About the Airtac SC80 Standard Cylinder SC80X820SN
The AirTAC SC80X820SN is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a powerful actuator for medium-to-heavy linear motion tasks. With an 80 mm bore, 25 mm piston rod, and a 28 mm adjustable air cushion, this model handles an 820 mm stroke while the tie-rod construction keeps the total extended length compact at approximately 1002 mm.
This specific configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position sensing without external brackets. The NBR (-N suffix) seals provide reliable performance with filtered air, and the standard PT1/8 port threads ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X820SN Is Used
Material Handling & Sorting
The 820 mm stroke and 2513 N push force effectively operate long-reach pushers, diverters, and transfer stations on packaging and assembly lines, especially where sensor feedback from the built-in magnet confirms part position.
Clamping & Fixturing
Delivers consistent, high-force clamping for large workpieces in CNC machining or welding fixtures. The NBR seals and adjustable cushioning provide reliable, controlled motion in demanding shop-floor environments.
Farm & Heavy Equipment Actuation
Suitable for actuating chutes, gates, or levers on agricultural machinery. The robust tie-rod design and NBR seals withstand dusty conditions, while the long 820 mm stroke provides the necessary reach for large mechanisms.
Is the Airtac SC80 Standard Cylinder SC80X820SN the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If your load demands more power, the 100 mm bore SC100 series offers 3927 N at the same pressure. Always ensure the 25 mm rod is adequately supported for this 820 mm stroke; significant side loads can cause rod bending or bearing wear, so an external guide or a guided cylinder is strongly recommended for non-axial loads.
When replacing an existing cylinder, match these five points exactly: 80 mm bore, 820 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the NBR seal material. The SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile, so it is not a drop-in replacement for ISO 15552 cylinders.
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 SC80X820SN FAQ
At the standard operating pressure of 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X820SN is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is exhausted or lost, the piston rod can drift or drop. For load-holding applications, you must use an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
