Airtac SE63 Standard Cylinder SE63AX25
The AirTAC SE63 Standard Cylinder SE63AX25 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø63mm bore and 25mm stroke, PT3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SE63 Standard Cylinder SE63AX25
The AirTAC SE63AX25 is a double-acting single-rod ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers a robust 1559 N push force at 0.5 MPa alongside a 1402 N pull force, making it well-suited for high-impact clamping and ejection tasks within a tight 25 mm travel. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames without snagging on adjacent tooling.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (code A) to withstand corrosive environments and washdown procedures. Because this SKU lacks the built-in magnet suffix (-S), it does not support AirTAC CMSE or DMSE electronic position sensors out of the box. Field-adjustable pneumatic cushioning at both end caps allows technicians to fine-tune end-of-stroke deceleration, softening hard mechanical stops during rapid 30-800 mm/s cycling.

Where the Airtac SE63 Standard Cylinder SE63AX25 Is Used
CNC Lathe Chuck Ejection
Uses the 1559 N extend force and 25 mm stroke to rapidly eject finished metal rings from a lathe chuck, where the SUS420J2 rod resists cutting fluid splash.
Form-Fill-Seal Cut-off
Drives the mechanical knife assembly on a vertical form-fill-seal packaging line, relying on the adjustable end-cushions to halt the blade precisely without shock.
Injection Mold Parting
Actuates a secondary side-core pull on an injection mold base, where the compact tie-rod-less profile fits within tight mold platen clearances.
Is the Airtac SE63 Standard Cylinder SE63AX25 the Right Cylinder?
When sizing this actuator, evaluate your force margins in both directions. If 1559 N of push at 0.5 MPa is excessive for your fixture, stepping down to the 50 mm bore reduces the output to 982 N while retaining the same ISO 15552 mounting footprint. Conversely, heavily loaded short-stroke presses might require the 80 mm bore, which elevates the push force to 2513 N. Remember that a standard SE cylinder relies on live air pressure to maintain its position; if air is lost or the valve centers, the piston will drift and cannot hold a load. For positive holding without sustained pressure, specify the BSE rod-lock variant instead. To retrofit this into an existing ISO 15552 cell, confirm the 63 mm bore, 25 mm stroke, PT3/8 port, and your required mounting accessory (such as an FA front flange or LB foot).
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 SE63AX25 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 operated at the 1.0 MPa pressure limit.
This specific SKU lacks the -S magnet, so it cannot host CMSE or DMSE sensors without modification. Dimensionally, it serves as a direct replacement for any standard ISO 15552 / VDMA 24562 profile cylinder, sharing identical mounting interface dimensions and a PT3/8 port.
