About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900S
The AirTAC SC160X900S is a double-acting tie-rod cylinder delivering substantial linear force, rated at 10053 N push and 9425 N pull at 0.5 MPa. With a 900 mm stroke and a robust 40 mm diameter piston rod, this cylinder is built for demanding industrial tasks requiring long travel and high thrust. The built-in magnet (denoted by the 'S' suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise, non-contact position feedback.
This model features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact noise and extending service life. The body length A is 239 mm, giving a total extended length of approximately 1139 mm. Operating on filtered air from 0.15 to 1.0 MPa, it uses PT1/2 port threads and an M36x2 rod thread. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N, providing a significant power reserve for pressing, clamping, and lifting operations.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900S Is Used
Sawmill & Timber Processing
Provides the high force and long stroke needed for log positioning, carriage drives, and pressing operations in dusty, demanding sawmill environments. The magnetic piston enables end-of-stroke sensing for automated feed systems.
Heavy Press-Fit Assembly
Delivers up to 18095 N of push force at 0.9 MPa for installing large bearings, bushings, or gears. The 900 mm stroke accommodates deep workpieces, while the adjustable cushioning ensures a controlled, low-impact press cycle.
Palletizer & Conveyor Divert
Ideal for high-speed palletizing layer-push or heavy-duty diverter gates. The built-in magnet allows precise position confirmation via CMSG/DMSG sensors, ensuring reliable integration into automated packaging lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900S the Right Cylinder?
When sizing, compare the SC160's 10053 N push force at 0.5 MPa with the SC125 (6136 N) and SC200 (15708 N). If your load is below 6000 N, stepping down to a 125 mm bore may reduce air consumption; for loads approaching 15000 N, the 200 mm bore is a better match. For this 900 mm stroke, side-load management is critical—the 40 mm rod is strong, but an unsupported long stroke can experience bending under off-axis loads. Always use an external guide rail or rod-alignment coupler to protect the rod bearing and seals.
To ensure a drop-in replacement, match five key points: 160 mm bore, 900 mm stroke, PT1/2 port thread, the basic mounting style (no integrated bracket), and the built-in magnet (-S suffix) for sensor compatibility. This SC cylinder is a tie-rod design and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not interchangeable with those types. For big-bore applications, it conforms to the ISO 6430 class standard.
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 SC160X900S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 14074 N, and the pull force is 13195 N (calculated from the 9425 N pull force at 0.5 MPa). The maximum push force at 0.9 MPa is 18095 N. Always apply a safety factor for real-world dynamic loads.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder. Mounting accessories are specific to the SC series, using part codes like F-SC160LB for a foot mount. For this model with basic mounting, you would order the required bracket separately if needed.
