About the Airtac SE63 Standard Cylinder SE63AX20
The AirTAC SE63AX20 is a double-acting single-rod ISO 15552 profile cylinder delivering 1559 N of push force at 0.5 MPa. It features a 20 mm stroke and a 63 mm bore, utilizing a PT3/8 port. The extruded aluminum barrel lacks external tie rods, yielding a compact footprint that mounts flush against frames and resists corrosion.
This specific SKU is built with a SUS420J2 stainless steel rod (code A) for corrosive and washdown environments. It lacks a built-in magnet, meaning it is not wired for CMSE or DMSE position sensing out of the box. The field-adjustable air cushion at both ends allows you to tune end-of-stroke deceleration via a screw, preventing hard impacts during rapid 30-800 mm/s cycles.

Where the Airtac SE63 Standard Cylinder SE63AX20 Is Used
Flow Wrapper End-Seal Jaw
Provides the 1559 N push at 0.5 MPa required to close sealing jaws on continuous flow wrappers, withstanding washdowns via its SUS420J2 stainless rod.
CNC Lathe Bar Feeder Gate
Actuates a short 20 mm stroke gate to release bar stock into the spindle, benefiting from the compact tie-rod-free profile that saves valuable machine real estate.
Beverage Lab Test Fixture
Clamps sample bottles during pressure testing, using the adjustable pneumatic cushion to soften end stops and prevent glass fracture during retraction.
Is the Airtac SE63 Standard Cylinder SE63AX20 the Right Cylinder?
If 1559 N push at 0.5 MPa is too much force, step down to the 50 mm bore (982 N push). If you need more thrust, step up to the 80 mm bore (2513 N push). Because this is a short 20 mm stroke, side-load bending on the rod bearing is minimal, though long unsupported strokes still require an external guide. Remember that a plain SE cylinder does not hold loads when air is lost; if your application needs fail-safe holding, use a BSE rod lock. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for direct retrofits.
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 SE63AX20 FAQ
At 0.5 MPa, it provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, push force is 2182 N, with a maximum push of 318 kgf at 1.0 MPa. It features a 63 mm bore, 20 mm stroke, PT3/8 port, and a SUS420J2 stainless steel rod.
No, this specific SKU lacks the built-in magnet (no -S code) required for AirTAC CMSE reed or DMSE electronic sensors. If you need position feedback, select an SE63X20S model instead.
