About the Airtac SE50 Standard Cylinder SE50AX300
The AirTAC SE50AX300 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. Featuring a 50 mm bore and 300 mm stroke, it operates at speeds from 30-800 mm/s via a PT1/4 port. The extruded aluminum barrel eliminates external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration.
This specific SKU is configured with a SUS420J2 stainless steel rod (code A) for superior resistance to moisture and washdown chemicals. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. Note that this unit lacks a built-in magnet, so it is not ready for CMSE or DMSE position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50AX300 Is Used
Flow Wrapper Chain Transfer
Drives the pusher lug chain on a horizontal flow wrapper, utilizing the 982 N push force at 0.5 MPa to index film rolls precisely while the SUS420J2 rod shrugs off washdown moisture.
Bottling Line Diverter Gate
Actuates a pneumatic sorting flap on a high-speed bottling conveyor, where the 300 mm stroke provides ample travel to redirect glass containers between packaging lanes.
Lab Mixer Lid Lift
Raises the hinged stainless-steel lid on a pharmaceutical ribbon mixer, relying on the adjustable end cushions to soften the 300 mm upward stroke and protect the glass observation window.
Is the Airtac SE50 Standard Cylinder SE50AX300 the Right Cylinder?
When sizing this actuator, evaluate your force margins: stepping down to a 40 mm bore drops the 0.5 MPa push output to 628 N, while moving up to a 63 mm bore increases it to 1559 N. Because this is a single-rod cylinder, it cannot hold a load if air pressure is lost or the valve is centered—the piston will drift. For position-holding safety, consider the BSE rod-lock variant or an external pilot-operated check valve.
At a 300 mm stroke, the unsupported rod length increases bending moments on the rod bearing under side loads; always use an external guide to prevent premature seal wear. As a true ISO 15552 cylinder, this model offers drop-in dimensional interchangeability with other ISO 15552 profile cylinders, matching the 50 mm bore, 300 mm stroke, PT1/4 port, and standard mounting accessories.
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 SE50AX300 FAQ
The SE50AX300 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 capacity of 200 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 standards, allowing drop-in replacement for other ISO 15552 profile cylinders using the same mounting hardware. This specific SKU does not include a built-in magnet (-S), so it cannot directly interface with CMSE or DMSE position sensors.
