About the Airtac SE125 Standard Cylinder SE125X500
The AirTAC SE125X500 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a formidable 6136 N of push force at 0.5 MPa. Its square extruded aluminum barrel completely eliminates external tie rods, yielding a highly compact, corrosion-resistant body that mounts flush against machine frames while exposing no external hardware to impact damage. This clean profile also integrates standardized sensor grooves on three sides of the barrel, allowing position switches to be slotted in seamlessly wherever the mounting layout permits.
This specific configuration features a 500 mm stroke driven by a robust Ø32 mm piston rod with an M27x2 thread, operating at speeds between 30-500 mm/s via its PT1/2 port. Because this SKU lacks the -S magnet code, it does not support the CMSE or DMSE electronic position sensors out of the box, relying instead on external limit detection. Field-adjustable air cushions at both ends allow technicians to dial in end-of-stroke deceleration via a set screw, softening hard mechanical stops to protect heavy 1252 kgf payloads from sudden impact shock.

Where the Airtac SE125 Standard Cylinder SE125X500 Is Used
Injection Mold Clamping
Provides 6136 N of push at 0.5 MPa to secure heavy injection mold halves during the material injection phase, utilizing the adjustable cushion to soften the 500 mm closure.
Hydraulic Press Ejection
Delivers up to 1252 kgf at 1.0 MPa to eject dense metal or composite stamped parts from a hydraulic press bed, absorbing the sudden load shift with its 40 mm cushion stroke.
Palletizer Lift Arm
Drives a 500 mm vertical lift mechanism for heavy palletized goods, relying on the rigid Ø32 mm rod and M27x2 thread to handle high dynamic side loads when repositioning.
Is the Airtac SE125 Standard Cylinder SE125X500 the Right Cylinder?
When sizing this 125 mm bore actuator, evaluate your exact load requirements to step up or down effectively. If 6136 N of push at 0.5 MPa is excessive for your application, stepping down to the 100 mm bore provides a more modest 3927 N push, optimizing air consumption. Conversely, if your system demands extreme thrust beyond the 8590 N push available at 0.7 MPa, the 125 mm bore is the largest standard ISO 15552 option in this series, meaning you must either increase supply pressure toward the 1.0 MPa maximum or explore twin-cylinder configurations.
For a 500 mm stroke, the unsupported mass of the extended Ø32 mm rod creates a measurable bending moment on the front bearing cap. To prevent premature seal wear and rod deflection, an external guide rail should be used to support the load. Note that while the adjustable end cushions decelerate the piston near stroke end, this cylinder cannot hold a load in place if air pressure is lost; a BSE rod lock variant or external pilot-operated check valve is required for fail-safe positioning.
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 SE125X500 FAQ
