About the Airtac SC80 Standard Cylinder SC80X520
The AirTAC SC80X520 double-acting pneumatic cylinder delivers a substantial 2513 N of push force at 0.5 MPa, stepping up to 4523 N at the maximum operating pressure of 0.9 MPa. This model features a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end, effectively decelerating high-speed loads to reduce end-of-stroke impact.
With a 520 mm stroke and a compact body length A of 182 mm, this genuine AirTAC cylinder is built on a durable tie-rod design. The PT3/8 pneumatic ports ensure solid airflow for consistent cycling in demanding industrial automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X520 Is Used
Material Handling Pusher
Provides the 2513 N force at 0.5 MPa needed to divert medium-weight packages or totes off a conveyor line, with the 520 mm stroke covering wide belt sections.
Clamping & Fixturing
Generates up to 4523 N of clamping force at 0.9 MPa for securing large workpieces during machining or welding, where the 520 mm reach is essential for part clearance.
Farm Equipment Actuation
Operates chutes, gates, or levers on agricultural machinery, leveraging the 80 mm bore's force and long stroke for reliable remote actuation in dusty environments.
Is the Airtac SC80 Standard Cylinder SC80X520 the Right Cylinder?
For applications needing more force, the SC100 bore increases push force to 3927 N at 0.5 MPa. If a shorter, more compact unit is acceptable, the SC63 bore provides 1559 N. At a 520 mm stroke, ensure the 25 mm rod is adequately supported against side loads; for off-center or guided loads, consider pairing this cylinder with an external linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear. To replace an existing unit, match the 80 mm bore, 520 mm stroke, PT3/8 port thread, basic mounting, and confirm if a magnet is needed.
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 SC80X520 FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N.
No. A 520 mm stroke with a 25 mm rod is susceptible to bending under side loads. An external guide rail or a rod-alignment coupler is strongly recommended to protect the rod, bearings, and seals from premature failure.
