About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X240S
The SC160X240S is a robust double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to a substantial 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 240 mm stroke, this model is built for heavy linear actuation tasks, featuring an adjustable pneumatic cushion (29 mm length) to decelerate high-inertia loads smoothly at the end of travel.
This configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable, non-contact position feedback. The standard PT (Rc) port threads and TPU seals provide a dependable operating range of -20 to +70 °C, making it a versatile workhorse for demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X240S Is Used
Heavy Press-Fit Assembly
Generates up to 18095 N of force at 0.9 MPa, ideal for installing bearings, bushings, or pins with high precision and repeatability in automated assembly cells.
Pallet Stop & Lift Gate
Provides the high holding and lifting force needed for heavy pallet stops or lift-and-transfer gates in conveyor systems, with sensors confirming gate position for safety interlocks.
Molding Machine Ejection
Delivers the powerful, controlled thrust required for ejecting large plastic or rubber parts from molds, with adjustable cushioning to protect the mold and part surface finish.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X240S the Right Cylinder?
Select the SC160 when your application requires a force class around 10053 N at 0.5 MPa. If you need a more compact solution with lower force, stepping down to the SC125 bore offers 6136 N of push force at the same pressure. For strokes of 240 mm, ensure that any side loads are managed; the 40 mm rod is robust, but for off-center loads, an external guide or a guided cylinder is recommended to prevent rod bearing wear and ensure long service life.
For a direct replacement, match these five key specifications: a 160 mm bore, a 240 mm stroke, PT port threads, a basic (footless) mounting configuration, and the built-in magnet for sensor compatibility. This cylinder 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 SC160X240S FAQ
At the maximum operating pressure of 1.0 MPa, the theoretical push force is 2050 kgf (approximately 20100 N). The practical push force at the standard 0.7 MPa supply pressure is 14074 N, and at 0.5 MPa it is 10053 N.
Yes. The -S suffix in the model code SC160X240S signifies a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
