About the Airtac SE63 Standard Cylinder SE63AX550
The AirTAC SE63AX550 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 550 mm stroke. It operates efficiently at 30-800 mm/s, generating a substantial 1559 N push force at 0.5 MPa and a maximum output of 318 kgf at 1.0 MPa. The integrated SUS420J2 stainless steel rod provides essential corrosion resistance for demanding washdown environments.
Unlike traditional round-body or tie-rod actuators, this unit features a square extruded aluminum barrel that mounts flush while exposing sensor grooves on three sides. It also incorporates field-adjustable air cushioning at both ends, allowing technicians to tune the 36 mm cushion length via a set screw to soften hard end-stops at high velocities. Note this specific SKU lacks a built-in magnet, meaning it is not wired for CMSE or DMSE position sensing out of the box.

Where the Airtac SE63 Standard Cylinder SE63AX550 Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spindle with 1559 N at 0.5 MPa, while the SUS420J2 rod withstands coolant splashing.
Bottling Line Diverter
Handles the 550 mm stroke to route plastic containers between packaging lanes without tie-rod protrusions catching passing traffic.
Food-Grade Washdown Actuator
Executes automated gate transitions in a meat processing facility, relying on the stainless steel rod material to survive daily high-pressure chemical washdowns.
Is the Airtac SE63 Standard Cylinder SE63AX550 the Right Cylinder?
If your application requires slightly less force, the adjacent SE50 bore provides 982 N of push at 0.5 MPa, whereas stepping up to the SE80 yields 2513 N for heavier loads. Because this is a standard 550 mm stroke within the 63 mm bore's 1500 mm maximum, it is readily available. Remember that a plain SE cylinder will drift if air pressure is lost or the valve is centered; for position holding, consider the BSE rod lock variant. Furthermore, at 550 mm of unsupported extension, the 20 mm rod and M16x1.5 thread face side-load bending moments, dictating the use of an external guide rail to prevent premature bearing wear. As a true ISO 15552 profile cylinder, it serves as a direct replacement sharing standard mounting interface dimensions with other ISO 15552 cylinders.
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.
