About the Airtac SE125 Standard Cylinder SE125BX150
The AirTAC SE125BX150 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 6136 N push force at 0.5 MPa. Designed with a 125 mm bore and 150 mm stroke, it features a field-adjustable air cushion at both ends to precisely tune end-of-stroke deceleration for massive moving loads. This specific SKU utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsh or washdown environments.
Unlike traditional tie-rod designs, its square extruded aluminum barrel integrates sensor grooves on three sides, allowing flexible mounting of position switches without extra brackets. Note that this configuration ships without a built-in magnet, meaning it is optimized for purely mechanical drive applications where electronic CMSE or DMSE position feedback is not required. Operating at speeds up to 30-500 mm/s, it handles substantial dynamics while maintaining a standardized ISO 15552 / VDMA 24562 mounting footprint for seamless machine retrofits.

Where the Airtac SE125 Standard Cylinder SE125BX150 Is Used
Heavy Press Stamping
Drives large metal forming presses where the 6136 N push force at 0.5 MPa securely seats stamping dies and forms thick-gauge automotive chassis components.
Palletizer Ejection
Ejects heavy completed pallets from stretch-wrapping stations, utilizing the 150 mm stroke and SUS304 rod to withstand incidental debris and harsh industrial environments.
Wastewater Screen Cleaning
Actuates mechanical bar-screen rakes in municipal wastewater treatment plants, leveraging the SUS304 stainless rod to resist constant chemical and moisture exposure.
Is the Airtac SE125 Standard Cylinder SE125BX150 the Right Cylinder?
Selecting the SE125BX150 places you at the top of the standard SE range, offering 6136 N of thrust at 0.5 MPa and a maximum 1252 kgf output at 1.0 MPa. If your application does not require this peak force, stepping down to the 100 mm bore yields 3927 N of push, saving space and air consumption. Conversely, if you need to hold a load statically without live air pressure, this standard cylinder will drift; you must integrate an external pilot-operated check valve or pivot to the BSE rod-lock variant. Furthermore, while the SUS304 rod and M27x2 thread provide excellent rigidity, any stroke over 300 mm on this platform necessitates an external guide to prevent rod-bearing bending under heavy side loads. For retrofitting, ensure your setup matches the PT1/2 port and standard ISO 15552 mounting accessories.
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 SE125BX150 FAQ
The SE125BX150 delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, allowing it to drop into existing footprints using standard mounting hardware. This specific SKU lacks the -S magnet, so it does not support CMSE or DMSE position sensors out of the box.
