About the Airtac SE125 Standard Cylinder SE125X1300S
The AirTAC SE125X1300S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a formidable 6136 N of push force at 0.5 MPa and features a 1300 mm stroke. This stroke length exceeds the standard 1500 mm maximum catalog stroke configuration for this bore, making it a non-standard, made-to-order actuator built for specialized, long-reach machinery.
The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight frames. Equipped with a built-in magnet (-S), the cylinder integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Field-adjustable air cushions at both ends allow technicians to tune end-stop deceleration, softening the impact of heavy 125 mm pistons traveling at speeds up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X1300S Is Used
Heavy Pallet Lifts
Drives the main elevation carriage in automated palletizer systems, utilizing the 6136 N push force to lift heavy goods across a 1300 mm vertical travel distance.
Automated Press Frames
Applies steady clamping pressure on large sheet metal or composite panels in multi-stage press lines, leveraging the 125 mm bore's high thrust capacity.
Long-Stroke Bending Dies
Actuates heavy-duty forming and bending dies requiring an extended 1300 mm reach, where the adjustable cushion absorbs the massive kinetic energy at stroke end.
Is the Airtac SE125 Standard Cylinder SE125X1300S the Right Cylinder?
Selecting the SE125X1300S is appropriate when maximum thrust is the priority, as stepping down to the 100 mm bore reduces your 0.5 MPa push force to 3927 N. Since this is the largest standard bore, there is no larger neighbor to step up to. The 1300 mm stroke demands careful attention to physics: at full extension, the 32 mm rod and bearing face significant bending moments from any side load. An external guide or linear rail is strongly recommended to prevent premature seal wear and piston drift.
This cylinder is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing you to drop it into existing machinery footprints without redesigning mounting plates. To retrofit, match the 125 mm bore, 1300 mm stroke, PT1/2 port, and your required mounting accessory. Remember that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking mechanism. If the application must hold a load statically without live air pressure, use a BSE rod lock variant or an external pilot-operated check valve.
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 SE125X1300S FAQ
The SE125X1300S provides a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. The 1300 mm stroke is non-standard, meaning it is manufactured as a made-to-order item.
Yes, the built-in magnet (-S) is specifically designed to trigger AirTAC CMSE reed switches and DMSE electronic sensors. Furthermore, its ISO 15552 mounting dimensions make it a drop-in replacement for other ISO 15552 profile cylinders, simplifying retrofits.
