About the Airtac SC80 Standard Cylinder SC80X75N
The AirTAC SC80X75N is an 80 mm bore, 75 mm stroke double-acting tie-rod cylinder fitted with NBR (nitrile) seals. At 0.5 MPa it generates 2513 N pushing force and 2268 N on the pull stroke, making it a capable mid-range actuator for general industrial tasks. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the PT3/8 port supplies ample flow for speeds up to 800 mm/s.
This NBR-sealed variant suits environments where oil mist is present or where nitrile's abrasion resistance is preferred. The body length A is 182 mm, giving a total extended length of approximately 257 mm. As a genuine AirTAC SC series cylinder, it offers a compact tie-rod design that is shorter than an equivalent ISO 15552 profile, saving space on the machine frame.

Where the Airtac SC80 Standard Cylinder SC80X75N Is Used
Package Diverting
Pushes cartons off a conveyor line with 2513 N of force at 0.5 MPa. The 75 mm stroke provides a clean, fast divert action in packaging machinery.
Clamping Fixtures
Applies consistent clamping pressure to workpieces during machining or welding. The NBR seals tolerate oily shop air, and the 28 mm cushion softens clamp contact.
Press-Fit Assembly
Delivers up to 4523 N at 0.9 MPa for pressing bearings or bushings into housings. The tie-rod construction handles repetitive impact loads reliably.
Is the Airtac SC80 Standard Cylinder SC80X75N the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2513 N and 4523 N of thrust at standard plant air pressures (0.5–0.9 MPa). If your load requires less force, stepping down to the SC63 bore saves space and air consumption—the SC63 delivers 1559 N push at 0.5 MPa. For higher force, the SC100 bore provides 3927 N at the same pressure.
When replacing an existing cylinder, match five points: 80 mm bore, 75 mm stroke, PT3/8 port thread, NBR seal material, and the basic (no bracket) mounting configuration. If you later need magnetic piston sensing, order the SC80X75N-S variant to accept CMSG/DMSG sensors. For strokes above 300 mm in this bore, consider an external guide or a guided cylinder to protect the 25 mm rod from side-load bending.
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 SC80X75N FAQ
At 0.7 MPa operating pressure, the SC80 bore generates 3518 N of force on the push stroke and 3175 N on the pull stroke (theoretical values). For maximum force, at 0.9 MPa it reaches 4523 N push.
No. The 'N' suffix denotes NBR (nitrile) seals, rated for standard temperatures. If you need high-temperature operation up to 150 °C, order the SC80X75H variant with Viton (FKM) seals instead.
