About the Airtac SE40 Standard Cylinder SE40BX140
The AirTAC SE40BX140 is a double-acting single-rod ISO 15552 profile cylinder engineered for a 40 mm bore and a 140 mm stroke. It supplies a 628 N push force at 0.5 MPa, utilizing an extruded aluminum barrel that omits external tie rods for a flush, corrosion-resistant exterior that mounts cleanly in tight machinery.
This specific SKU is built with a SUS304 stainless steel rod (code B) for corrosive or washdown environments, and operates without a position sensor magnet. Field-adjustable pneumatic cushioning at both ends allows you to tune the end-of-stroke deceleration via a set screw, preventing hard mechanical impacts during high-speed cycling.

Where the Airtac SE40 Standard Cylinder SE40BX140 Is Used
Flow Wrapper End-Seal Jaws
Drives the synchronous cutting and sealing jaws on continuous-motion horizontal flow wrappers, where the 628 N push force reliably overcomes packaging film resistance.
Lab Bottle Rinse Station
Lifts and lowers glass containers through a washdown rinse station, leveraging the SUS304 stainless steel rod to withstand constant moisture and mild cleaning chemicals.
PCB Panel Ejector
Pushes populated printed circuit boards out of an SMT testing fixture using a precise 140 mm stroke, relying on adjustable cushioning to protect delicate solder joints at end stops.
Is the Airtac SE40 Standard Cylinder SE40BX140 the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields a 402 N push at 0.5 MPa; conversely, moving up to the 50 mm bore provides a 982 N push. Because this SE40BX140 configuration lacks a position magnet, it cannot host CMSE or DMSE sensors—add the -S option if your control system requires end-of-stroke confirmation. As a standard ISO 15552 profile cylinder, it serves as a direct dimensional replacement for any equivalent ISO 15552 cylinder utilizing the same PT1/4 port and mounting accessories. Note that a plain double-acting cylinder drifts when air pressure is lost or exhausted; it cannot hold a load statically without live pressure, so specify a BSE rod lock variant if fail-safe holding is mandatory.
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 SE40BX140 FAQ
The SE40BX140 delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 879 N, with a maximum push capacity of 128 kgf at 1.0 MPa. It features a 40 mm bore, 140 mm stroke, PT1/4 port, 16 mm rod, and operates at speeds of 30-800 mm/s.
Yes, the SE40BX140 is dimensionally interchangeable per ISO 15552 standards. Its square extruded profile barrel shares the exact same mounting interface and hole patterns as other ISO 15552 cylinders, allowing it to serve as a direct replacement using your existing mounting hardware and PT1/4 pneumatic fittings.
