About the Airtac SE63 Standard Cylinder SE63AX70
The AirTAC SE63AX70 is a double-acting single-rod ISO 15552 profile cylinder engineered for a 63 mm bore and a 70 mm stroke. It supplies a robust 1559 N push force at 0.5 MPa, utilizing a PT3/8 port and a 20 mm rod with an M16x1.5 thread. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
This specific SKU features a SUS420J2 stainless steel rod (code A) tailored for corrosive or washdown environments. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. Note that this configuration ships without a sensor magnet, so position detection is not supported on this unit.

Where the Airtac SE63 Standard Cylinder SE63AX70 Is Used
Carton Flap Folding
Drives the mechanical arms on corrugated box forming machinery, using the 70 mm stroke and 1559 N push to cleanly fold heavy cardboard flaps during high-speed packaging runs.
Lab Washdown Station
Actuates rinse nozzles in pharmaceutical glassware cleaning lines, where the SUS420J2 stainless rod provides necessary resistance to repeated chemical and water exposure.
CNC Lathe Door Glide
Shifts the sliding safety enclosure on a CNC turning center, relying on the smooth 30-800 mm/s speed range and adjustable cushions to prevent jarring door slams.
Is the Airtac SE63 Standard Cylinder SE63AX70 the Right Cylinder?
Selecting this 63 mm bore makes sense when your application requires the 1559 N push at 0.5 MPa that this model provides. If your load is lighter, stepping down to the 50 mm bore drops the push to 982 N, saving air volume; conversely, heavy loads might require stepping up to the 80 mm bore, which raises the push to 2513 N. Because this cylinder uses a PT3/8 port and standard ISO 15552 mounting dimensions, it serves as a direct dimensional replacement for competing ISO 15552 profile cylinders without requiring custom brackets.
Keep in mind that a plain SE cylinder drifts when air pressure is lost or the valve centers, as the adjustable cushion only decelerates the piston near stroke end and does not function as a locking brake. If your process demands fail-safe load holding, pair this unit with an external pilot-operated check valve or explore the AirTAC 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 SE63 Standard Cylinder SE63AX70 FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and cycles at speeds between 30-800 mm/s.
This specific SE63AX70 SKU lacks a built-in magnet, so it cannot host CMSE or DMSE position sensors without modifying the piston. Dimensionally, it adheres strictly to the ISO 15552 profile standard, meaning it serves as a direct replacement for any equivalent 63 mm ISO 15552 profile cylinder using standard mounting accessories.
