About the Airtac SC80 Standard Cylinder SC80X920S
The AirTAC SC80X920S is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. Its 80 mm bore drives a 25 mm diameter piston rod through a 920 mm stroke, with an adjustable air cushion (28 mm length) at each end to decelerate the load smoothly.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 182 mm, giving a total extended length of approximately 1102 mm. Operating on filtered air at 0.15–1.0 MPa, the TPU/NBR seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X920S Is Used
Long-Reach Part Transfer
The 920 mm stroke and 2513 N push at 0.5 MPa move components between distant conveyor stations. The built-in magnet enables end-of-stroke confirmation with CMSG sensors.
Palletising Pushers
Pushes finished goods onto pallets with consistent force. The adjustable cushion protects the load and cylinder at the end of the long travel.
Automated Assembly Feed
Advances sub-assemblies through a multi-stage fixture. The -S magnet allows the controller to verify full extension and retraction at each cycle.
Is the Airtac SC80 Standard Cylinder SC80X920S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N push at 0.5 MPa, while the 63 mm bore SC63 offers 1559 N if a smaller, lighter cylinder is preferred. At a 920 mm stroke, the 25 mm rod is susceptible to bending under side loads; use an external linear guide or a guided cylinder to protect the rod bearings and seals.
When replacing an existing cylinder, match five points exactly: 80 mm bore, 920 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic mounting configuration. This SC80X920S is a genuine AirTAC tie-rod cylinder—shorter than an ISO 15552 profile—so it is not a drop-in replacement for ISO 15552 units.
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 SC80 Standard Cylinder SC80X920S FAQ
At 0.7 MPa (7 bar) the SC80X920S generates 3518 N of push force and 3171 N of pull force, based on the official AirTAC thrust table for the 80 mm bore.
No. The SC80X920S is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
