About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800SH
The AirTAC SC125X800SH is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With an 800 mm stroke and a robust 32 mm piston rod, this model is built for heavy linear work in high-temperature environments.
This variant is equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and Viton (FKM) seals (-H), shifting the operating temperature range to 0 to +150 °C. The adjustable air cushion (28 mm length) decelerates the piston smoothly at both ends, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800SH Is Used
High-Temperature Foundry Actuation
Viton seals allow reliable operation in ambient temperatures up to 150°C, making this cylinder ideal for clamping, ejecting, or positioning near furnaces and die-casting machines.
Heavy-Duty Press & Forming
With a maximum theoretical force of 1251 kgf, the SC125X800SH provides the muscle for medium-tonnage pressing, bending, and riveting operations requiring a long working stroke.
Automated Pallet Transfer
The 800 mm stroke combined with sensor-ready magnet rings enables precise end-of-stroke detection for long-distance pallet pushing or product transfer in automated lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800SH the Right Cylinder?
For applications needing more force, consider stepping up to the SC160 bore (10053 N push at 0.5 MPa). If a lower force is sufficient, the SC100 bore provides 3927 N at 0.5 MPa. This 800 mm stroke places significant bending stress on the rod under side loads; an external guide or a guided cylinder is strongly recommended to prevent rod bearing damage and ensure linear motion stability.
When replacing an existing cylinder, match five key points: 125 mm bore, 800 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 another AirTAC SC125 or an equivalent tie-rod design.
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 AIRTAC SC125-160 Standard Cylinder SC125X800SH FAQ
At 0.7 MPa (7 bar) operating pressure, the push force is 8590 N. The maximum push force at 0.9 MPa is 11045 N. The theoretical force at 1.0 MPa is 1251 kgf, but the cylinder is rated for a maximum operating pressure of 1.0 MPa.
No. The SC125X800SH 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 stroke to reduce impact; it is not a locking or braking device. For load holding, you must add an external rod lock or a pilot-operated check valve.
