About the Airtac SE40 Standard Cylinder SE40BX300SLB
The AirTAC SE40BX300SLB is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 40 mm bore and 300 mm stroke. It delivers 628 N of push force at 0.5 MPa and operates at speeds between 30-800 mm/s. Equipped with a SUS304 stainless steel rod, it is specifically built for corrosive and washdown environments where standard carbon steel rods would fail.
Unlike traditional round-body or tie-rod designs, this cylinder utilizes a square extruded aluminum barrel without external tie rods, making it compact and highly resistant to corrosion while allowing for flush mounting. The integrated magnet (-S) enables seamless position feedback when paired with AirTAC CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a screw, softening hard mechanical stops during high-speed operations.

Where the Airtac SE40 Standard Cylinder SE40BX300SLB Is Used
Flow Wrapper End-Sealing
Drives the end-sealing jaw mechanism on a continuous flow wrapper, utilizing the 628 N push force and 300 mm stroke to cleanly crimp and cut packaging film at speed.
Lab Washdown Station
Actuates spray manifolds in a pharmaceutical cleanroom, relying on the SUS304 stainless steel rod to withstand harsh chemical sterilization without degrading.
Pallet Diversion Gate
Powers a lateral diverting gate on a 24V DC conveyor line, using the built-in magnet to trigger CMSE sensors and confirm gate open/close positions.
Is the Airtac SE40 Standard Cylinder SE40BX300SLB the Right Cylinder?
If your application requires less force, the adjacent SE32 bore provides 402 N of push at 0.5 MPa; conversely, stepping up to the SE50 bore yields 982 N. Because this configuration features a 300 mm stroke, the unsupported rod length increases the risk of side-load bending at the rod bearing, making an external guide highly recommended to prevent premature wear. As a standard ISO 15552 profile cylinder, this model serves as a direct replacement for any ISO 15552 cylinder, matching the 40 mm bore, 300 mm stroke, PT1/4 port, LB foot mounting, and -S magnet specifications. Remember that a plain SE cylinder does not hold loads when air is lost; for position holding, consider the 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 SE40BX300SLB FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. 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 SE40BX300SLB is dimensionally interchangeable per ISO 15552 standards. It shares the exact mounting footprint, PT1/4 port size, and M12x1.25 rod thread, allowing it to drop in as a replacement for other ISO 15552 profile cylinders without modifying the machine frame.
