About the Airtac SE40 Standard Cylinder SE40BX40SN
The AirTAC SE40BX40SN is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering 628 N of push force at 0.5 MPa. It features a robust Ø16 mm rod with an M12x1.25 thread and a PT1/4 port, making it highly effective for short-stroke clamping and ejection tasks.
Built with a SUS304 stainless steel rod and an NBR seal, this unit is configured for washdown and mildly corrosive environments. The square extruded aluminum barrel eliminates external tie rods for a flush mounting profile, while the integrated magnet supports CMSE reed and DMSE electronic sensors for precise end-of-trroke detection.

Where the Airtac SE40 Standard Cylinder SE40BX40SN Is Used
Stainless Parts Ejection
Utilizing the 628 N extend force and SUS304 rod, this cylinder pushes machined stainless fittings out of a CNC lathe, enduring coolant splash without rod degradation.
Pouch Flap Sealing
The 40 mm stroke provides rapid, short-traction movement to press packaging flaps on a form-fill-seal machine, using the NBR seal to handle humid production zones.
Lab Sample Diverting
Equipped with a DMSE electronic sensor, it actuates a 40 mm swing gate to sort laboratory vials, relying on the compact tie-rod-free barrel to fit tight equipment frames.
Is the Airtac SE40 Standard Cylinder SE40BX40SN the Right Cylinder?
If your application requires less force, the adjacent 32 mm bore yields 402 N of push at 0.5 MPa, whereas stepping up to the 50 mm bore provides 982 N for heavier loads. To match this exact ISO 15552 footprint, specify a 40 mm bore, 40 mm stroke, PT1/4 port, and your preferred mounting accessory. Note that a plain SE cylinder relies on live air pressure to maintain its position; if the air supply drops, the piston will drift, so integrate a BSE rod lock for fail-safe holding.
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 SE40BX40SN FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force reaches 879 N, with a maximum push capacity of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE40BX40SN is dimensionally interchangeable per ISO 15552 standards, allowing it to drop into existing 40 mm bore mounting footprints. The field-adjustable air cushion at both ends can be tuned to soften end stops without changing the mounting hardware.
