About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80SH
The SC125X80SH is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with an 80 mm stroke. It generates a push force of 6136 N at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for medium-duty industrial tasks.
This model features the -S magnet option for direct mounting of CMSG/DMSG/EMSG sensors and the -H suffix specifying Viton (FKM) seals. The Viton material shifts the operating temperature range to 0 to +150 °C, suiting hot environments. The 32 mm diameter piston rod has an M27x2 thread, and the adjustable air cushion at each end is 28 mm long.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80SH Is Used
Hot Press Clamping
The Viton seals withstand 150°C ambient temperatures, making this cylinder ideal for clamping fixtures in heated platen presses or thermoforming machines where standard seals would degrade.
High-Force Sorting Gate
With over 11000 N of push force available at 0.9 MPa, this cylinder can reliably actuate heavy diverter gates on high-throughput conveyor systems, and the built-in magnet enables end-of-stroke sensing.
Material Handling Pusher
The 80 mm stroke and 6136 N force at standard line pressure are well-suited for ejecting or pushing heavy components off a production line, with the tie-rod design allowing for robust, rigid mounting.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80SH the Right Cylinder?
Select the SC125 bore when the 100 mm bore's 3927 N push force at 0.5 MPa is insufficient for the load. If your application requires less force, stepping down to the SC100 bore reduces air consumption and physical size. For strokes of 300 mm or longer, evaluate side-load conditions carefully; a 32 mm rod can experience bending under high side forces, and an external guide or guided cylinder is recommended.
To guarantee a drop-in replacement, match five key points: 125 mm bore, 80 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This 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 AIRTAC SC125-160 Standard Cylinder SC125X80SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC125X80SH is a double-acting cylinder and will not hold its position if air pressure is lost, exhausted, or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke to reduce impact; it is not a locking or holding brake. For load holding without live pressure, an external rod lock or pilot-operated check valve is required.
