About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190S
The SC125X190S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. Its 190 mm stroke, paired with a robust 32 mm piston rod and M27x2 rod thread, suits medium-travel clamping and pressing tasks where consistent thrust is critical.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the tie-rod barrel for contactless position feedback. The adjustable air cushion at each end decelerates the piston over 28 mm to reduce end-of-stroke impact, while the PT1/2 port supplies ample flow for the 125 mm bore.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190S Is Used
Heavy Part Clamping
The 11045 N max push force securely locks large weldments or castings in heavy fabrication fixtures, with sensor confirmation of the clamped position.
Press-Fit Assembly
Delivers controlled, high-force insertion for bearings or bushings into housings. The 190 mm stroke provides clearance for part loading and the magnet confirms cycle completion.
Pallet Stop & Lift
Acts as a robust end-of-line pallet stop or lift station actuator in conveyor systems. The adjustable cushion absorbs the kinetic energy of heavy pallets smoothly.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190S the Right Cylinder?
Choose the SC125 bore when your application needs between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa). If you can work with roughly 3927 N at 0.5 MPa, stepping down to the SC100 bore reduces air consumption and physical size. For strokes at or above 300 mm on this 32 mm rod, evaluate side-load forces carefully—an external linear guide or a guided cylinder assembly prevents rod-bearing bending and premature seal wear.
To match this exact configuration in a replacement scenario, confirm five points: 125 mm bore, 190 mm stroke, PT1/2 ports, the built-in magnet for barrel-mounted sensors, and the basic (no accessory) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X190S FAQ
At 0.5 MPa the push force is 6136 N, and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf, though standard operation is limited to 1.0 MPa.
Yes. The -S suffix in SC125X190S indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the cylinder's tie-rod barrel for reliable, non-contact end-of-stroke or mid-stroke position sensing.
