About the Airtac SE50 Standard Cylinder SE50X75SN
The AirTAC SE50X75SN is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa over a 75 mm stroke. Because it uses an extruded aluminum barrel without external tie rods, it offers a flush, corrosion-resistant exterior that mounts cleanly into confined machinery spaces while maintaining the standardized ISO 15552 footprint.
This specific configuration includes an NBR seal for reliable pneumatic operation and a built-in magnet (S) for non-contact position sensing. The magnet is fully compatible with AirTAC CMSE reed and DMSE electronic switches, which drop directly into the sensor grooves on three sides of the body, giving you flexible mounting angles for end-of-stroke verification.

Where the Airtac SE50 Standard Cylinder SE50X75SN Is Used
Carton Erector Flaps
Drives the short 75 mm stroke to fold packaging flaps on high-speed carton erectors, utilizing the 982 N push force to crease heavy cardboard reliably.
CNC Lathe Door Glide
Actuates the sliding safety door on a CNC lathe, where the compact no-tie-rod profile prevents debris buildup and the CMSE sensor confirms door closure.
Stamping Pin Ejection
Ejects small stamped metal pins from a die plate, using the 825 N retract pull force to extract parts quickly within a 30-800 mm/s speed range.
Is the Airtac SE50 Standard Cylinder SE50X75SN the Right Cylinder?
Selecting this 50 mm bore is ideal when you need 982 N of push at 0.5 MPa. If your load is lighter, stepping down to the 40 mm bore yields 628 N, while stepping up to the 63 mm bore provides 1559 N for heavier actuation. At 75 mm, the stroke is short enough that rod-bearing side loads remain minimal, but remember that a plain SE cylinder drifts when air is lost or the valve is centered; for fail-safe load holding, you need a BSE rod lock variant or an external pilot-operated check valve.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders. When ordering, confirm you need the PT1/4 port, the default basic mounting style, and the NBR seal for your operating temperature range.
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 SE50X75SN 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 increases to 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the plain SE50X75SN does not hold its position when air is lost or exhausted; the piston will drift. Additionally, the field-adjustable air cushion at both ends only decelerates the piston near the stroke end and does not act as a brake. For true load holding, use a BSE rod lock variant or an external locking mechanism.
