About the Airtac SE50 Standard Cylinder SE50X622S
The AirTAC SE50X622S is a double-acting single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 622 mm stroke. Because 622 mm exceeds the standard 1200 mm maximum for this bore, it is supplied as a non-standard, made-to-order unit. It delivers a robust 982 N push force at 0.5 MPa and pulls with 825 N, making it well-suited for long-travel positioning tasks.
This actuator utilizes a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush against frames. The integrated -S magnet enables direct fitment of CMSE reed and DMSE electronic sensors in the side grooves for precise end-of-stroke detection. Field-adjustable pneumatic cushioning at both ends allows you to tune end-stop deceleration for heavy loads traveling this long distance.

Where the Airtac SE50 Standard Cylinder SE50X622S Is Used
Pallet Conveyor Transfer
Uses the 982 N push force and 622 mm stroke to push heavy wooden pallets smoothly from a high-speed packaging line onto a secondary roller conveyor.
Lab Sample Indexing
Leverages the built-in magnet with DMSE electronic sensors to precisely index fluid sample racks across a 622 mm travel distance inside automated diagnostic analyzers.
Carton Erector Arm
Deploys the long 622 mm stroke and adjustable end cushions to gently extend and fold cardboard flaps on large format packaging machinery without crushing the board.
Is the Airtac SE50 Standard Cylinder SE50X622S the Right Cylinder?
At 0.5 MPa, this 50 mm bore cylinder outputs 982 N of push force. If your application requires less thrust, stepping down to a 40 mm bore reduces the output to 628 N, while moving up to a 63 mm bore increases the push force to 1559 N. Because the SE50X622S uses a custom 622 mm stroke, it is ordered to exact dimensions rather than pulled from standard stock.
When replacing an existing actuator, verify the PT1/4 port, 50 mm bore, 622 mm stroke, and required mounting hardware. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for straightforward retrofitting. Note that this plain double-acting cylinder does not hold its load when air is exhausted or the valve is centered; the piston will drift, so a BSE rod lock or external pilot-operated check valve is required for position holding. Furthermore, at 622 mm, the unsupported rod length is substantial; an external guide is strongly recommended to prevent rod-bearing bending under side loads.
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 SE50 Standard Cylinder SE50X622S FAQ
The 50 mm bore provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push of 200 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes. The SE50X622S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 50 mm bore, 622 mm stroke, PT1/4 port, and mounting interface.
