About the Airtac SC80 Standard Cylinder SC80X120STC
The SC80X120STC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 120 mm stroke. This configuration produces a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) that includes the TCM1 bracket (part code F-SC80TC). The trunnion allows the cylinder body to pivot, making it ideal for swinging loads. The adjustable air cushion at each end decelerates the 120 mm stroke smoothly, with a cushion length of 28 mm.

Where the Airtac SC80 Standard Cylinder SC80X120STC Is Used
Part Diverter Gates
The 120 mm stroke and pivoting trunnion mount allow this cylinder to actuate flipper gates on conveyor lines, reliably sorting packages with 2513 N of force at standard line pressure.
Clamping & Welding Fixtures
With a built-in magnet for end-of-stroke sensing, this cylinder confirms clamp position in automated welding cells, applying up to 4523 N of holding force at 0.9 MPa.
Hopper Door Actuation
The centre trunnion mount handles the arcing motion of a hopper discharge door. The 25 mm rod and 28 mm cushion absorb the shock of the door reaching its open position.
Is the Airtac SC80 Standard Cylinder SC80X120STC the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC series provides 3927 N of push at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore delivers 1559 N at the same pressure. The centre trunnion mount is the correct choice when the cylinder must pivot during its stroke; ensure the mounting bracket is secured to a rigid surface that can handle the reaction torque.
When replacing an existing cylinder, match five key points: 80 mm bore, 120 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensor compatibility. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X120STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder delivers 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes. The -S suffix in the model code SC80X120STC indicates a built-in magnet is installed on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel for contactless position detection.
