Airtac SE32 Standard Cylinder SE32X70
The AirTAC Airtac SE32 Standard Cylinder SE32X70 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE32 Standard Cylinder SE32X70
The AirTAC SE32X70 is a double-acting, single-rod ISO 15552 profile cylinder delivering 402 N push force at 0.5 MPa. It features a 32 mm bore, 70 mm stroke, and a PT1/8 port. The extruded aluminum square barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This unit relies on field-adjustable air cushioning at both ends to soften hard end stops, giving technicians a screw to tune deceleration for the 30-800 mm/s speed range. This specific SKU lacks the -S magnet, so it does not support CMSE or DMSE position sensing out of the box.

Where the Airtac SE32 Standard Cylinder SE32X70 Is Used
PCB Router Gating
Actuates a small pneumatic gate on a PCB depaneling router, using the 402 N push force to divert cut panels into reject bins.
Lab Dispenser Indexing
Drives a 70 mm stroke indexing arm on a clinical reagent dispenser, benefiting from the flush profile barrel to fit tight lab enclosures.
Carton Flap Folding
Folds minor flaps on a small-format carton erector, where the 345 N retract force easily handles lightweight paperboard.
Is the Airtac SE32 Standard Cylinder SE32X70 the Right Cylinder?
Generating 402 N push at 0.5 MPa, this 32 mm bore is the smallest standard SE size. If your assembly requires less force, there is no smaller SE option, but stepping up to the 40 mm bore raises push output to 628 N. Because this is a standard 70 mm stroke, it drops directly into existing ISO 15552 mounting interfaces using basic or LB foot hardware with a PT1/8 port.
Remember that a plain SE cylinder does not hold its position when air is lost or a valve centers; the piston drifts. The adjustable cushion only decelerates the piston near stroke end and acts purely as a speed brake, never a load lock.
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 SE32X70 FAQ
At 0.5 MPa, the SE32X70 provides 402 N push and 345 N pull. At 0.7 MPa, push increases to 563 N. The maximum push force is 82 kgf at 1.0 MPa operating pressure.
Yes, the SE32X70 is dimensionally interchangeable per ISO 15552 standards. Its standardized mounting interface allows it to serve as a drop-in replacement for other ISO 15552 profile cylinders without changing mounting hardware.
