About the Airtac SE125 Standard Cylinder SE125X200
The AirTAC SE125X200 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a substantial 6136 N push force at 0.5 MPa and features a PT1/2 port paired with a robust Ø32 mm rod. The extruded aluminum barrel omits external tie rods, yielding a sleek, corrosion-resistant body that mounts flush against machine frames while maintaining the standardized ISO 15552 footprint.
This 125 mm bore unit relies on field-adjustable air cushions at both ends to decelerate the piston smoothly, preventing harsh end-stop impacts during high-speed actuation. Note that this specific SKU lacks a built-in magnet, so it does not support CMSE or DMSE position sensing without modification. The cushioning is strictly for end-of-stroke energy absorption and is not a locking mechanism.

Where the Airtac SE125 Standard Cylinder SE125X200 Is Used
Automotive Stamping Presses
Drives heavy stamping and holding fixtures in automotive assembly lines, utilizing the 6136 N push force to secure high-strength steel panels during machining operations.
Plastic Injection Molding
Actuates large molds and heavy ejector mechanisms, where the 200 mm stroke and adjustable end-cushions absorb kinetic energy from substantial moving platens.
Palletizer Tooling
Operates heavy-duty lift and clamp assemblies on robotic palletizers, leveraging the robust 32 mm rod to manage significant side loads during box placement.
Is the Airtac SE125 Standard Cylinder SE125X200 the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder is the largest standard size in the SE lineup. If your application requires less force, stepping down to the 100 mm bore yields 3927 N of push, which may be more efficient for lighter loads. As the maximum bore, there is no larger standard option in this series. Because the stroke is 200 mm, the 32 mm rod and M27x2 thread handle moderate side loads, but any extended unsupported travel requires an external guide to prevent rod-bearing bending. Remember that a standard SE does not hold its position when air pressure is lost; if your load must remain fixed without live pressure, integrate a BSE rod lock. This model is dimensionally interchangeable with other ISO 15552 cylinders for seamless retrofitting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X200 FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force reaches 8590 N. The maximum push force is 1252 kgf at 1.0 MPa. It operates at a speed of 30-500 mm/s.
It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders. However, it does not hold a load when air is lost; for position holding, use a BSE rod lock variant. The adjustable cushions only decelerate the piston near stroke end.
