About the Airtac SE125 Standard Cylinder SE125BX100S
The AirTAC SE125BX100S 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, leveraging a 125 mm bore and 100 mm stroke to power demanding industrial operations. The extruded aluminum barrel design omits external tie rods entirely, yielding a highly compact, corrosion-resistant body that mounts flush against machine frames without snagging adjacent components.
Equipped with a SUS304 stainless steel piston rod (material code B), this unit is purpose-built for corrosive or washdown environments where standard carbon steel rods would fail. The integrated -S magnet enables seamless position tracking using AirTAC CMSE reed or DMSE electronic sensors, while the field-adjustable pneumatic cushioning at both stroke ends allows technicians to fine-tune deceleration and eliminate hard mechanical impacts at high travel speeds.

Where the Airtac SE125 Standard Cylinder SE125BX100S Is Used
Heavy Press Stamping
Provides the 6136 N push force at 0.5 MPa required to drive stamping dies and form thick-gauge sheet metal in automated fabrication lines.
Washdown Clamping
Leverages the SUS304 stainless steel rod to securely clamp large molds during food-processing equipment wash cycles without risking surface corrosion.
Pallet Lift Actuation
Raises and lowers heavy loaded pallets in packaging dispatch zones, using the 100 mm stroke and adjustable end-cushions to soften the final stopping impact.
Is the Airtac SE125 Standard Cylinder SE125BX100S the Right Cylinder?
Selecting the SE125BX100S is appropriate when your application requires maximum thrust, as it generates 6136 N of push at 0.5 MPa. If your load requirements are lighter, stepping down to the 100 mm bore model reduces energy consumption while still providing a robust 3927 N push at 0.5 MPa. Conversely, this 125 mm bore represents the maximum standard size in the SE range, meaning larger force demands will require a custom or dual-cylinder configuration. Because this is a double-acting cylinder, it relies on continuous air pressure to maintain its position; if a load must be held mechanically during an air loss event, consider the BSE rod-lock variant or an external pilot-operated check valve. For dimensionally interchangeable retrofits, this cylinder matches the ISO 15552 mounting footprint, utilizes a PT1/2 port, and pairs with standard FA or LB mounting hardware.
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 SE125BX100S FAQ
