About the Airtac SC80 Standard Cylinder SC80X900STC
The AirTAC SC80X900STC is an 80 mm bore double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). With a 900 mm stroke and a 25 mm diameter piston rod, this model is built for mid-to-long linear movements in automated machinery. The adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly at each end of travel, protecting the end caps and reducing noise.
This specific code includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and a centre trunnion mount (TC) with the TCM1 bracket for pivoting applications. The body length A is 182 mm, giving an extended length of approximately 1082 mm. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports (PT3/8) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X900STC Is Used
Part Transfer
Pivoting on its centre trunnion, the 900 mm stroke moves heavy components between conveyor lines, with the magnetic piston confirming end-of-stroke via barrel-mounted sensors.
Clamping & Fixturing
Delivers up to 4523 N at 0.9 MPa to lock welding or assembly fixtures. The adjustable cushion softens the clamp impact, protecting delicate parts.
Bin Diverter
Swings a diverter chute in a sorting system. The trunnion mount handles the angular motion, and the long stroke provides the reach needed to guide product flow.
Is the Airtac SC80 Standard Cylinder SC80X900STC the Right Cylinder?
Choose the SC80 when your application needs more force than a 63 mm bore (1559 N at 0.5 MPa) but does not require the bulk of a 100 mm bore (3927 N at 0.5 MPa). For a 900 mm stroke, always check side-load conditions: a long, unsupported 25 mm rod can bend under radial force. Use an external linear guide or a guided cylinder to protect the rod bearing and ensure reliable service life.
For direct replacement, match five points: 80 mm bore, 900 mm stroke, PT3/8 port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility. This cylinder is a genuine AirTAC SC tie-rod design, shorter than an ISO 15552 profile and not dimensionally interchangeable with it.
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 SC80X900STC FAQ
At 0.5 MPa, 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 reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. For a correct replacement, match the SC series specifically, verifying the 80 mm bore, 900 mm stroke, TC trunnion mount, and magnet option.
