About the Airtac SC80 Standard Cylinder SC80X804STC
The SC80X804STC is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa) from its 80 mm bore. With an 804 mm stroke, a 25 mm diameter piston rod, and a 28 mm adjustable air cushion at each end, it handles mid-to-long linear moves where controlled deceleration is essential.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion (TC) mount with the TCM1 bracket (F-SC80TC) for pivoting applications. The body length A is 182 mm, giving an approximate extended length of 986 mm. Seals are standard TPU for -20 to +70 °C operation with PT ports.

Where the Airtac SC80 Standard Cylinder SC80X804STC Is Used
Long-Stroke Part Transfer
The 804 mm stroke and 2513 N push at 0.5 MPa move heavy components between conveyor stations. The centre trunnion mount allows the cylinder to pivot as it extends.
Automated Welding Fixtures
With a built-in magnet for end-of-stroke sensing and adjustable cushioning, this cylinder positions welding clamps or shuttles accurately in automated cells.
Pallet Dispensing Systems
Delivers the force and stroke to push or lift pallet stacks in material handling lines. The trunnion mount absorbs alignment shifts during long travel.
Is the Airtac SC80 Standard Cylinder SC80X804STC the Right Cylinder?
Choose the SC80 bore when your load needs roughly 2513 N at 0.5 MPa; stepping down to a 63 mm bore gives about 1559 N, while moving up to a 100 mm bore provides 3927 N. For this 804 mm stroke, confirm the rod is adequately supported against side loads—long unsupported strokes on a 25 mm rod can bend under offset loading; consider an external guide or a guided cylinder if side forces are present.
When replacing an existing cylinder, match five points: 80 mm bore, 804 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X804STC FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80 is a double-acting cylinder that does not lock or hold position when pressure is exhausted or the valve centres. If load holding is required, add an external rod brake, a pilot-operated check valve, or a mechanical lock.
