About the Airtac SC80 Standard Cylinder SC80X680SH
The SC80X680SH is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore, 25 mm diameter piston rod, and a 680 mm stroke, this model is built for medium-to-heavy linear tasks requiring a long reach.
This variant includes a built-in magnet (-S) for mounting CMSG, DMSG, or EMSG sensors directly on the tie-rod barrel, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C. The total extended body length is approximately 862 mm, and the adjustable air cushion (28 mm) at both ends ensures smooth deceleration.

Where the Airtac SC80 Standard Cylinder SC80X680SH Is Used
High-Temperature Material Handling
With Viton seals rated to 150°C, this cylinder reliably operates gates and diverters on conveyor lines near ovens, dryers, or autoclaves where standard seals would degrade.
Long-Stroke Clamping & Fixturing
The 680 mm stroke and 4523 N of force at 0.9 MPa make it suitable for clamping large automotive or furniture components during assembly, with sensor feedback confirming open/closed positions.
Vertical Lift Assist in Hot Zones
Deploy this cylinder in a vertical lift-assist station exposed to process heat. The magnetic piston allows end-of-stroke sensing to sequence with other automation safely.
Is the Airtac SC80 Standard Cylinder SC80X680SH the Right Cylinder?
Choose the SC80 when your application needs between 628 N (SC40) and 1559 N (SC63) of force at 0.5 MPa—this bore steps up to 2513 N. For strokes of 680 mm, side-load management is critical: the 25 mm rod can experience bending under off-axis forces, so use an external guide or a guided cylinder for long-stroke push/pull setups.
For a direct replacement, match five points: 80 mm bore, 680 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC80X680SH FAQ
At 0.7 MPa operating pressure, the SC80 bore generates 3518 N of push force. The pull force on the retract stroke is 2268 N at 0.5 MPa, accounting for the 25 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It will only directly replace another AirTAC SC80 tie-rod cylinder with matching bore, stroke, PT ports, magnet option, and basic mounting.
