About the Airtac SC40 Standard Cylinder SC40X1400S
The AirTAC SC40X1400S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and an extended 1400 mm stroke, built for long-reach linear applications. The -S suffix denotes a factory-installed magnet, allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors along the tie-rod barrel for precise position feedback without external brackets.
At 0.5 MPa air pressure, this cylinder delivers 628 N of pushing force and 528 N on the pull stroke, with a maximum operating thrust of 1130 N at 0.9 MPa. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end help manage end-of-stroke deceleration, though the 1400 mm stroke exceeds the standard 1200 mm maximum for the 40 bore, making this a non-standard, made-to-order configuration.

Where the Airtac SC40 Standard Cylinder SC40X1400S Is Used
Long-Stroke Part Transfer
The 1400 mm reach moves components between distant conveyor stations or work cells, with the magnetic piston enabling end-of-stroke sensor confirmation for automated sequencing.
Automated Gluing or Dispensing
Drives a dispensing head across a wide panel. The built-in magnet allows multi-position sensing to control flow rate zones along the 1400 mm travel path.
Vertical Bin Pushing
Pushes lightweight bins or totes off a high shelf onto a gravity chute. The 528 N pull force retracts the rod, and the adjustable cushion softens the return impact.
Is the Airtac SC40 Standard Cylinder SC40X1400S the Right Cylinder?
Select the SC40 bore when 628 N at 0.5 MPa meets the load requirement; if higher force is needed, step up to the SC50 bore which provides 982 N at the same pressure. For this 1400 mm stroke, the long unsupported rod is susceptible to bending under side loads—always use an external linear guide or rod support to prevent bearing damage and ensure reliable cycling.
For a direct replacement, match five key points: 40 mm bore, 1400 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC40 tie-rod unit with the same configuration.
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 SC40X1400S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 628 N pushing out and 528 N pulling in. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. The 1400 mm stroke is a non-standard, made-to-order length. You must also use an external guide rail for such a long stroke to protect the 16 mm rod from side-load bending.
