About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200H
The AirTAC SC125X200H is a double-acting tie-rod cylinder engineered for high-temperature environments, using Viton (FKM) seals to operate reliably from 0 to +150°C. With a 125 mm bore and 200 mm stroke, it generates a substantial push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa, making it a powerful actuator for demanding industrial tasks.
This model features a 32 mm piston rod with an M27x2 thread and a 28 mm adjustable air cushion at each end for smooth deceleration. The body length A is 203 mm, giving a total extended length of approximately 403 mm. As a genuine AirTAC SC series cylinder, it offers a compact tie-rod design that is shorter than an equivalent ISO 15552 profile, ideal for space-constrained installations.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200H Is Used
High-Temperature Pressing
Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it suitable for pressing, clamping, or forming operations near ovens, autoclaves, or heated platens where standard seals would fail.
Heavy Material Handling
With over 11000 N of force at 0.9 MPa, the SC125X200H can push, lift, or position heavy components on assembly lines, in foundries, or in metal fabrication shops requiring robust, heat-resistant actuation.
Test & Durability Rigs
The combination of a 200 mm stroke and high force output is ideal for test stands and life-cycle rigs in hot environments, where consistent, repeatable linear motion is needed to cycle components under load.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200H the Right Cylinder?
Select the SC125 when your application requires a force class around 6136 N at 0.5 MPa. If you need slightly less force in a smaller package, step down to the SC100 bore (3927 N at 0.5 MPa). For higher force demands, the SC160 bore delivers 10053 N at the same pressure. Always match the bore, 200 mm stroke, PT port thread, and basic mounting when replacing an existing unit.
For this 200 mm stroke, the standard tie-rod construction provides adequate rigidity for purely axial loads. However, if any side load is present, use an external guide or a guided cylinder to protect the 32 mm rod and bearing from bending stress, which can cause premature seal wear.
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 SC125X200H FAQ
At the standard operating pressure of 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 increases to 11045 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with the same bore, stroke, PT ports, and basic mounting.
