About the Airtac SE50 Standard Cylinder SE50BX350SH
The AirTAC SE50BX350SH is a double-acting ISO 15552 profile cylinder engineered for demanding washdown and high-temperature environments. Delivering 982 N of push force at 0.5 MPa and featuring a 350 mm stroke, it integrates a SUS304 stainless steel rod and FKM Viton seals to operate reliably up to 150 degrees Celsius. The extruded aluminum barrel omits external tie rods, yielding a smooth, flush-mounted body that resists debris buildup and corrosion.
This model includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic position sensors. Field-adjustable pneumatic cushioning at both stroke ends allows you to dial in end-of-travel deceleration, softening hard impacts when cycling at speeds up to 800 mm/s. It is a true VDMA 24562 interchange cylinder, sharing the exact mounting footprint of other ISO 15552 actuators.

Where the Airtac SE50 Standard Cylinder SE50BX350SH Is Used
Bottle Filler Capping
Drives capping heads on a beverage line using its 982 N push force and 350 mm stroke, where the SUS304 rod and FKM seals withstand harsh chemical washdowns and high-temperature sterilization cycles.
Pallet Deflection Gate
Actuates a routing diverter on a packaging conveyor, utilizing the 350 mm stroke to fully clear the pallet path while the adjustable air cushions soften the extended stop at high transit speeds.
Injection Mold Ejector
Pushes finished plastic parts out of a hot injection molding tool, relying on the FKM Viton seals to survive ambient radiant heat up to 150 degrees Celsius without degrading.
Is the Airtac SE50 Standard Cylinder SE50BX350SH the Right Cylinder?
Selecting this 50 mm bore makes sense when your application requires 982 N of push force at 0.5 MPa. If you need less force, stepping down to the 40 mm bore yields 628 N push, while moving up to the 63 mm bore provides 1559 N push for heavier payloads. Remember that a plain SE cylinder drifts when air is removed or a valve is centered; if your process must hold a load without live pressure, consider the BSE rod lock variant.
At 350 mm of stroke, the 20 mm rod and thread experience increased bending moments under side loads, making an external guide rail advisable to prevent premature bearing wear. For retrofitting, match the 50 mm bore, 350 mm stroke, PT1/4 port, and your specific mounting accessory. The included -S magnet enables CMSE or DMSE sensor tracking without extra hardware.
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.
