About the Airtac SE50 Standard Cylinder SE50BX290S
The AirTAC SE50BX290S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding automation environments. It delivers a robust 982 N push force at 0.5 MPa alongside an 825 N pull, utilizing a 50 mm bore and 290 mm stroke. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while maintaining strict ISO 15552 dimensional interchangeability.
This specific configuration features a SUS304 stainless steel rod (code B) for superior resistance in washdown or corrosive settings, and includes a built-in magnet (code S) for non-contact position sensing. The piston speed operates seamlessly across a 30-800 mm/s range, and field-adjustable air cushions at both stroke ends allow technicians to fine-tune deceleration, softening hard mechanical stops during high-velocity cycling.

Where the Airtac SE50 Standard Cylinder SE50BX290S Is Used
Flow Wrapper End-Seal Jaw
Driving the mechanical knife assembly on horizontal flow wrappers, where the 982 N push force reliably cuts and seals packaging film at high cyclic rates without deflecting the rod.
Lab Sample Carousel Indexing
Rotating sample carousels in automated hematology analyzers, leveraging the SUS304 stainless rod and -S magnet to trigger CMSE/DMSE sensors for precise 290 mm linear positioning.
Pallet Transfer Pusher
Advancing heavy pallets off a main conveyor line onto a secondary spur, utilizing the full 290 mm stroke and adjustable pneumatic cushions to absorb the kinetic energy of the load at stroke end.
Is the Airtac SE50 Standard Cylinder SE50BX290S the Right Cylinder?
When sizing this actuator, consider stepping down to the 40 mm bore if your application requires less than 628 N of push force at 0.5 MPa, or scaling up to the 63 mm bore if you need to exceed the 1559 N threshold. Because the 290 mm stroke generates extended leverage, long unsupported piston travel introduces rod-bearing bending moments; an external guide is highly recommended to prevent premature seal wear and binding. As a standard ISO 15552 cylinder, it serves as a direct replacement sharing the 50 mm bore, 290 mm stroke, PT1/4 port, and standard mounting interface. Note that the adjustable end cushions only decelerate the piston near stroke completion and do not hold a load; if the air supply is lost, the rod will drift. For position holding, a BSE rod lock variant 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 SE50 Standard Cylinder SE50BX290S FAQ
The SE50BX290S generates 982 N push and 825 N pull at 0.5 MPa, and 1374 N push at 0.7 MPa. It reaches a maximum push force of 200 kgf at its 1.0 MPa operating pressure limit.
No, the SE50BX290S is a standard double-acting cylinder and the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock or hold a load. If pressure is lost, the rod will drift. For true position holding, an AirTAC BSE rod lock cylinder is required.
