About the Airtac SE63 Standard Cylinder SE63AX425S
The AirTAC SE63AX425S is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding 63 mm bore applications. It delivers a robust 1559 N push force at 0.5 MPa and 2182 N at 0.7 MPa, utilizing a 20 mm stainless steel piston rod. The 425 mm stroke on this unit is a non-standard made-to-order length, expanding your machine design envelope beyond the 1500 mm standard catalog maximum.
Because this configuration carries the A rod code, it features a SUS420J2 stainless steel rod optimized for corrosive and washdown environments. The extruded aluminum barrel lacks external tie rods, yielding a compact, flush-mounting footprint that resists grime buildup. Equipped with an S magnet, the body seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.

Where the Airtac SE63 Standard Cylinder SE63AX425S Is Used
Pharmaceutical Washdown Gate
Actuates a divert valve in a pill-coating line, using the SUS420J2 stainless rod to withstand daily chemical washdowns while providing 1559 N push at 0.5 MPa.
CNC Lathe Bar Feeder
Pushes raw bar stock into a collet chuck over a 425 mm stroke, relying on the built-in S magnet and DMSE electronic sensors to confirm material staging.
Palletizing Robot Arm
Extends a vacuum gripper assembly to lift corrugated cardboard boxes, utilizing the adjustable air cushion to halt the 2182 N @0.7 MPa thrust smoothly.
Is the Airtac SE63 Standard Cylinder SE63AX425S the Right Cylinder?
This 63 mm bore provides 1559 N push at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 982 N push, while moving up to the 80 mm bore provides 2513 N. As a standard double-acting cylinder, it does not hold a load if air pressure drops; for position-holding safety, consider the BSE rod-lock variant or an external pilot-operated check valve. The 425 mm stroke exceeds the 1500 mm standard maximum, making it a special order.
For a 425 mm stroke, the unsupported rod length increases bending stress on the rod bearing under lateral loads. To prevent premature seal wear and scoring, implement an external guide rail to absorb radial forces. The field-adjustable air cushion at both ends uses a needle screw to tune end-of-stroke deceleration, softening hard mechanical impacts at operating speeds up to 800 mm/s.
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 SE63AX425S 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 is 2182 N. The maximum push force is 318 kgf at 1.0 MPa.
