About the Airtac SE63 Standard Cylinder SE63AX300
The AirTAC SE63AX300 is a double-acting ISO 15552 profile cylinder engineered for a 63 mm bore and 300 mm stroke. It generates 1559 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod, making it highly suitable for corrosive or washdown environments where a standard carbon steel piston would fail prematurely.
The extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush and resists debris buildup. Field-adjustable air cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, protecting the mechanism during high-speed 30-800 mm/s cycling. Note this SKU lacks a position-sensing magnet.

Where the Airtac SE63 Standard Cylinder SE63AX300 Is Used
Bottling Line Capper
Drives a 300 mm stroke capping head on a beverage line, where the SUS420J2 rod withstands daily caustic washdowns while delivering 1559 N push to seal containers.
Pallet Film Dispenser
Actuates a wrapping arm on a stretch film machine, using its 63 mm bore force to maintain tension and its tie-rod-free profile to avoid snagging packaging materials.
CNC Tool Changer
Indexes a tool carousel 300 mm outward, relying on the field-adjustable cushioning to soften the hard end stops during rapid 30-800 mm/s positioning.
Is the Airtac SE63 Standard Cylinder SE63AX300 the Right Cylinder?
This 63 mm bore provides 1559 N push at 0.5 MPa. If your application requires less force, the 50 mm bore offers 982 N push, while stepping up to the 80 mm bore yields 2513 N push for heavier loads. Because the 300 mm stroke creates extended leverage, an external guide is recommended to prevent rod-bearing bending under side loads.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement sharing the standard PT3/8 port, M16x1.5 rod thread, and standardized mounting accessories. Remember that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device, so loads will drift if air pressure is lost.
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 SE63AX300 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 is 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, matching standard PT3/8 ports and mounting footprints. However, it cannot hold a load if air is lost; the adjustable cushion only decelerates the piston near stroke end and does not function as a brake. For position holding, consider a BSE rod lock variant.
