About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800STC
The SC160X800STC is a 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). With an 800 mm stroke and a 40 mm diameter piston rod, this model suits heavy linear actuation tasks where substantial force and moderate reach are required.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with the TC centre trunnion mounting (F-SC160TC) plus the TCM1 bracket for pivoting applications. The body length A is 239 mm, giving a total extended length of approximately 1039 mm. Ports are PT3/4, and the adjustable pneumatic cushion (29 mm) decelerates the piston smoothly at end of stroke.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800STC Is Used
Heavy Press & Clamping
Generates up to 18095 N of force at 0.9 MPa, ideal for hydraulic-free pressing, clamping fixtures, and heavy assembly jigs where consistent pneumatic power is needed.
Pivoting Conveyor Gates
The TC centre trunnion mount allows the cylinder to swing as it actuates, perfect for diverters, gates, and chutes on material handling lines handling pallets or bulk goods.
Large Part Ejection
With an 800 mm stroke and robust 40 mm rod, this cylinder can push large formed parts or heavy moulded components off a production line with reliable, repeatable motion.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800STC the Right Cylinder?
For applications needing slightly less force, the SC125 bore provides 6136 N push at 0.5 MPa, while stepping up to the SC200 bore offers 15708 N. The 800 mm stroke on a 40 mm rod requires careful alignment; any significant side load can cause rod bending or bearing wear. For non-linear or guided motion, consider pairing this cylinder with an external linear guide.
When replacing an existing cylinder, match five key points: 160 mm bore, 800 mm stroke, PT3/4 port thread, TC centre trunnion mounting (with TCM1 bracket), and the built-in magnet (-S) for sensor compatibility. This ensures a direct dimensional and functional swap with another AirTAC SC series unit.

- ✓ 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 SC160X800STC FAQ
At 0.5 MPa (approximately 5 bar), the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in the model code 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 end-of-stroke or intermediate positions.
