About the Airtac SC80 Standard Cylinder SC80X920
The AirTAC SC80X920 is an 80 mm bore double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 25 mm diameter piston rod and 28 mm adjustable air cushion are sized for medium-to-heavy linear tasks where a long 920 mm working stroke is required.
With a compact body length A of just 182 mm, the cylinder extends to a total length of approximately 1102 mm. The standard PT3/8 ports and M20x1.5 rod thread make fluid connections and tooling attachment straightforward. This model uses the default TPU seals for a -20 to +70 °C operating range.

Where the Airtac SC80 Standard Cylinder SC80X920 Is Used
Long-Reach Part Transfer
Moves heavy components 920 mm across conveyor lines or between machining stations, using its 2513 N push force at 0.5 MPa to shift pallets or fixtures reliably.
Automated Clamping & Riveting
Provides the 4523 N maximum thrust at 0.9 MPa for pressing, clinching, or clamping large weldments on an automated assembly frame, with cushioning to soften end-of-stroke impact.
Hopper Gate Actuation
Opens and closes discharge gates on bulk material hoppers. The 25 mm rod and tie-rod construction handle dusty environments when air is properly filtered to 40 µm.
Is the Airtac SC80 Standard Cylinder SC80X920 the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If your load exceeds 2500 N, consider stepping up to the 100 mm bore SC100 which offers 3927 N at the same pressure. To ensure a direct replacement, match five points: 80 mm bore, 920 mm stroke, PT3/8 port thread, the basic (no bracket) mounting style, and the absence of a built-in magnet.
At a 920 mm stroke, the piston rod is fully extended well beyond the body, making it susceptible to bending under side loads. Never subject this cylinder to lateral forces without an external guide rail or rod support; doing so will damage the rod bearing and seals. For guided motion, pair it with an external linear guide system.
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 SC80X920 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. At a 920 mm stroke, the 25 mm diameter rod is highly vulnerable to bending and buckling if subjected to any side load. You must install an external guide rail or rod support to constrain the load and protect the rod bearing, or the cylinder will suffer premature seal and bearing failure.
