About the Airtac SC80 Standard Cylinder SC80X1020STC
The SC80X1020STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa), driven by a 25 mm diameter piston rod. This model features a non-standard 1020 mm stroke, extending the total body length to approximately 1202 mm, making it suitable for long-reach linear tasks.
Equipped with a built-in magnet (S-suffix) for direct mounting of CMSG/DMSG/EMSG sensors, it also includes a centre trunnion mount (TC-suffix) with the TCM1 bracket for pivoting applications. The adjustable air cushion (28 mm) decelerates the piston at stroke ends, protecting the end caps during high-speed operation.

Where the Airtac SC80 Standard Cylinder SC80X1020STC Is Used
Long-Stroke Material Pusher
The 1020 mm stroke and 2513 N force at 0.5 MPa efficiently push large boxes or pallets across wide conveyor sections, with the trunnion mount allowing the cylinder to pivot as it moves the load.
Welding Fixture Clamping
Delivers consistent clamping force for large weldments. The built-in magnet enables sensor feedback to confirm clamp position, while the centre trunnion allows the cylinder body to swing into place.
Grain Chute Diverter Gate
Operates a large diverter gate in agricultural processing. The non-standard long stroke provides full gate travel, and the adjustable cushioning softens the impact at each end of the cycle.
Is the Airtac SC80 Standard Cylinder SC80X1020STC the Right Cylinder?
This 80 mm bore cylinder is ideal for medium-to-heavy linear applications. If your force requirement is lower, consider stepping down to the 63 mm bore (1559 N at 0.5 MPa) for a more compact footprint. For heavier loads, the 100 mm bore offers 3927 N at 0.5 MPa. The 1020 mm stroke is non-standard; always verify rod buckling and side-load limits.
For a stroke exceeding 300 mm, side loads become a critical concern. The long, unsupported 25 mm rod can bend under lateral force. Use an external guide rail or a guided cylinder assembly to prevent rod bearing damage and ensure linear accuracy. For replacement, match the 80 mm bore, 1020 mm stroke, PT port thread, centre trunnion (TC) mount, and the built-in magnet (-S) feature.

- ✓ 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 SC80X1020STC FAQ
The theoretical push force is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on retraction is 2268 N at 0.5 MPa due to the rod area. Always apply a safety factor for real-world dynamic loads.
Yes, for a 1020 mm stroke, the 25 mm rod is susceptible to bending under side loads. It is strongly recommended to use an external linear guide or rod support to prevent premature seal wear and rod buckling, ensuring reliable operation and long service life.
