About the Airtac SC80 Standard Cylinder SC80X550SH
The AirTAC SC80X550SH is a double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at the maximum 0.9 MPa operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide a robust, decelerated end-of-stroke action for the 550 mm stroke length.
This model features the -S magnet option, embedding a magnetic ring on the piston so CMSG/DMSG/EMSG sensors can be mounted directly onto the barrel for contactless position sensing. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot or chemically aggressive environments where standard TPU seals would degrade.

Where the Airtac SC80 Standard Cylinder SC80X550SH Is Used
High-Temperature Automation
The Viton seals allow this SC80X550SH to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, controlling dampers or material handling gates.
Long-Stroke Part Transfer
With 550 mm of travel and 2513 N of push force, it efficiently transfers heavy components between conveyor lines or into assembly fixtures, with magnetic sensors verifying full extension and retraction.
Chemical Process Actuation
The FKM seal material resists aggressive chemical vapors, making this cylinder a reliable choice for actuating valves, diverters, or dosing mechanisms in chemical processing plants.
Is the Airtac SC80 Standard Cylinder SC80X550SH the Right Cylinder?
For applications requiring less force, consider stepping down to the 63 mm bore (1559 N at 0.5 MPa). If a pivoting mount is needed, the TC centre trunnion (F-SC80TC) or CA/CB rear clevis options can be specified in the order code. At 550 mm, the stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore, but the extended rod length warrants caution with side loads—use an external guide or ensure the load is purely axial to prevent rod bending and premature bearing wear.
For a correct replacement, match these five points: 80 mm bore, 550 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (-H). This cylinder is a direct dimensional match only for another AirTAC SC80 tie-rod cylinder with the same 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 SC80X550SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 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 SC80X550SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of the stroke to reduce impact; it is not a locking or holding device. For load holding, you must add an external rod brake or a pilot-operated check valve.
