About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300SH
The AirTAC SC125X1300SH 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 a 1300 mm stroke and a 32 mm diameter piston rod, this model is built for long linear movements in demanding thermal environments.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0 to +150 °C. The adjustable pneumatic cushion at each end is 28 mm long, softening end-of-stroke impact for the 125 mm bore tie-rod body.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300SH Is Used
High-Temperature Process Automation
The Viton seals enable reliable operation in ovens, autoclaves, and foundry equipment up to 150°C, where standard seals would degrade.
Long-Stroke Material Handling
With 1300 mm of travel and 11045 N of force, this cylinder is ideal for pushing heavy pallets or transferring large components between conveyor lines.
Sensor-Controlled Clamping
The built-in magnet allows end-of-stroke sensors to confirm full clamp or release positions, providing closed-loop feedback for automated assembly fixtures.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300SH the Right Cylinder?
For applications needing more force, step up to the 160 mm bore SC160 series, which provides 10053 N at 0.5 MPa. For a lighter, more compact solution, the SC100 bore offers 3927 N at the same pressure. At a 1300 mm stroke, the rod is fully supported within the cylinder, but any external side loading must be managed with an external guide system to prevent rod bearing damage and bending.
To ensure a correct drop-in replacement, match five key points: bore (125 mm), stroke (1300 mm), PT port thread, the built-in magnet (-S), and the Viton seal material. This model is a standard stroke, non-ISO 15552 tie-rod cylinder, dimensionally interchangeable only with another AirTAC SC125 of the same configuration.
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 SC125X1300SH 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.
No. As a standard double-acting cylinder, the SC125X1300SH will drift or drop if pressure is exhausted. The adjustable air cushion only decelerates the piston at the end of stroke; it does not lock the position. For load holding without pressure, you must add an external rod brake or a pilot-operated check valve.
