About the Airtac SE40 Standard Cylinder SE40BX300
The AirTAC SE40BX300 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 40mm bore and 300mm stroke. It yields 628 N of push force at 0.5 MPa, extending via a 16mm SUS304 stainless steel rod. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against frames while resisting mechanical snagging in tight machine cells.
This unit lacks a built-in magnet, so it does not support CMSE or DMSE position sensors without modification. To protect internal seals and rod bearings over the 300mm travel, field-adjustable pneumatic cushioning at both ends allows technicians to dial in end-of-stroke deceleration via a setscrew, softening hard impacts at operating speeds up to 800 mm/s.

Where the Airtac SE40 Standard Cylinder SE40BX300 Is Used
Stainless Form-Fill Seal Jaws
Drives the sealing jaws on a washdown packaging line, using the 628 N push force and SUS304 rod to withstand daily chemical sanitation without pitting.
Bottle Divert Gate Actuator
Actuates a diverting gate arm over 300mm of travel on a beverage conveyor, relying on the adjustable cushion to softly stop the mass of the swinging arm at high speed.
Lab Sample Drawer Ejector
Extends a 300mm tray to eject sample racks from an automated testing machine, where the smooth extruded profile barrel prevents glove snags during manual retrieval.
Is the Airtac SE40 Standard Cylinder SE40BX300 the Right Cylinder?
At 0.5 MPa, this 40mm bore generates 628 N of push force. If your assembly requires less thrust, the neighboring 32mm bore provides 402 N; if your fixture demands more clamping power, step up to the 50mm bore for 982 N. Because the 300mm stroke creates leverage that can bend the 16mm rod under lateral stress, an external guide rail is strongly recommended to prevent side-load bearing wear.
This SKU uses a PT1/4 port and a standard Basic mounting footprint. It is dimensionally interchangeable per ISO 15552, meaning it drops directly into existing profiles sharing the same 40mm bore and stroke envelope. Note that a plain SE cylinder will drift if air pressure is lost; use a BSE rod lock variant if the load must be held vertically without live pressure.
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 SE40BX300 FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force reaches 879 N. The maximum push force is 128 kgf at 1.0 MPa operating pressure.
Yes, the SE40BX300 is dimensionally interchangeable per ISO 15552 standards. It shares the exact mounting footprint, PT1/4 port, and 300mm stroke dimensions of other 40mm ISO 15552 profile cylinders, allowing a direct retrofit without modifying the machine plate.
