About the Airtac SE63 Standard Cylinder SE63X425
The AirTAC SE63X425 is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 1559 N push force at 0.5 MPa and a maximum thrust of 318 kgf at 1.0 MPa. Its square extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while keeping the standardized ISO 15552 footprint for seamless retrofitting.
This 63 mm bore unit travels a 425 mm stroke through a PT3/8 port and a Ø20 mm hard-chrome rod. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycling. Note that this specific SKU lacks a built-in magnet, meaning it will not interface with CMSE or DMSE position sensors without modification.

Where the Airtac SE63 Standard Cylinder SE63X425 Is Used
Pallet Transfer Line Diverter
Actuates a 425 mm routing gate on a 50 mm conveyor belt, using the 1559 N push force to reliably pivot heavy timber pallets onto secondary packaging tracks.
CNC Lathe Bar Feeder
Provides a steady 425 mm extension to push hex steel stock through a spinning collet, relying on the adjustable end-cushions to prevent mechanical shock at high traverse speeds.
Automotive Panel Press Ejector
Kicks stamped door panels out of a hydraulic press bed, utilizing the 318 kgf maximum thrust to clear heavy steel blanks before the upper die returns.
Is the Airtac SE63 Standard Cylinder SE63X425 the Right Cylinder?
When sizing this actuator, consider stepping down to the 50 mm bore if your load requires less energy, as it provides 982 N of push at 0.5 MPa. Conversely, if your application demands greater thrust, the 80 mm bore offers 2513 N at 0.5 MPa. Because this is a 425 mm stroke, the unsupported rod length introduces a bending moment on the rod-bearing; an external guide rail is highly recommended to prevent side-load wear and premature seal failure.
As a standard double-acting cylinder, the SE63X425 cannot hold a load or maintain its position if air pressure is lost or the directional valve is centered, as the piston will drift. If your workflow requires mid-stroke holding without live pressure, you must integrate an external pilot-operated check valve or transition to 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 SE63X425 FAQ
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum of 318 kgf at 1.0 MPa. It uses a PT3/8 port, a Ø20 mm rod, and operates at speeds of 30-800 mm/s.
Yes, the SE63X425 shares the exact ISO 15552 mounting interface, making it a drop-in replacement for other ISO 15552 profile cylinders. Its extruded barrel omits external tie rods, simplifying flush mounting and reducing trapped debris in clean environments.
