About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400S
The AirTAC SC160X400S is a double-acting tie-rod cylinder delivering a powerful push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 160 mm bore and 400 mm stroke, it is built for heavy-duty industrial tasks requiring substantial force over a moderate distance.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The 40 mm diameter piston rod and 29 mm adjustable air cushion at each end ensure robust performance and smooth deceleration of heavy loads. It uses standard PT ports (PT3/4) and TPU seals for operation in ambient temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400S Is Used
Heavy Press & Clamping
Delivers up to 18095 N of force at 0.9 MPa, ideal for powerful clamping fixtures, stamping presses, and static material compression in manufacturing cells.
Pallet & Product Pushers
The 400 mm stroke and high force capacity efficiently transfer heavy pallets, engine blocks, or large assemblies between conveyor lines and machining centers.
Damper & Gate Actuation
Used to operate heavy dampers, hopper gates, or diverter chutes in bulk material handling, where the robust 40 mm rod withstands harsh, dusty environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400S the Right Cylinder?
Select the SC160X400S when your application demands a force class of roughly 10000 N at standard factory air pressure. For a step down in force and physical size, the SC125 series offers 6136 N of push force at 0.5 MPa. If a longer stroke is needed, the SC160 bore supports standard strokes up to 1500 mm. For strokes over 300 mm, always assess side-loading: a 400 mm stroke with a 40 mm rod may require external guides or a guided cylinder to prevent rod bending under non-axial loads. To replace an existing unit, match these five points: 160 mm bore, 400 mm stroke, PT3/4 port thread, the built-in magnet for sensors, and the basic (no bracket) mounting configuration.
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 SC160X400S FAQ
At 0.5 MPa (5 bar), it provides 10053 N pushing and 9425 N pulling. At 0.7 MPa, the push force increases to 14074 N, and at the maximum operating pressure of 0.9 MPa, it reaches 18095 N.
Yes. The -S suffix indicates a built-in magnetic piston ring. You can clamp compatible AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors directly onto the tie-rod barrel for contactless position sensing without additional brackets.
