About the Airtac SE125 Standard Cylinder SE125X75SN
The AirTAC SE125X75SN 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, utilizing a 125 mm bore and 75 mm stroke. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush in tight machinery spaces.
This specific configuration includes a built-in magnet for CMSE and DMSE position sensing, alongside an NBR seal suited for standard ambient temperatures. The field-adjustable air cushion at both ends allows technicians to dial in end-of-stroke deceleration, protecting heavy 125 mm payloads from harsh mechanical impacts.

Where the Airtac SE125 Standard Cylinder SE125X75SN Is Used
Automotive Stamping Presses
Provides the 6136 N push force required to actuate heavy-duty blanking dies and hold large metal panels securely in position during high-force stamping operations.
Heavy-Duty Metal Bending
Drives robust press brakes and thick-plate bending fixtures, utilizing the 125 mm bore capacity and adjustable end-cushions to smoothly decelerate massive forming tools.
Palletizer Ejection Arms
Powers the heavy ejection and sorting arms on automated palletizing lines, moving substantial packaged goods rapidly via the 75 mm stroke without harsh end-impacts.
Is the Airtac SE125 Standard Cylinder SE125X75SN the Right Cylinder?
Choosing this 125 mm bore provides maximum thrust, generating 6136 N push at 0.5 MPa. If your application requires slightly less force, the adjacent 100 mm bore yields 3927 N push at 0.5 MPa. Since this is the largest standard SE size, stepping up beyond 125 mm requires custom or multi-cylinder solutions. Keep in mind that a plain SE cylinder cannot hold a load if air pressure drops; for vertical load-holding safety, consider the BSE rod-lock variant.
As a dimensionally interchangeable ISO 15552 cylinder, this model allows drop-in replacement using existing mounting hardware and PT1/2 pneumatic ports. The integrated -S magnet supports CMSE and DMSE sensors, while the NBR seal handles standard operating environments reliably.
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.
