About the Airtac SE63 Standard Cylinder SE63AX50S
The AirTAC SE63AX50S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 63 mm bore and 50 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for moderate-to-heavy industrial actuation. Equipped with a SUS420J2 stainless steel rod (code A), this variant is purpose-built to withstand corrosive environments and washdown procedures without compromising mechanical strength.
The extruded aluminum barrel features a square profile completely free of external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting surface corrosion. Integrated sensor grooves on three sides of the body allow flexible placement of CMSE reed or DMSE electronic switches, leveraging the built-in S magnet for precise end-of-stroke detection. Furthermore, the field-adjustable pneumatic cushioning at both stroke ends can be tuned via a setscrew to smoothly decelerate the piston, eliminating harsh mechanical impacts during high-speed cycling.

Where the Airtac SE63 Standard Cylinder SE63AX50S Is Used
Flow Wrapper Sealing
Drives the cross-sealing jaw on continuous flow wrappers, utilizing the 1559 N push force to cleanly cut and seal packaging film at high cycle rates.
Lab Washdown Station
Actuates spray nozzles and clamps in pharmaceutical washdown stations, where the SUS420J2 stainless steel rod prevents corrosion from harsh cleaning chemicals.
CNC Pallet Clamp
Secures machining pallets on multi-station rotary tables, using the DMSE sensor magnet to confirm clamp engagement before the spindle starts.
Is the Airtac SE63 Standard Cylinder SE63AX50S the Right Cylinder?
When sizing this actuator, consider stepping down to the 50 mm bore if your load requires less force, as it provides a 982 N push at 0.5 MPa. Conversely, if your application demands greater thrust, stepping up to the 80 mm bore yields a 2513 N push at 0.5 MPa. Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure is lost or the valve is centered; for position-holding safety, explore the BSE rod-lock variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a direct dimensional replacement for other ISO 15552 cylinders, utilizing identical mounting hardware and a PT3/8 port. The 50 mm stroke keeps the unsupported rod length short, meaning side-load stress on the M16x1.5 rod thread and bearing is minimal, though external guides remain best practice for offset loads.
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 SE63AX50S FAQ
The SE63AX50S features a 63 mm bore and a PT3/8 port. It generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. At 0.7 MPa, the push force is 2182 N, and the absolute maximum push force is 318 kgf at 1.0 MPa.
Yes, the SE63AX50S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting interface and hole patterns as other ISO 15552 profile cylinders. You can use your existing mounting brackets and drop it directly into the same footprint.
