
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If a shorter, more rigid setup is acceptable, the 32 mm bore SC32 series offers 402 N. At 1150 mm stroke, the 16 mm rod is relatively slender; avoid unguided side loads that can bend the rod or damage the bearing. Use an external linear guide or a guided cylinder for offset loads. When replacing, match bore (40 mm), stroke (1150 mm), PT1/4 port thread, the -S magnet option for sensors, and the NBR seal material.
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 SC40X1150SN FAQ
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. 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, so CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position.
