About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X40S
The SC160X40S is a double-acting single-rod pneumatic cylinder delivering a substantial 10053 N of push force at 0.5 MPa (up to 18095 N at 0.9 MPa). With a 40 mm rod and M36x2 knuckle thread, this 160 mm bore actuator is built for heavy linear work in a compact 40 mm stroke.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for contactless position feedback. The body length A is 239 mm, giving a total extended length of approximately 279 mm, and the adjustable air cushion (29 mm) ensures smooth deceleration of high-inertia loads.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X40S Is Used
Heavy Part Stops & Gates
The 10053 N push force at 0.5 MPa stops pallets or heavy totes on gravity or powered roller conveyors. The built-in magnet confirms gate position via barrel-mounted sensors.
Industrial Press Feed
Delivers a controlled 40 mm stroke to advance material into a stamping or forming press. The adjustable cushion absorbs impact from the high-inertia load at cycle end.
Clamping & Fixturing
Applies up to 18095 N of clamping force at 0.9 MPa for welding jigs or assembly fixtures. The -S magnet provides a clean sensor signal to interlock the clamp with the machine cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X40S the Right Cylinder?
Choose the SC160 bore when your application needs push forces in the 10053 N (at 0.5 MPa) to 18095 N (at 0.9 MPa) range. If your force requirement is lower, stepping down to an SC125 bore reduces push force to 6136 N at 0.5 MPa. For replacement, match all five key points: 160 mm bore, 40 mm stroke, PT port thread, the built-in magnet (-S), 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 SC160X40S FAQ
At 0.5 MPa the push force is 10053 N, and at 0.7 MPa it reaches 14074 N. The maximum operating force at 0.9 MPa is 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf, though the cylinder is rated for 0.15–1.0 MPa operation.
Yes. The -S suffix indicates a built-in magnet on the piston. AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel without additional brackets, giving you reliable, contactless end-of-stroke or mid-stroke position sensing.
