About the Airtac SE63 Standard Cylinder SE63AX425
The AirTAC SE63AX425 is a double-acting single-rod ISO 15552 profile cylinder engineered for a 63 mm bore and a 425 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, scaling to 2182 N at 0.7 MPa, making it well-suited for demanding industrial positioning tasks.
This variant features a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance in washdown or humid settings. The extruded aluminum barrel eliminates external tie rods for a clean, compact profile, while the field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration for high-speed cycles.

Where the Airtac SE63 Standard Cylinder SE63AX425 Is Used
Bottling Line Diverters
Actuates routing gates on beverage lines, using the 1559 N push force to reliably shift heavy crate traffic while the SUS420J2 rod withstands daily washdowns.
Corrugated Box Flap Folders
Drives mechanical arms to fold heavy cardboard flaps over a 425 mm span, benefiting from the adjustable end cushions to prevent harsh slamming at high cycle rates.
Pulp and Paper Testing Equipment
Provides consistent horizontal pressure for material sampling fixtures, where the corrosion-resistant stainless rod ensures longevity in high-humidity laboratory environments.
Is the Airtac SE63 Standard Cylinder SE63AX425 the Right Cylinder?
If your application requires less force, stepping down to the 50 mm bore yields 982 N of push at 0.5 MPa, whereas stepping up to the 80 mm bore provides 2513 N. Because this 425 mm stroke exceeds 300 mm, the unsupported piston rod is susceptible to bending under lateral loads; always incorporate an external guide rail to prevent rod-bearing damage. As a standard ISO 15552 profile cylinder, it serves as a direct dimensional replacement for comparable 63 mm bore cylinders, utilizing the PT3/8 port and M16x1.5 rod thread. Note that this SKU lacks a position-sensing magnet, so it cannot host CMSE or DMSE switches without modification.
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 SE63AX425 FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force reaches 2182 N. The maximum push force is 318 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No, the SE63AX425 is a standard double-acting cylinder and will drift if air is exhausted or valve pressure is lost. The adjustable air cushions at both ends only decelerate the piston near the stroke ends; they do not function as a locking mechanism. For positive holding, an external rod lock like the BSE series is required.
