About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180STC
The AirTAC SC125X180STC is a double-acting tie-rod cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 32 mm piston rod and M27×2 knuckle thread, this 125 mm bore model handles heavy linear work while the 28 mm adjustable air cushion decelerates the 180 mm stroke smoothly.
This specific code includes a built-in magnet (-S) for CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC125TC). The body length A is 203 mm, giving a compact extended length of approximately 383 mm. Operating range is -20 to +70 °C with standard TPU seals on PT ports.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180STC Is Used
Pallet Transfer
The 6136 N push force at 0.5 MPa moves loaded pallets across roller conveyors. The centre trunnion mount lets the cylinder pivot as the transfer arm cycles.
Press-Fit Assembly
At 0.9 MPa the SC125 delivers 11045 N, sufficient for pressing bearings or bushings into heavy housings. Magnetic sensors confirm full extension and retraction.
Damper Gate Actuation
The 32 mm rod and 28 mm cushion handle the inertia of large hopper gates. The TC mount allows the cylinder body to swing with the gate arc.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180STC the Right Cylinder?
The SC125 suits heavy-duty applications where the SC100 (3927 N at 0.5 MPa) is marginal. If your load exceeds 6136 N at 0.5 MPa, step up to the SC160 (10053 N). For this 180 mm stroke, side-load risk is moderate; always guide the load externally if lateral forces are present.
To replace an existing cylinder, match five points: 125 mm bore, 180 mm stroke, PT port thread, centre trunnion TC mount with TCM1 bracket, and the -S magnet for barrel-mounted sensors. The SC is a tie-rod cylinder, shorter than ISO 15552 profiles, so dimensional interchangeability is limited to another AirTAC SC of identical 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 SC125X180STC FAQ
At 0.5 MPa the push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X180STC means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel to detect position.
