About the Airtac SC80 Standard Cylinder SC80X615
The SC80X615 is an 80 mm bore, 615 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, rising to 4523 N push at the 0.9 MPa maximum operating pressure. The 25 mm diameter piston rod and 28 mm adjustable air cushion work together to handle substantial mid-range automation loads.
With a body length A of 182 mm, this cylinder's total extended length reaches approximately 797 mm. The 615 mm stroke exceeds the 1500 mm maximum standard stroke for bore 80, making this a non-standard, made-to-order length. Ports are PT3/8 and the rod thread is M20x1.5. This unit ships with the default TPU seals for a -20 to +70 °C operating range and no built-in magnet.

Where the Airtac SC80 Standard Cylinder SC80X615 Is Used
Long-Reach Part Transfer
The 615 mm stroke moves components between distant conveyor lanes or workstations. The 2513 N push force at 0.5 MPa handles heavy pallet or casting transfers in foundry or assembly lines.
Press-Feed Automation
Feeds blanks or sheets deep into a stamping press or CNC machine. The 28 mm adjustable cushion decelerates the 25 mm rod smoothly at both ends of the long stroke, protecting tooling from impact.
Vertical Lift Gate Actuation
Operates a tall vertical lift gate or hopper door requiring extended linear travel. The double-acting design provides powered retraction, and the 2268 N pull force at 0.5 MPa reliably closes the gate.
Is the Airtac SC80 Standard Cylinder SC80X615 the Right Cylinder?
The SC80X615 suits applications needing over half a metre of travel with a force class around 2.5 kN at standard plant pressure. If your load requires more force, stepping up to the SC100 bore provides 3927 N push at 0.5 MPa; if a more compact body is needed, the SC63 bore delivers 1559 N. At this extended 615 mm stroke, side loading on the 25 mm rod must be managed carefully—use an external linear guide or a guided cylinder variant to prevent rod bending and premature bearing wear.
For replacement, match five key points: 80 mm bore, 615 mm stroke, PT3/8 port thread, basic mounting (no brackets), and no magnet. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard; it is a direct replacement only for another AirTAC SC80 cylinder with identical specifications.
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 SC80X615 FAQ
At 0.5 MPa air pressure, the pushing force is 2513 N and the pulling force is 2268 N. At the maximum operating pressure of 0.9 MPa, the pushing force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
For a 615 mm stroke with a 25 mm rod, external guides are strongly recommended if any side load is present. The rod is designed for axial push/pull forces; unsupported side loading at full extension can cause rod deflection, bending, and accelerated seal wear. Use an external guide rail or a guided cylinder configuration.
