About the Airtac SE50 Standard Cylinder SE50AX185
The AirTAC SE50AX185 is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It features a square extruded aluminum barrel without external tie rods, making the body highly corrosion-resistant and easy to mount flush against machine frames. Equipped with a SUS420J2 stainless steel rod, this variant is engineered specifically for corrosive or washdown environments.
Delivering 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, it operates at speeds of 30-800 mm/s. The 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. This specific SKU does not include a position sensor magnet.

Where the Airtac SE50 Standard Cylinder SE50AX185 Is Used
Flow Wrapper Cutting
Drives the rotary knife on a packaging line, using the 982 N push force and 185 mm stroke to cleanly sever film at high cycling speeds.
Beverage Bottling Rinse
Actuates washdown spray nozzles in a bottling plant, leveraging the SUS420J2 stainless rod to withstand continuous moisture and cleaning chemicals.
Printed Circuit Board Clamping
Secures PCBs during automated soldering, using the adjustable end cushions to gently decelerate the 185 mm stroke and protect delicate components.
Is the Airtac SE50 Standard Cylinder SE50AX185 the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa; if you need less force, step down to the 40 mm bore (628 N push), or step up to the 63 mm bore (1559 N push) for heavier loads. Since this SKU lacks a magnet, you cannot mount AirTAC CMSE or DMSE sensors for position feedback. A plain SE cylinder will drift if air pressure is lost or a valve is centered, so it cannot hold a load unpowered—consider the BSE rod lock series if position holding is required. With a 185 mm stroke, the unsupported load should be guided externally to prevent rod-bearing bending and premature seal wear.
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 SE50AX185 FAQ
At 0.5 MPa, the SE50AX185 provides 982 N push and 825 N pull force. At 0.7 MPa, the push 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.
Yes, the SE50AX185 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders using existing mounting hardware, matching the 50 mm bore, 185 mm stroke, and PT1/4 port.
