About the Airtac SE63 Standard Cylinder SE63AX125S
The AirTAC SE63AX125S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding 63 mm bore tasks, delivering 1559 N of push force at 0.5 MPa. The unit features a square extruded aluminum barrel without external tie rods, yielding a compact footprint that resists corrosion and mounts flush against machine frames. Equipped with a built-in magnet (code S), it seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (code A), making it highly suitable for corrosive or washdown environments where a standard carbon steel rod would degrade. Field-adjustable pneumatic cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a setscrew, softening hard impacts during high-speed 30-800 mm/s cycling. The PT3/8 port and M16x1.5 rod thread provide robust connection points for this 125 mm stroke actuator.

Where the Airtac SE63 Standard Cylinder SE63AX125S Is Used
Pouch Forming Sealer
Drives the sealing jaw on a vertical form-fill-seal machine, using the 125 mm stroke to close and crimp packaging film with 1559 N of thrust in a washdown environment.
Bottle Divert Gate
Actuates a diverter arm on a bottling conveyor, relying on the SUS420J2 stainless rod to withstand daily chemical washdowns while shifting product lanes at 30-800 mm/s.
CNC Lathe Unloader
Pushes finished metal parts out of a CNC turning center, utilizing the built-in magnet and a DMSE sensor to confirm part ejection before the chuck reopens.
Is the Airtac SE63 Standard Cylinder SE63AX125S the Right Cylinder?
Selecting this 63 mm bore actuator makes sense when a 50 mm cylinder (offering 982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (providing 2513 N push) would be physically oversized. The 125 mm stroke provides ample extension for mid-range positioning tasks. Because this is a double-acting cylinder, it relies on continuous live air pressure to maintain its position; if air is lost or the valve centers, the piston will drift, so a BSE rod lock variant is required for fail-safe holding.
The SUS420J2 rod material is specifically chosen here to endure moisture, cleaning chemicals, or mild corrosive exposure. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders, sharing identical mounting interface dimensions and hardware. At 125 mm stroke, the side load on the M16x1.5 rod bearing remains moderate, though any heavily offset load should still utilize an external guide rail to prevent premature seal wear.
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 SE63AX125S 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. The maximum allowable push force is 318 kgf when operating at the 1.0 MPa pressure limit.
No, the SE63AX125S is a standard double-acting cylinder and cannot hold position unpowered; the piston will drift if air is lost. The adjustable air cushion only decelerates the piston near the stroke ends and does not act as a brake. For secure load holding, consider the BSE rod lock variant or an external pilot-operated check valve.
