About the Airtac SC80 Standard Cylinder SC80X1150STC
The SC80X1150STC is an AirTAC double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion are sized for robust mid-range industrial tasks, while the 1150 mm stroke provides extended linear reach within the standard 1500 mm maximum for this 80 mm bore.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-position sensing without external brackets. The centre trunnion mount (TC) ships with the TCM1 bracket (F-SC80TC), allowing the cylinder to pivot and self-align in swinging load applications.

Where the Airtac SC80 Standard Cylinder SC80X1150STC Is Used
Long-Reach Part Transfer
The 1150 mm stroke moves heavy components between distant conveyor stations, with the trunnion mount absorbing any slight misalignment during the swing.
Automated Welding Jigs
Clamps and positions large weldments with 2513 N of force at 0.5 MPa, while the magnet allows sensors to confirm clamp closure before the welding cycle starts.
Pallet Dispenser Pushers
Pushes tall stacks of pallets or bins with a controlled, cushioned stroke end, preventing damage to lightweight containers.
Is the Airtac SC80 Standard Cylinder SC80X1150STC the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If your load requires more power, step up to the 100 mm bore which offers 3927 N at the same pressure. This 1150 mm stroke is within the standard range, but always verify that the total extended length (body length A of 182 mm + 1150 mm stroke) fits your machine envelope.
At this stroke length, side loads on the 25 mm rod can cause bending or accelerated bearing wear. For any stroke of 300 mm or more, use an external guide rail or a guided cylinder if the load is not perfectly axial. To ensure a correct replacement, match five points: 80 mm bore, 1150 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S) 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 SC80X1150STC FAQ
At 0.5 MPa, 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 reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X1150STC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a load safely without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
