About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450SH
The AirTAC SC160X450SH is a double-acting tie-rod cylinder with a 160 mm bore and 450 mm stroke, factory-equipped with a built-in magnet (-S suffix) and high-temperature Viton (FKM) seals (-H suffix). It generates 10053 N of push 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 with M36x2 male threads.
This model's Viton seals shift the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade. The adjustable pneumatic cushion (29 mm length) decelerates the piston near stroke end to reduce impact, and the built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for non-contact position sensing. Ports are PT3/4, and the body length A is 239 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450SH Is Used
Hot-Environment Pressing
Viton seals rated to 150 °C allow this cylinder to operate in heated platen presses, autoclave door actuators, and foundry equipment where ambient temperatures exceed standard seal limits.
Heavy Pallet Lifting
With 10053 N push at 0.5 MPa, the SC160X450SH raises loaded pallets in high-bay warehouse lifts. The 450 mm stroke provides ample vertical travel for single-level elevation stations.
Sensor-Monitored Clamping
The built-in magnet enables CMSG/DMSG sensors to confirm full extension and retraction, critical for automated welding fixtures and CNC clamp/unclamp sequences where position verification is mandatory.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450SH the Right Cylinder?
Choose the SC160 bore when your application needs roughly 10000 N of force at standard plant air pressure (0.5 MPa). If the load is lighter, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For heavier loads beyond this cylinder's 0.9 MPa thrust, move up to the SC200 (28274 N push at 0.9 MPa).
At 450 mm stroke, the 40 mm rod is robust, but any significant side load still demands an external guide or a guided cylinder to protect the rod bearing from bending stress. For direct replacement, match these five points exactly: 160 mm bore, 450 mm stroke, PT3/4 port thread, the built-in magnet (-S), and the Viton seal (-H). This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC160 of the same 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 SC160X450SH FAQ
At 0.7 MPa (7 bar) supply pressure, this 160 mm bore cylinder delivers 14074 N of push force and 9425 N of pull force on the retract stroke, based on the official AirTAC thrust table.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 profile cylinders. Use it to replace another AirTAC SC160 tie-rod cylinder with matching bore, stroke, PT ports, magnet, and Viton seals.
