About the Airtac SC80 Standard Cylinder SC80X50STC
The SC80X50STC is an 80 mm bore, 50 mm stroke double-acting tie-rod cylinder pre-configured with a built-in magnet and centre trunnion mount. It delivers 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 genuine AirTAC SC cylinder uses a PT1/8 port and an M20x1.5 rod thread. Its adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting the assembly from impact. The centre trunnion (F-SC80TC, supplied with TCM1 bracket) allows the cylinder to pivot, making it ideal for swinging or articulating loads.

Where the Airtac SC80 Standard Cylinder SC80X50STC Is Used
Part Diverter
The 50 mm stroke and centre trunnion mount allow a compact, pivoting action to divert boxes or components on a conveyor line, with sensors confirming retract/extend position.
Clamping Fixture
Delivers a controlled 2513 N clamping force at standard line pressure. The built-in magnet enables easy mounting of CMSG/DMSG sensors for cycle verification in automated welding or assembly jigs.
Linkage Actuation
The TC trunnion mount is purpose-built for linkages that require the cylinder body to pivot during the stroke, such as opening and closing a hopper gate or a heavy safety shield.
Is the Airtac SC80 Standard Cylinder SC80X50STC the Right Cylinder?
For applications needing slightly more force, stepping up to a 100 mm bore provides 3927 N push at 0.5 MPa. If space is tight and less force is acceptable, a 63 mm bore delivers 1559 N at the same pressure. This 50 mm stroke is well within the standard range, ensuring rapid availability.
When replacing an existing cylinder, match all five critical points: 80 mm bore, 50 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod design 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 SC80X50STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The pull force at 0.5 MPa is 2268 N.
Yes. The 'S' in the model code signifies a built-in magnet along the barrel. This allows you to directly clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the cylinder body to detect piston position without any additional brackets.
