Airtac SE125 Standard Cylinder SE125X105
The AirTAC Airtac SE125 Standard Cylinder SE125X105 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 105mm 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 SE125X105
The AirTAC SE125X105 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It generates a substantial 6136 N of push force at 0.5 MPa and utilizes a PT1/2 port to drive its 32 mm rod. The extruded aluminum barrel design completely omits external tie rods, yielding a smooth, corrosion-resistant body that mounts flush against machine frames while leaving three integrated sensor grooves open for external position switches.
This specific SKU is built without a built-in magnet, meaning it is not wired for CMSE or DMSE electronic position sensing out of the box. To manage high kinetic energy at end-of-stroke, the cylinder incorporates a field-adjustable air cushion at both ends with a 40 mm cushioning length. This allows technicians to dial in the exact deceleration rate via a set screw, preventing harsh mechanical impacts during high-speed 30-500 mm/s cycling.

Where the Airtac SE125 Standard Cylinder SE125X105 Is Used
Plastic Injection Molding
Provides the 6136 N push force required to open and close heavy molds on mid-sized injection molding presses, using its adjustable cushion to soften the final stop.
Metal Forming Press
Drives a 105 mm stroke to execute deep-draw bending operations on heavy-gauge sheet metal, capitalizing on the 8590 N thrust available at 0.7 MPa.
Pallet Lifting Gate
Actuates the primary lifting arms on automated pallet gates, where the smooth tie-rod-free profile prevents debris buildup in dusty warehouse environments.
Is the Airtac SE125 Standard Cylinder SE125X105 the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder sits at the top of the SE standard range. If your application requires less force, stepping down to the 100 mm bore yields 3927 N of push at 0.5 MPa; however, there is no larger standard SE bore available if you need to scale up. Because this model lacks the -S magnet code, it cannot host CMSE or DMSE sensors without modification, so if your sequence control relies on position feedback, you would need an alternative detection method. Furthermore, if your process demands holding a load securely without continuous air pressure, remember that the adjustable air cushion only decelerates the piston near the stroke ends and does not act as a brake; an external pilot-operated check valve or the BSE rod-lock variant is required for true holding torque. For any stroke at or above 300 mm, you must account for rod-bearing bending under side loads by incorporating an external guide.
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 SE125X105 FAQ
