About the Airtac SE40 Standard Cylinder SE40BX300SH
The AirTAC SE40BX300SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 40 mm bore and a 300 mm stroke. Because it carries the B rod code, the piston rod is manufactured from SUS304 stainless steel, making it highly suitable for corrosive or washdown settings.
This model features a square extruded aluminum barrel without external tie rods, which keeps the body compact and flush-mountable while resisting corrosion. It is equipped with a high-temperature FKM (Viton) seal, expanding the operating temperature range up to 150 C. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches, while the field-adjustable air cushioning at both ends allows you to tune end-of-stroke deceleration for fast-moving loads.

Where the Airtac SE40 Standard Cylinder SE40BX300SH Is Used
Flow Wrapper Sealing Jaw
Drives the end-seal mechanism on continuous flow packaging machines, where the SUS304 rod resists daily washdowns and the FKM seal withstands frictional heat up to 150 C.
Bottle Conveyor Diverter
Actuates routing gates on high-speed beverage lines, using the 628 N push force at 0.5 MPa to pivot heavy guide arms while CMSE sensors confirm gate position.
Lab Drying Oven Door
Opens and closes insulated doors on industrial drying ovens, leveraging the 300 mm stroke and Viton seals to maintain integrity in ambient temperatures up to 150 C.
Is the Airtac SE40 Standard Cylinder SE40BX300SH the Right Cylinder?
If you need to step down from this 40 mm bore, the 32 mm variant provides 402 N of push at 0.5 MPa, saving space. Conversely, stepping up to the 50 mm bore raises the push force to 982 N at 0.5 MPa for heavier cycles. As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to use existing standardized mounting accessories like FA front flanges or LB foot brackets without redesigning your machine. It uses a PT1/4 port and an M12x1.25 rod thread.
Because this model features a 300 mm stroke, the extended rod is subject to bending moments under side loads; for optimal bearing life, pair it with an external guide rail to prevent rod-bearing wear. Note that the adjustable air cushion only decelerates the piston near the stroke ends and does not hold a load if air pressure is lost—for position holding without live pressure, a BSE rod lock variant or external pilot-operated check valve is required.
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 SE40BX300SH FAQ
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa with a speed range of 30-800 mm/s.
Yes, the SE40BX300SH shares the standardized ISO 15552 / VDMA 24562 mounting footprint, making it a direct dimensional replacement for other ISO 15552 profile cylinders. It uses a PT1/4 port and M12x1.25 rod thread, and its integrated magnet works directly with AirTAC CMSE and DMSE sensors.
