About the Airtac SC80 Standard Cylinder SC80X890STC
The AirTAC SC80X890STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). With an 80 mm bore and a long 890 mm stroke, this model is built for applications requiring substantial linear travel and force, such as material handling or large gate actuation. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation—ideal for swinging loads. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, protecting the end caps during high-cycle applications. The total extended body length is approximately 1072 mm (182 mm body length A + 890 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X890STC Is Used
Long-Stroke Material Handling
The 890 mm stroke and 2513 N push force efficiently transfer heavy components between distant conveyor stations or lift mechanisms, with the trunnion mount allowing the cylinder body to pivot freely.
Automated Welding Fixtures
Clamp and position large weldments with consistent force. The built-in magnet enables precise position feedback via CMSG sensors to confirm clamp engagement before the welding cycle starts.
Diverter Gate Actuation
Operate large diverter gates in chutes or sorting systems. The adjustable air cushion decelerates the heavy gate at each end of the 890 mm travel, reducing impact and noise in high-cycle logistics hubs.
Is the Airtac SC80 Standard Cylinder SC80X890STC the Right Cylinder?
Select the SC80 bore when your application needs between 628 N (SC40) and 982 N (SC50) of force at 0.5 MPa, stepping up to this 80 mm bore for a robust 2513 N. For strokes approaching 890 mm, ensure the rod is protected from side loads; an external guide or guided cylinder is strongly recommended to prevent rod bending and premature bearing wear. The centre trunnion mount is ideal for pivoting applications, but verify the trunnion position is correctly set for the mass and speed of your load.
For replacement, match these five points exactly: 80 mm bore, 890 mm stroke, PT port thread, centre trunnion (TC) mounting with F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with those standards.

- ✓ 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 SC80X890STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes, for any stroke over 300 mm, especially 890 mm, side loads can cause the 25 mm diameter rod to bend or damage the rod bearing. An external guide rail or a guided cylinder is strongly recommended to absorb lateral forces and ensure long service life.
