About the Airtac SE32 Standard Cylinder SE32X550S
The AirTAC SE32X550S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. Delivering 402 N of push force at 0.5 MPa, it utilizes a 32 mm bore and a 550 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while freeing up sensor groove access on three sides.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic position sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune the exhaust bleed via a set screw, softening the mechanical impact as the piston decelerates near the end caps.

Where the Airtac SE32 Standard Cylinder SE32X550S Is Used
Lab Sample Dispenser
Drives a 550 mm carriage to route test vials into analysis bays, using the 402 N extend force to overcome guide friction while the DMSE sensor confirms vial handoff.
Film Roll Ejector
Pushes depleted shrink-wrap cores out of a winding cradle, relying on the field-adjustable cushion to stop the 32 mm rod smoothly before it strikes the machine guard.
Small Parts Sorter
Actuates a diverter arm across a 550 mm gap to separate lightweight stamped metal components, benefiting from the tie-rod-free profile that mounts flush to the conveyor rail.
Is the Airtac SE32 Standard Cylinder SE32X550S the Right Cylinder?
When sizing this 32 mm bore, consider stepping down to a 20 mm bore if your load requires less energy, or up to a 40 mm bore which provides 628 N of push at 0.5 MPa for heavier resistance. The SE32X550S is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing direct retrofits using existing FA front flange or LB foot mounting hardware without re-drilling the machine bed.
Because this model features a 550 mm stroke, the 12 mm rod and internal bearing face increased bending moments under side loads. For applications spanning this distance, always incorporate an external linear guide to prevent rod deformation and premature seal wear. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold the load if air pressure drops. For position holding, explore a 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 SE32 Standard Cylinder SE32X550S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At 0.7 MPa, the push force is 563 N. The maximum push force is 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE32X550S is dimensionally interchangeable with standard ISO 15552 profile cylinders, meaning it shares identical mounting and port dimensions. You can reuse your existing mounting brackets and PT1/8 port fittings during the retrofit.
