About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250SH
The AirTAC SC160X250SH is a robust double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter piston rod and 29 mm adjustable air cushion are built to manage high-inertia loads smoothly through the 250 mm stroke.
This model is equipped with a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors for reliable end-of-stroke detection. The 'H' suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150°C, making it suitable for hot environments like foundries or drying lines.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250SH Is Used
Heavy Press Actuation
Operates high-force forming or stamping presses where heat is a factor, with Viton seals maintaining integrity up to 150°C.
Hot Material Handling
Pushes or diverts heavy, hot materials on conveyor lines in steel mills or glass plants without seal degradation.
Large Clamping Fixtures
Provides 18,095 N of clamping force at 0.9 MPa for welding or assembly jigs in high-temperature manufacturing cells.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250SH the Right Cylinder?
For applications needing slightly less force, the SC125 bore provides 6136 N of push force at 0.5 MPa. If more force is required, the SC200 bore offers 15708 N at the same pressure. When replacing this cylinder, ensure the new unit matches the 160 mm bore, 250 mm stroke, PT3/4 port thread, built-in magnet, and Viton seals. For strokes over 300 mm, consider an external guide to protect the 40 mm rod from side-load bending moments.
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 SC160X250SH FAQ
At the standard 0.5 MPa operating pressure, it generates 10053 N pushing and 9425 N pulling. At the maximum 0.9 MPa, the push force increases to 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It will only directly interchange with another AirTAC SC160 tie-rod cylinder with matching bore, stroke, PT ports, magnet, and Viton seals.
