About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X360S
The AirTAC SC125X360S is a double-acting single-rod pneumatic cylinder delivering a push force of 6136 N at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 125 mm bore, 32 mm piston rod, and a 360 mm stroke, it is sized for heavy pressing, clamping, and lifting tasks where substantial force is needed in a compact tie-rod format.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, and the PT1/2 port thread ensures straightforward pneumatic connections. Total body length A is 203 mm, giving an extended length of approximately 563 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X360S Is Used
Heavy Press & Assembly
Provides 11045 N at 0.9 MPa for pressing bearings, riveting, or forming operations. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Palletising & Lifting
Delivers consistent 6136 N push force at standard shop air for lifting and positioning heavy pallets or containers on automated lines.
Clamping & Fixturing
Used in heavy welding jigs and machining fixtures where the adjustable cushion prevents impact damage and the magnet provides clamp-status feedback.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X360S the Right Cylinder?
The SC125 bore sits in the heavy-duty class, with the SC100 offering 3927 N at 0.5 MPa for lighter loads and the SC160 stepping up to 10053 N for the most demanding applications. For this 360 mm stroke, ensure the load is guided externally if side forces are present—the 32 mm rod can experience bending under unsupported lateral loads at longer extensions. A guided cylinder or external linear guide is recommended.
To replace an existing cylinder, match five points: 125 mm bore, 360 mm stroke, PT1/2 port thread, the basic mounting (no pre-attached bracket), and the built-in magnet for sensor compatibility. This is an ISO 6430 class tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC or equivalent tie-rod designs.
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 SC125X360S 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 force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix denotes a built-in magnet, so you can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
