About the Airtac SC40 Standard Cylinder SC40X980S
The AirTAC SC40X980S is a tie-rod double-acting cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). With a 40 mm bore and a long 980 mm stroke, it is suited for material transfer and lifting applications requiring extended reach. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration at the end of travel.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The standard PT1/4 port and TPU seals suit filtered air systems operating from -20 to +70 °C.

Where the Airtac SC40 Standard Cylinder SC40X980S Is Used
Long-Reach Material Transfer
The 980 mm stroke moves parts between distant conveyors or workstations, with sensor feedback confirming full extension and retraction.
Automated Sorting Gates
Operates diverters or gates in packaging lines, using the built-in magnet for precise end-of-stroke detection at high cycle rates.
Vertical Lift Assist
Provides 628 N of push force for lifting and lowering light to medium payloads on vertical carriage systems.
Is the Airtac SC40 Standard Cylinder SC40X980S the Right Cylinder?
For applications needing more force, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If a shorter, more compact footprint is acceptable, the 32 mm bore SC32 series offers 402 N. When replacing this cylinder, match five points: 40 mm bore, 980 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
At 980 mm stroke, the unsupported rod length is significant. Side loads or off-axis forces can cause rod bending and premature bearing wear. Use an external guide rail or rod-alignment coupler to protect the rod and seals, or consider a guided cylinder for applications with inherent lateral forces.
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 SC40X980S FAQ
At 0.5 MPa the push force is 628 N and the pull force is 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, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp onto the barrel for contactless position detection.
