Airtac SE50 Standard Cylinder SE50AX375S
The AirTAC Airtac SE50 Standard Cylinder SE50AX375S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 375mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50AX375S
The AirTAC SE50AX375S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 375 mm stroke. It delivers a 982 N push force at 0.5 MPa and features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance in washdown or chemically aggressive settings. Because this 375 mm stroke exceeds the standard 1200 mm maximum for the 50 mm bore, it is supplied as a non-standard, made-to-order unit.
The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that simplifies sensor placement along the three integrated sensing grooves. An integrated magnet (-S) supports CMSE reed and DMSE electronic position switches, while the field-adjustable air cushioning at both ends lets you precisely tune end-of-stroke deceleration to protect payloads.

Where the Airtac SE50 Standard Cylinder SE50AX375S Is Used
Bottling Line Diverter
Uses the 982 N push force and SUS420J2 stainless rod to reliably pivot diverting gates on a washdown beverage bottling line without rusting.
Pallet Transfer Rejector
Leverages the 375 mm stroke to push misaligned pallets off a transfer conveyor, absorbing end-of-stroke impact with adjustable air cushions.
Forming Press Ejector
Employs the 30 mm cushion length to smoothly eject formed cardboard blanks from a packaging press, preventing tearing during high-speed retraction.
Is the Airtac SE50 Standard Cylinder SE50AX375S the Right Cylinder?
If you need to adjust thrust, the SE40 bore steps down to 628 N push at 0.5 MPa, while the SE63 bore steps up to 1559 N. As a true ISO 15552 cylinder, this model serves as a drop-in dimensional replacement for any standard 50 mm bore, 375 mm stroke ISO 15552 cylinder, matching the PT1/4 port and M16x1.5 rod thread. It includes the -S magnet for CMSE/DMSE sensors and the A-code stainless steel rod.
Because the 375 mm stroke is non-standard and relatively long, an unsupported piston rod is susceptible to bending under lateral loads; always use an external guide rail to prevent side-load damage to the rod bearing. Note that the adjustable air cushion only decelerates the piston near stroke end and does not hold the load—if air pressure is lost, the cylinder drifts. For position holding, use a BSE rod lock or external pilot-operated check valve.
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 SE50AX375S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke end and is not a locking mechanism. If you need to hold a load without live air pressure, you must use an AirTAC BSE rod lock cylinder or an external pilot-operated check valve.
