About the Airtac SE32 Standard Cylinder SE32X550
The AirTAC SE32X550 is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering a 402 N push at 0.5 MPa. Its extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
This 32 mm bore unit travels 550 mm and relies on a field-adjustable air cushion at both ends to decelerate the piston smoothly before end-of-stroke impact. Because this specific SKU lacks the -S magnet suffix, it is not equipped for AirTAC CMSE or DMSE electronic position sensing out of the box.

Where the Airtac SE32 Standard Cylinder SE32X550 Is Used
Sorting Diverter Gate
Actuates a low-profile flap on a packaging sorting line, using its 402 N push to deflect light cardboard cartons at high cycling speeds.
Small Part Ejector
Pushes machined aluminum brackets out of a CNC machining center, utilizing the 550 mm stroke to clear the work envelope entirely.
Lab Sample Dispenser
Moves a test tube rack along a diagnostic analyzer, benefiting from the smooth adjustable cushioning to prevent liquid spillage at stroke end.
Is the Airtac SE32 Standard Cylinder SE32X550 the Right Cylinder?
This 32 mm bore generates 402 N of push force at 0.5 MPa. If your application requires less energy, the next size down does not exist in the ISO 15552 standard, but stepping up to a 40 mm bore provides a 628 N push. As a drop-in replacement, match the 32 mm bore, 550 mm stroke, PT1/8 port, and your required mounting hardware like an FA front flange or LB foot. Since the 550 mm stroke is substantial for a 12 mm rod, the unsupported piston is highly susceptible to side-load bending; incorporating an external guide rail prevents rod-bearing wear and jamming. Note that an SE cylinder will drift if air pressure is lost—the cushion only softens the end stop and does not lock the load.
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 SE32X550 FAQ
At 0.5 MPa, the SE32X550 provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push increases to 563 N. The maximum push force is 82 kgf when operated at the 1.0 MPa pressure limit.
Yes, the SE32X550 is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other 32 mm bore, 550 mm stroke ISO 15552 profile cylinders, provided your porting and mounting accessories match.
