About the Airtac SC80 Standard Cylinder SC80X780STC
The AirTAC SC80X780STC is an 80 mm bore double-acting pneumatic cylinder delivering a substantial 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). With a 780 mm stroke, it suits medium-to-long linear movements in factory automation, built on a robust tie-rod design that is shorter than an ISO 15552 profile.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket (F-SC80TC), allowing the cylinder body to pivot during operation. The 25 mm diameter rod and 28 mm air cushion provide smooth end-of-stroke deceleration.

Where the Airtac SC80 Standard Cylinder SC80X780STC Is Used
Conveyor Diverters
Pivots a diverter arm on a packaging line, using the trunnion mount for smooth swinging motion and sensor feedback for end-of-stroke confirmation.
Material Handling Lift
Drives a pivoting lift table in a work cell, where the 780 mm stroke raises bins to an ergonomic height and the magnet confirms position.
Clamping Fixtures
Operates a heavy-duty pivoting clamp on a welding jig, with the trunnion absorbing rotational forces and the sensor ensuring the clamp is fully engaged.
Is the Airtac SC80 Standard Cylinder SC80X780STC the Right Cylinder?
The SC80X780STC suits applications needing a pivoting cylinder with position feedback. For higher force, step to the 100 mm bore (3927 N at 0.5 MPa); for a more compact footprint, the 63 mm bore offers 1559 N. At this 780 mm stroke, ensure the 25 mm rod is supported against side loads—consider an external linear guide or a guided cylinder if lateral forces are present. For replacement, match bore, stroke, PT port thread, TC mount, and magnet option exactly.
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 SC80X780STC FAQ
At 0.5 MPa, it delivers 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 4523 N.
Match the 80 mm bore, 780 mm stroke, PT port thread, centre trunnion (TC) mount with TCM1 bracket, and the built-in magnet (-S) for sensors. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC unit with identical specs.
