About the Airtac SC80 Standard Cylinder SC80X340TC
The SC80X340TC is an 80 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the 0.9 MPa maximum operating pressure. With a 340 mm stroke and a 25 mm diameter piston rod, this cylinder is well-suited for medium-duty linear tasks where a pivoting mount is required.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation and absorb angular misalignment. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. Ports are PT1/8, and the standard TPU seals provide an operating temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X340TC Is Used
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, making it perfect for actuating diverter gates on conveyor systems where the load path changes angle.
Clamping & Fixturing
Delivering over 4500 N of clamping force at 0.9 MPa, this cylinder provides the secure, repeatable holding power needed for robust manufacturing jigs and fixtures.
Packaging Machinery Linkages
The 340 mm stroke and pivoting trunnion mount suit complex mechanical linkages in packaging equipment, such as carton folding or product pusher arms.
Is the Airtac SC80 Standard Cylinder SC80X340TC the Right Cylinder?
For applications requiring a pivoting mount, the SC80X340TC with its centre trunnion is ideal, allowing the cylinder body to swing. If a rigid, fixed installation is preferred, consider the basic or foot-mounted (LB) variants. When the 2513 N force at 0.5 MPa is insufficient, stepping up to the 100 mm bore (SC100) provides 3927 N; for a lighter, more compact solution, the 63 mm bore (SC63) offers 1559 N.
At a 340 mm stroke, the 25 mm rod is robust, but any significant side loading must be managed with external linear guides or a guided cylinder to prevent rod bending and premature bearing wear. For direct replacement, ensure the new unit matches this model's 80 mm bore, 340 mm stroke, PT1/8 port thread, centre trunnion (TC) mount with TCM1 bracket, and the absence of a magnet.
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 SC80X340TC 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 SC80X340TC is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. For load-holding applications, you must add an external rod brake or a pilot-operated check valve.
