About the Airtac SE50 Standard Cylinder SE50BX550S
The AirTAC SE50BX550S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 550 mm stroke. It delivers 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, utilizing a PT1/4 port and a 20 mm rod with an M16x1.5 thread. The square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant body that mounts cleanly in tight spaces.
This specific configuration features a SUS304 stainless steel rod for corrosive and washdown environments, alongside a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration, protecting the mechanism during high-speed 30-800 mm/s cycles.

Where the Airtac SE50 Standard Cylinder SE50BX550S Is Used
Stainless Food Conveyor Diverter
The SUS304 rod withstands washdown chemicals while providing 982 N push to actuate diverters on a food packaging line over its 550 mm stroke.
Palletizer Lowerator Arm
Uses the 550 mm stroke to lower heavy cardboard stacks, relying on adjustable pneumatic cushions to soften the 1374 N impact at 0.7 MPa.
Bottling Line Gate Actuator
Drives a heavy flow-control gate on a beverage line, utilizing the built-in magnet for DMSE electronic sensors to verify gate position.
Is the Airtac SE50 Standard Cylinder SE50BX550S the Right Cylinder?
If 982 N push at 0.5 MPa is excessive for your payload, stepping down to the 40 mm bore drops output to 628 N. Conversely, scaling up to the 63 mm bore raises push force to 1559 N. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or a valve centers; applications requiring true position holding without live pressure must integrate an external rod lock or pilot-operated check valve.
At 550 mm, this unit approaches the upper end of standard strokes, making the 20 mm rod and M16x1.5 thread critical for carrying side loads. For long unsupported strokes, always specify an external guide to prevent rod-bearing bending and premature seal wear. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement sharing standard mounting hardware, the PT1/4 port, and the -S magnet footprint.
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 SE50 Standard Cylinder SE50BX550S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force increases to 1374 N. The absolute maximum push force is 200 kgf at 1.0 MPa.
No, the SE50BX550S is a standard double-acting cylinder and the adjustable air cushion only decelerates the piston near stroke end; it does not lock or hold a load. If position holding without live pressure is required, you must use an external rod lock or a BSE series cylinder.
