About the Airtac SC80 Standard Cylinder SC80X1120STC
The SC80X1120STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 1120 mm stroke is within the 1500 mm maximum standard range for the 80 mm bore, making it a readily available configuration for long linear movements.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC80TC), which allows the cylinder to pivot during operation. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end ensure reliable deceleration for this long-stroke actuator.

Where the Airtac SC80 Standard Cylinder SC80X1120STC Is Used
Long-Stroke Material Transfer
Pushes or pulls heavy bins and pallets over an 1120 mm distance on conveyor lines, with trunnion mounting allowing the cylinder to swing as the load transfers.
Automated Welding Fixtures
Positions welding arms or clamps with a long reach. The centre trunnion mount handles the pivoting motion, while magnetic sensors confirm clamp open/closed status.
Grain Chute Diverter
Actuates a large diverter gate on agricultural handling equipment. The 4523 N force at 0.9 MPa moves heavy grain loads, and the adjustable cushion absorbs shock at stroke ends.
Is the Airtac SC80 Standard Cylinder SC80X1120STC the Right Cylinder?
Select the SC80 when your application requires between 2513 N and 4523 N of force. If a lower force is sufficient, stepping down to a 63 mm bore reduces the push force to 1559 N at 0.5 MPa. For higher demands, the 100 mm bore provides 3927 N at the same pressure.
For this 1120 mm stroke, managing side loads is critical. The 25 mm rod is susceptible to bending under lateral force when fully extended. Always use an external guide rail or rod alignment coupler to prevent bearing damage and ensure smooth operation. When replacing an existing unit, match five points: 80 mm bore, 1120 mm stroke, PT port thread, TC centre trunnion mounting, 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 SC80X1120STC FAQ
The theoretical push force is 2513 N at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is slightly lower due to the rod area, providing 2268 N at 0.5 MPa.
Ensure your existing cylinder matches these five specifications: an 80 mm tie-rod body, exactly 1120 mm stroke, PT (Rc) threaded ports, a centre trunnion (TC) mount with the TCM1 bracket, and a magnetic piston for barrel-mounted sensors. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
