About the Airtac SC80 Standard Cylinder SC80X500
The SC80X500 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 500 mm stroke. At 0.5 MPa it generates 2513 N of push force, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust mid-range actuator for general industrial automation.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. Its body length A is 182 mm, giving a total extended length of approximately 682 mm. The adjustable pneumatic cushion at each end (28 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact without any mechanical locking function.

Where the Airtac SC80 Standard Cylinder SC80X500 Is Used
Package Sorting Gate
The 500 mm stroke and 2513 N force at 0.5 MPa effectively divert medium-weight parcels on conveyor lines, with adjustable cushioning to soften the gate action.
Material Clamping Fixture
Delivers a controlled 4523 N clamping force at 0.9 MPa for holding workpieces during machining or welding, where the tie-rod construction offers serviceability.
Pallet Layer Positioning
Moves a pallet layer by 500 mm in a stacking system. The 25 mm rod is rigid enough for axial pushing, provided the load is guided on rails to prevent side deflection.
Is the Airtac SC80 Standard Cylinder SC80X500 the Right Cylinder?
Choose the SC80X500 when the SC63 series (1559 N at 0.5 MPa) is force-limited for your application; if you need more power, the SC100 bore delivers 3927 N at the same pressure. For this 500 mm stroke, ensure the rod is not subjected to significant side loading—long, unsupported rods can bend under lateral force. Use an external linear guide or switch to a guided cylinder if side loads are present.
When replacing an existing cylinder, match five points exactly: 80 mm bore, 500 mm stroke, PT3/8 port thread, basic mounting (no accessory brackets), and the absence of a built-in magnet. This SC model is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X500 FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf (approx. 5030 N push).
No. The SC80X500 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a position without live pressure, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
