About the Airtac SE50 Standard Cylinder SE50AX290
The AirTAC SE50AX290 is a double-acting ISO 15552 profile cylinder engineered with a 50 mm bore and a 290 mm stroke. It provides a robust 982 N push force at 0.5 MPa, making it well-suited for moderate-load automation tasks. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames without protruding hardware.
This specific SKU utilizes a SUS420J2 stainless steel piston rod (code A) for superior resistance to moisture and washdown environments. It features field-adjustable air cushioning at both stroke ends, allowing technicians to tune deceleration via a set screw to soften hard end stops at high cycling speeds. Note that this configuration ships without a magnet, so it cannot host CMSE or DMSE position sensors.

Where the Airtac SE50 Standard Cylinder SE50AX290 Is Used
Flow Wrapper Flap Diversion
Actuates routing gates on stainless food-packaging lines, using the 982 N push force to reliably divert cardboard blanks while the SUS420J2 rod withstands daily washdowns.
Bottling Line Pallet Stop
Cycles at 30-800 mm/s to halt filled crate pallets at 290 mm extension, relying on the adjustable end cushions to absorb kinetic energy without slamming the frame.
Lab Mixer Lid Lifting
Raises and lowers heavy mixer lids in humid laboratory settings, leveraging the corrosion-resistant stainless rod and tie-rod-free extruded profile for tight clearance mounting.
Is the Airtac SE50 Standard Cylinder SE50AX290 the Right Cylinder?
Select this 50 mm bore when an application requires roughly 1000 N of push force at 0.5 MPa. If you need less thrust, stepping down to the 40 mm bore yields 628 N; if your load demands more power, stepping up to the 63 mm bore provides 1559 N. Because this is a standard double-acting cylinder, it cannot hold a load in place if air pressure drops or the valve centers—piston drift will occur, so integrate a BSE rod lock for fail-safe holding. At 290 mm of stroke, the M16x1.5 rod and bearing are subject to bending moments under heavy lateral loads; always support the payload with an external guide rail to prevent premature seal wear. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders using the same 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 SE50AX290 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 reaches 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
This specific SE50AX290 SKU lacks a built-in magnet, so it cannot support AirTAC CMSE or DMSE sensors. Dimensionally, it is an ISO 15552 profile cylinder, making it a drop-in replacement for any standard ISO 15552 cylinder with a 50 mm bore, 290 mm stroke, and PT1/4 port.
