About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200SH
The AirTAC SC125X200SH is a double-acting single-rod tie-rod cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 200 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore, making it a robust choice for medium-travel industrial positioning.
This model features a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, plus Viton (FKM) seals (suffix -H) that shift the operating temperature range to 0–150°C. The 32 mm piston rod, M27x2 rod thread, and PT1/2 port thread provide solid mechanical connection and flow capacity for high-force applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200SH Is Used
Heavy Press & Clamping
With 11045 N of thrust at 0.9 MPa, this cylinder suits heavy-duty clamping fixtures and small forming presses where high force in a compact stroke is essential.
Material Handling Gates
The 200 mm stroke and high force are ideal for actuating diverter gates or stops on heavy-duty conveyor systems, handling bulky pallets or dense materials.
High-Temperature Processing
Viton seals enable reliable operation in autoclaves, sterilizers, or drying ovens up to 150°C, making it suitable for food, pharma, or chemical processing equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200SH the Right Cylinder?
Choose the SC125 bore when your load requires roughly 6136 N at standard plant pressure; stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, while moving up to SC160 raises it to 10053 N. For this 200 mm stroke, side-load risk is moderate, but always align the rod axis with the load path and consider an external guide if off-axis forces are present.
To replace an existing cylinder, match all five points: 125 mm bore, 200 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material. The SC series is a tie-rod design 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 SC125X200SH FAQ
At 0.5 MPa, 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X200SH is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
