About the Airtac SC80 Standard Cylinder SC80X260STC
The SC80X260STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm air cushion provide smooth deceleration for the 260 mm stroke, making it a robust choice for medium-duty linear tasks.
This configuration includes a built-in magnet for barrel-mounted sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation. The total extended body length is approximately 442 mm, with PT1/8 ports and an M20x1.5 rod thread.

Where the Airtac SC80 Standard Cylinder SC80X260STC Is Used
Conveyor Diverting
The 2513 N push force at 0.5 MPa easily handles medium-weight package diverters, with the trunnion mount allowing the cylinder to swing as the gate angle changes.
Clamping & Fixturing
Pivoting clamp arms in welding or assembly jigs benefit from the TC mount's ability to absorb angular misalignment, while the magnetic piston enables end-of-stroke sensor confirmation.
Chute & Gate Control
Controls a pivoting discharge chute on agricultural processing equipment. The 28 mm cushion absorbs the impact of a heavy gate closing, reducing noise and mechanical shock.
Is the Airtac SC80 Standard Cylinder SC80X260STC the Right Cylinder?
For higher force, the SC100 bore steps up to 3927 N at 0.5 MPa; for a lighter, more compact actuator, the SC63 provides 1559 N. The 260 mm stroke is well within the 1500 mm maximum for this bore, but ensure the rod is not subjected to side loads without an external guide, as bending stress on the 25 mm rod can cause premature seal wear.
To replace an existing cylinder, match five points: 80 mm bore, 260 mm stroke, PT port thread, centre trunnion (TC) mount, and the built-in magnet (-S). This genuine AirTAC SC unit is a tie-rod design, shorter than an ISO 15552 profile, and is not dimensionally interchangeable with them.
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 SC80X260STC 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.
No. The SC80X260STC is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. For load holding, you must add an external pilot-operated check valve or a mechanical rod lock.
