About the Airtac SE125 Standard Cylinder SE125X100S
The AirTAC SE125X100S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It delivers a substantial 6136 N push force at 0.5 MPa, scaling up to 8590 N at 0.7 MPa, making it well-suited for high-thrust industrial operations. The square extruded aluminum barrel omits external tie rods entirely, yielding a compact, corrosion-resistant body that mounts flush against machine frames while maximizing structural integrity.
This 125 mm bore unit includes a built-in magnet (S option) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors. To absorb the significant kinetic energy generated by moving heavy payloads at up to 500 mm/s, it features field-adjustable air cushioning at both ends. Technicians can tune these cushion screws on-site to soften end-of-stroke impacts, ensuring smooth deceleration without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X100S Is Used
Injection Moulding Clamp
Provides the heavy 6136 N push force required to secure large injection moulding machine halves during high-pressure plastic injection cycles.
Hydraulic Press Ejection
Ejects dense formed metal parts from hydraulic presses, utilizing the 100 mm stroke and adjustable cushioning to safely decelerate the 32 mm rod under heavy loads.
Palletizer Lift Gate
Actuates heavy lift gates on automated palletizing systems where the robust 125 mm bore handles substantial pallet weights and the sensor magnet confirms gate position.
Is the Airtac SE125 Standard Cylinder SE125X100S the Right Cylinder?
Selecting the SE125X100S is appropriate when an application demands extreme linear thrust, specifically 6136 N of push force at 0.5 MPa. If a smaller footprint or lower energy consumption is preferred, stepping down to the 100 mm bore yields 3927 N of push at 0.5 MPa; conversely, the 125 mm is the largest standard SE bore available, offering a maximum push capacity of 1252 kgf at 1.0 MPa. Because this is a standard double-acting cylinder, it will drift and cannot hold a load if air pressure is lost or the valve is centered—applications requiring fail-safe load holding must integrate an external rod lock like the BSE variant.
As a true ISO 15552 profile cylinder, the SE125X100S is dimensionally interchangeable with other ISO 15552 cylinders, allowing drop-in retrofits using existing mounting hardware like TC centre trunnions or LB foot brackets. It utilizes a PT1/2 port and a robust Ø32 mm rod with an M27x2 thread. The built-in -S magnet enables precise end-position detection via CMSE or DMSE switches seated in the multi-sided sensor grooves.
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.
