About the Airtac SC80 Standard Cylinder SC80X350SH
The SC80X350SH 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 and a 350 mm stroke, this model features a 25 mm diameter piston rod and a 28 mm adjustable air cushion, making it a robust workhorse for medium-to-heavy linear motion tasks.
This variant is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and high-temperature Viton (FKM) seals (-H), extending the operating range from 0 to +150 °C. The standard PT1/8 port and tie-rod construction ensure reliable service in hot environments where standard seals would degrade.

Where the Airtac SC80 Standard Cylinder SC80X350SH Is Used
Foundry & Heat Treatment
The Viton seals withstand ambient temperatures up to 150°C, making this cylinder ideal for actuating dampers, clamps, and pushers near furnaces, ovens, or autoclaves where standard seals would fail.
High-Temp Material Handling
With 4523 N of force at 0.9 MPa and sensor feedback from the built-in magnet, this cylinder reliably pushes hot parts or rejects off a conveyor in glass, ceramics, or baking production lines.
Hot Press & Molding
Delivers consistent, strong clamping force for hot press cycles. The adjustable cushion decelerates the 350 mm stroke smoothly, protecting the mold and reducing cycle shock in elevated temperature environments.
Is the Airtac SC80 Standard Cylinder SC80X350SH the Right Cylinder?
For applications requiring higher force, consider stepping up to the SC100 series, which provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the SC63 delivers 1559 N at the same pressure. For this 350 mm stroke, ensure the load is guided externally to prevent excessive side-load bending on the 25 mm rod, which can damage the rod bearing and seals.
When replacing an existing cylinder, match five key points: the 80 mm bore, 350 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 tie-rod units.
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 SC80X350SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N. At the maximum operating pressure of 0.9 MPa, it reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. As a standard double-acting cylinder, the SC80X350SH will drift or drop if pressure is exhausted or the directional valve is centered. It does not have a mechanical lock. For load holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
