About the Airtac SC80 Standard Cylinder SC80X70SH
The SC80X70SH is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, ideal for medium-duty clamping and pressing tasks. Its 70 mm stroke combined with a 25 mm diameter piston rod provides a compact yet robust actuation solution.
This model features a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and Viton (FKM) seals, extending the operating temperature range to 0–150 °C. The adjustable air cushion at each end decelerates the 80 mm bore piston smoothly over a 28 mm cushion length.

Where the Airtac SC80 Standard Cylinder SC80X70SH Is Used
High-Temperature Automation
With Viton seals rated for 0–150 °C, this cylinder is suited for foundry equipment, autoclaves, and hot stamping presses where standard seals would degrade.
Sensor-Controlled Actuation
The built-in magnet allows CMSG/DMSG/EMSG solid-state or reed sensors to clamp directly onto the tie-rod barrel for precise end-of-stroke position feedback.
Medium-Force Clamping
Generating 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, it handles heavy-duty clamping, riveting, and punching operations with ease.
Is the Airtac SC80 Standard Cylinder SC80X70SH the Right Cylinder?
For higher force requirements, stepping up to the 100 mm bore provides 3927 N of push force at the same 0.5 MPa pressure. The 25 mm rod on this 80 mm bore offers good column strength, but for strokes beyond 300 mm with any side load, an external guide rail is recommended to protect the rod bearing from bending moments. When replacing an existing cylinder, ensure a match on bore, stroke, PT port thread, the -S magnet option, and the high-temperature Viton seal material.
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 SC80X70SH FAQ
At 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.
No, the AirTAC SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profiles. It is not dimensionally interchangeable. Use AirTAC SC-specific mounting accessories like FA, FB, CA, CB, or TC trunnions.
