About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190
The SC125X190 is a robust tie-rod cylinder from AirTAC, delivering a substantial 6136 N of push force at a standard 0.5 MPa supply pressure. With a 125 mm bore and a 190 mm stroke, this double-acting unit is designed for heavy industrial applications requiring high force in a compact linear envelope.
This model features a 32 mm piston rod with an M27x2 thread and a 28 mm adjustable air cushion at each end to decelerate high-inertia loads. The body length A is 203 mm, making the total extended length approximately 393 mm. As an ISO 6430 class cylinder, it is built for demanding duty cycles.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190 Is Used
Heavy Press & Clamping
Generates over 11000 N at 0.9 MPa, ideal for hydraulic-press alternatives, heavy-duty clamping fixtures, and riveting stations requiring controlled, high-force linear motion.
Material Transfer & Lift
The 190 mm stroke and high push force suit pallet lifts, heavy part pushers on conveyor lines, and bin tippers in manufacturing or recycling facilities.
Industrial Machinery Actuation
Used in sawmill carriages, compacting equipment, and large valve actuation where a rugged, repairable tie-rod cylinder provides reliable service in harsh environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190 the Right Cylinder?
Select the SC125X190 when your application requires roughly 6000 N of force. If your load is lighter, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa, potentially saving space and air consumption. For strokes of 190 mm, the rigid 32 mm rod handles direct axial loads well, but any side loading requires an external guide or rod support to prevent bending and premature seal wear.
For a direct replacement, match five key points: 125 mm bore, 190 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a magnet. This ensures the new cylinder fits your existing tie-rod mounting footprint and pneumatic connections.
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 SC125X190 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.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a comparable ISO 15552 profile cylinder. It is not a drop-in replacement for ISO 15552 dimensions. For a direct fit, replace with another AirTAC SC125 tie-rod cylinder matching your stroke, port, and mounting.
