About the Airtac SC80 Standard Cylinder SC80X1260
The SC80X1260 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 1260 mm stroke. At 0.5 MPa it generates 2513 N of push force and 2268 N on the pull stroke, driven by a 25 mm diameter piston rod with an M20x1.5 male thread.
This model includes PT3/8 ports and an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly. The body length A is 182 mm, giving a total extended length of approximately 1442 mm. Standard TPU seals provide an operating range of -20 to +70 °C, and the cylinder is rated for a maximum operating pressure of 1.0 MPa.

Where the Airtac SC80 Standard Cylinder SC80X1260 Is Used
Long-Reach Material Transfer
The 1260 mm stroke suits extended linear pushers or pullers on packaging lines, moving products across wide conveyor gaps with controlled 2513 N force at standard line pressure.
Automated Panel Indexing
Positions large sheet-metal or wood panels through multi-station processing. The adjustable cushion protects the 25 mm rod and end caps during high-cycle indexing at speeds up to 800 mm/s.
Gantry-Style Pick-and-Place
Provides the horizontal axis for a light gantry. The tie-rod construction allows straightforward mounting of external guides to manage the long stroke's side-load moment.
Is the Airtac SC80 Standard Cylinder SC80X1260 the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 delivers 1559 N at the same pressure. Always match replacement cylinders across five key points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
At 1260 mm, this stroke is long relative to the rod diameter. Unsupported side loads can cause rod bending or premature bearing wear. For this configuration, an external guide rail or a guided cylinder assembly is strongly recommended to absorb transverse forces and protect the rod bearings.
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 SC80X1260 FAQ
At 0.5 MPa air 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 reaches 4523 N.
It is not recommended. A 1260 mm stroke with a 25 mm rod creates a significant moment arm. Applying any side load without an external guide rail will bend the rod and damage the piston bearing. An external guide or a self-guided cylinder is required for reliable operation.
