About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250S
The SC160X250S is a double-acting pneumatic cylinder delivering substantial linear force for heavy-duty automation. With a 160 mm bore and 250 mm stroke, it generates 10053 N pushing force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a 40 mm diameter piston rod.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for contactless position feedback. The adjustable air cushion (29 mm length) decelerates the piston smoothly at stroke ends, protecting the end caps during high-cycle operation. As a genuine AirTAC SC series cylinder, it uses PT1/4 ports and operates reliably on filtered air from -20 to +70 °C with standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250S Is Used
Heavy Press & Clamping
The 18095 N push force at 0.9 MPa makes the SC160 ideal for hydraulic-press alternatives, heavy-duty clamping fixtures, and riveting stations where consistent, controlled force is critical.
Palletising & Material Handling
Use the SC160X250S for pallet lifters, heavy box pushers, and transfer stations. The built-in magnet provides end-of-stroke confirmation to the PLC, ensuring reliable automated sequencing.
Industrial Gate & Damper Actuation
Deploy this cylinder for large hopper gates, diverter chutes, or ventilation dampers. The adjustable cushion absorbs the kinetic energy of the heavy gate, reducing noise and mechanical shock.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250S the Right Cylinder?
Select the SC160 bore when your application requires between 9425 N (pull at 0.5 MPa) and 18095 N (push at 0.9 MPa). For lower force requirements, step down to the SC125 bore, which provides 6136 N push at 0.5 MPa. For even higher force, the SC200 bore delivers 15708 N push at 0.5 MPa. At a 250 mm stroke, side loading on the 40 mm rod is manageable for most inline applications, but for off-axis loads, consider an external guide or a guided cylinder to prevent rod bearing wear. For direct replacement, match bore, stroke, PT port thread, basic mounting, and the -S magnet option to ensure sensor compatibility with your existing setup.
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 SC160X250S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides a push force of 10053 N and a pull force of 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.
Yes. The -S suffix in the model code SC160X250S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
