About the Airtac SE50 Standard Cylinder SE50AX300S
The AirTAC SE50AX300S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 300 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a PT1/4 port and a 20 mm piston rod. The rod is constructed from SUS420J2 stainless steel (code A), making the unit highly suitable for corrosive environments or washdown duty where standard carbon steel would fail.
This model includes a built-in magnet (code S) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors. The extruded aluminum barrel lacks external tie rods, yielding a compact footprint that mounts flush against machine frames. Furthermore, the field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration, effectively softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX300S Is Used
Bottling Line Diverter
Utilizes the 982 N push force and SUS420J2 stainless rod to reliably divert plastic bottles on a washdown-grade packaging conveyor.
Stainless Steel Press Brake
Employs the 300 mm stroke to position upper tooling on a small metal forming press, relying on adjustable cushions to soften end stops.
Lab Sample Ejector
Leverages the DMSE electronic sensor compatibility and compact tie-rod-free profile to eject tested samples from tight analytical machinery.
Is the Airtac SE50 Standard Cylinder SE50AX300S the Right Cylinder?
Selecting the SE50AX300S is appropriate when your application requires roughly 1000 N of push force at 0.5 MPa. If you need less force, the 40 mm bore variant provides 628 N of push, while stepping up to the 63 mm bore yields 1559 N. Because this unit features a 300 mm stroke, the extended piston rod is subject to bending moments under side loads; always use an external guide rail to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders, matching standard mounting accessories like FA front flanges or LB foot brackets. Note that while the adjustable cushions decelerate the piston near stroke end, this standard cylinder does not hold a load if air pressure is lost; for position holding, consider the BSE rod lock variant.
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 SE50AX300S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
