About the Airtac SE50 Standard Cylinder SE50AX650S
The AirTAC SE50AX650S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 650 mm stroke. It generates 982 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod (code A) specifically selected for corrosive or washdown environments.
This extruded aluminum body omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. Equipped with a built-in magnet (code S), the cylinder interfaces directly with AirTAC CMSE reed and DMSE electronic sensors to provide reliable end-of-stroke positioning feedback.

Where the Airtac SE50 Standard Cylinder SE50AX650S Is Used
Bottling Line Diverter
Routes plastic containers between filling lanes using the 982 N push force and 650 mm travel, while the SUS420J2 rod withstands routine washdown chemicals.
Corrugated Box Pusher
Transfers flattened cardboard blanks across a packaging station, utilizing the full 650 mm stroke to clear the conveyor path for the next cycle.
Lab Sample Handler
Moves test tube racks into an inspection chamber, relying on the built-in magnet and DMSE electronic sensors to confirm full extension in humid conditions.
Is the Airtac SE50 Standard Cylinder SE50AX650S the Right Cylinder?
This 50 mm bore yields 982 N push at 0.5 MPa. If your application requires less force, the 40 mm neighbor provides 628 N; stepping up to the 63 mm bore increases output to 1559 N. As a standard ISO 15552 profile cylinder, it serves as a direct dimensional replacement for equivalent 50x650 units, utilizing the PT1/4 port and standard mounting accessories. Note that a plain SE cylinder will drift if air pressure is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking the load.
Because the 650 mm stroke creates an extended lever arm, side loading can induce severe bending stress on the Ø20 mm rod and its bearing. An external guide mechanism should be installed to prevent premature seal wear and rod deformation.
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 SE50AX650S FAQ
At 0.5 MPa, the SE50AX650S provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The cylinder reaches a maximum push force of 200 kgf at its 1.0 MPa operating pressure limit.
No, a standard SE cylinder cannot hold a load without live air pressure. The field-adjustable air cushion at both ends only decelerates the piston near the end of stroke; it does not function as a brake. If your application requires position holding during pressure loss, you must use a BSE rod lock variant or an external pilot-operated check valve.
