About the Airtac SE40 Standard Cylinder SE40BX125S
The AirTAC SE40BX125S is a double-acting, single-rod ISO 15552 profile cylinder engineered for precise linear motion. It delivers a robust 628 N push force at 0.5 MPa alongside a 528 N pull force, making it well-suited for mid-range automation tasks. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight machine layouts.
This specific configuration features a SUS304 stainless steel piston rod (code B) for superior resistance in washdown or corrosive manufacturing environments. Equipped with a built-in magnet (code S), it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors for exact end-of-stroke detection. Field-adjustable air cushions at both ends allow you to dial in deceleration, softening hard end stops during 125 mm travel.

Where the Airtac SE40 Standard Cylinder SE40BX125S Is Used
Flow Wrapper Sealing
Drives the sealing jaw on a continuous flow wrapper, utilizing the 628 N push force to cleanly cut and seal packaging film at high speeds.
Lab Sample Dispensing
Actuates a multi-port valve for chemical sample dispensing, where the SUS304 rod prevents corrosion from accidental chemical exposure.
Bottle Diverting Gate
Powers a diverter gate on a bottling line, relying on the 125 mm stroke to shift containers between conveyor lanes smoothly.
Is the Airtac SE40 Standard Cylinder SE40BX125S the Right Cylinder?
If your application requires less force, the 32 mm bore offers a 402 N push at 0.5 MPa, whereas stepping up to the 50 mm bore provides a 982 N push for heavier loads. As a dimensionally interchangeable ISO 15552 cylinder, this 40 mm bore with a 125 mm stroke, PT1/4 port, and SUS304 rod serves as a direct replacement for other ISO 15552 profile cylinders. Remember that an unpowered SE cylinder cannot hold a load mid-stroke; if position holding without live air pressure is required, consider a BSE rod lock variant.
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 SE40 Standard Cylinder SE40BX125S FAQ
