About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400SH
The SC125X1400SH is a large-bore, single-rod double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the 0.9 MPa maximum operating pressure. With a 32 mm piston rod and a 28 mm adjustable air cushion, it is built for heavy industrial linear tasks where high force and a long 1400 mm stroke are essential.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C. The PT1/2 port and M27x2 rod thread provide robust fluid and mechanical connections for demanding environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400SH Is Used
High-Temperature Kiln & Dryer Actuation
The Viton seals enable reliable operation in ambient temperatures up to 150°C, making this cylinder ideal for actuating dampers, gates, or pushers in lumber drying kilns, industrial ovens, and heat-treatment lines.
Heavy-Duty Clamping & Pressing
Generating over 11000 N of force at 0.9 MPa, the SC125X1400SH excels in hydraulic-replacement clamping fixtures, large-part pressing, and heavy assembly jigs where high force and a long stroke are needed.
Foundry & Hot-Material Handling
With its 0-150°C temperature range and robust tie-rod construction, this cylinder is suited for diverting or stopping heavy, hot materials on foundry conveyors and steel mill roller tables.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400SH the Right Cylinder?
Select the SC125 bore when your application requires a push force between 6136 N (at 0.5 MPa) and 11045 N (at 0.9 MPa). If your force requirement is lower, stepping down to the SC100 bore offers 3927 N at 0.5 MPa. For a 1400 mm stroke, always evaluate side-loading on the 32 mm rod; an external guide or guided cylinder is strongly recommended to prevent rod bending and premature bearing wear.
To ensure a correct drop-in replacement, match five key points: 125 mm bore, 1400 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation.
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 SC125X1400SH 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 reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder and is not dimensionally interchangeable. It is an ISO 6430 class cylinder. It will only directly replace another AirTAC SC tie-rod cylinder with the same bore, stroke, PT port, magnet option, and Viton seals.
