About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200SH
The AirTAC SC160X1200SH is a double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter piston rod and 1200 mm stroke make it a powerful linear drive for heavy-duty industrial tasks requiring a long reach.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C for high-heat environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200SH Is Used
Sawmill & Timber Processing
Drives log positioning arms and carriage feeds with 18095 N of force at 0.9 MPa. Viton seals withstand the high ambient heat from drying kilns and engine compartments.
Heavy-Duty Material Handling
Powers large bin gates and chute diverters in mining and aggregate. The 1200 mm stroke provides the necessary travel for wide openings, while the magnet allows sensor feedback for automated sequencing.
Hot Press & Molding Machinery
Applies sustained clamping pressure in composite molding or rubber vulcanization presses. The 0–150 °C seal rating ensures reliability in direct contact with heated platens.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200SH the Right Cylinder?
For applications needing slightly less force, the 125 mm bore SC series provides 6136 N at 0.5 MPa. If a longer stroke is required, the SC160 bore supports standard strokes up to 1500 mm. At a 1200 mm stroke, the rod is fully supported by the guide bushing at the head, but external side loads must be managed with an external guide or linear rail system to prevent rod bending and premature seal wear.
To ensure a correct replacement, match five key points: bore (160 mm), stroke (1200 mm), port thread (PT3/4), mounting style (basic, no bracket), and the magnet option (-S). This model also requires Viton seals for high-temperature compatibility.
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 SC160X1200SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall body length than a comparable ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It will only directly replace another AirTAC SC tie-rod cylinder with the same 160 mm bore, 1200 mm stroke, PT3/8 port, and -S magnet option.
