About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900SH
The AirTAC SC160X900SH is a double-acting pneumatic cylinder delivering a substantial push force of 10053 N at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and a 29 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly.
Configured with the -S magnet option, a built-in magnetic piston band allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making this cylinder suitable for hot environments like foundries or autoclaves where standard seals would degrade.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900SH Is Used
Heavy-Duty Clamping
High-force clamping of large weldments or castings in machining centers, using the 18095 N thrust at 0.9 MPa to secure workpieces during milling or drilling.
Thermal Process Actuation
Operating press rams or ejector mechanisms inside industrial ovens and autoclaves, where the Viton seals reliably handle sustained ambient temperatures up to 150 °C.
Material Handling Lift
Pushing or lifting heavy pallets and dies in a high-bay warehouse, with the built-in magnet enabling precise end-of-stroke and mid-stroke position feedback to the PLC.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900SH the Right Cylinder?
This 160 mm bore cylinder is a high-force actuator; for applications needing less force, the 125 mm bore SC125 series provides 6136 N at 0.5 MPa, while the 200 mm bore SC200 steps up to 15708 N. For this 900 mm stroke, ensure the rod is not subjected to side loading, as the long extension can create a bending moment on the rod bearing; use an external linear guide or a guided cylinder if lateral forces are present.
When replacing an existing cylinder, match five key points: the 160 mm bore, 900 mm stroke, PT port thread, the built-in magnet for sensors (-S), and the Viton seal material (-H). This tie-rod SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with those standards.
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 SC160X900SH FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical pushing force on the outstroke is 14074 N. The pulling force on the instroke is 9425 N at 0.5 MPa, and scales proportionally with pressure.
No. The SC160X900SH is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. To hold a load safely without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
