About the Airtac SC80 Standard Cylinder SC80X1175STC
The SC80X1175STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore, 25 mm piston rod, and a long 1175 mm stroke, this model is built for applications needing extended linear travel with substantial force. The body length A is 182 mm, and the adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly at both ends.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise position feedback along the full stroke. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (part code F-SC80TC), allowing the cylinder to pivot and absorb misalignment in swinging applications. Standard PT ports (PT3/8) and TPU seals complete the build, operating reliably from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X1175STC Is Used
Long-Stroke Material Transfer
Pushes or pulls heavy bins and pallets across wide conveyor gaps, using the full 1175 mm reach and 2513 N force at standard line pressure.
Welding Fixture Clamping
The centre trunnion mount allows the cylinder to swing into position, applying up to 4523 N of clamping force on large automotive or structural weldments.
Grain Chute Diverter
Actuates a large diverter gate on a grain handling system. The built-in magnet with sensors confirms the gate is fully open or closed at each end of the 1175 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X1175STC the Right Cylinder?
Select the SC80 when the 50 mm bore's 1767 N force at 0.9 MPa is insufficient for the load. If your application demands higher thrust, the 100 mm bore provides 7068 N at 0.9 MPa. For this 1175 mm stroke, side-load management is critical: the 25 mm rod can bend under lateral forces when fully extended. Always guide the load externally with rails or rods, or consider a guided cylinder if the load is not constrained. For a direct replacement, match the 80 mm bore, 1175 mm stroke, PT3/8 port thread, centre trunnion (TC) mount, and the integrated magnet for sensor compatibility.
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 SC80X1175STC FAQ
The theoretical push force at 0.5 MPa is 2513 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The pull force on the retract stroke is 2268 N at 0.5 MPa due to the area of the 25 mm rod.
No. The SC80X1175STC is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of the stroke to reduce impact; it is not a locking or holding brake. To hold a load safely without live pressure, you must add an external rod lock or a pilot-operated check valve.
