About the Airtac SC80 Standard Cylinder SC80X280LB
The SC80X280LB is an 80 mm bore, 280 mm stroke double-acting pneumatic cylinder delivering 2513 N of push force 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 provide smooth deceleration for mid-to-heavy linear motion tasks.
This model includes the LB axial foot mount (F-SC80LB) for secure surface installation. The cylinder body length A is 182 mm, giving a total extended length of approximately 462 mm. Standard PT ports (PT3/8) and TPU seals rated for -20 to +70 °C complete the build.

Where the Airtac SC80 Standard Cylinder SC80X280LB Is Used
Conveyor Diverter Gates
Provides the 2513 N push force needed to reliably actuate diverter gates and sorting paddles on medium-duty package handling lines, with the LB foot mount ensuring rigid alignment.
Press-Fit Assembly Stations
Delivers up to 4523 N at 0.9 MPa for controlled press-fit insertion of bearings or bushings. The adjustable cushion protects tooling from impact damage at the end of the 280 mm stroke.
Pallet Stop & Lift Mechanisms
The 280 mm stroke and high force capacity make it suitable for lifting or stopping heavy pallets in automated storage and retrieval systems, where the foot mount provides a stable base.
Is the Airtac SC80 Standard Cylinder SC80X280LB the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 series offers 1559 N at the same pressure. Always match replacement cylinders on all five key points: 80 mm bore, 280 mm stroke, PT port thread, LB foot mount, and the absence of a magnet.
At 280 mm stroke, the 25 mm rod is well-supported within standard limits, but any significant side load or off-axis force requires an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear.
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 SC80X280LB FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes, if your old cylinder is an AirTAC SC series tie-rod type with an 80 mm bore, 280 mm stroke, PT ports, and an LB foot mount. This is not an ISO 15552 cylinder; it is a tie-rod design and will only directly interchange with another AirTAC SC cylinder of the same exact configuration.
