Airtac SE125 Standard Cylinder SE125X145
The AirTAC Airtac SE125 Standard Cylinder SE125X145 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 145mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X145
The AirTAC SE125X145 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while retaining the standardized ISO 15552 footprint.
This 125mm bore unit features a robust Ø32 mm piston rod and PT1/2 ports. It integrates field-adjustable air cushioning at both ends to tame the kinetic energy of large moving masses, and because this specific SKU lacks the -S magnet code, it arrives without built-in position sensing.

Where the Airtac SE125 Standard Cylinder SE125X145 Is Used
Injection Mold Clamping
Supplies the 6136 N push force required to secure heavy injection mold halves during material injection cycles.
Hydraulic Press Ejection
Ejects dense formed metal components from a hydraulic press, utilizing the 40mm cushion length to soften end-of-stroke impacts.
Structural Beam Bending
Applies slow, high-thrust pressure to bend thick structural steel beams within heavy fabrication jigs.
Is the Airtac SE125 Standard Cylinder SE125X145 the Right Cylinder?
Selecting this 125mm bore provides maximum thrust, but if your application does not require 6136 N of push at 0.5 MPa, stepping down to the 100mm bore yields 3927 N and saves valuable space. Conversely, this is the largest standard SE bore available. For stroke lengths like 145mm, side-load stress on the rod bearing is moderate, but always verify alignment. As a double-acting cylinder, it cannot hold a load if air pressure drops; use a BSE rod lock for fail-safe holding. It serves as a direct dimensional drop-in for any ISO 15552 cylinder.
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 SE125X145 FAQ
At 0.5 MPa, this 125mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
