About the Airtac SE50 Standard Cylinder SE50BX290SFTC
The AirTAC SE50BX290SFTC is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding washdown and corrosive environments. Equipped with a SUS304 stainless steel rod, it delivers a robust 982 N push force at 0.5 MPa alongside an 825 N pull force, utilizing a PT1/4 port and M16x1.5 rod-end thread.
Its extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting contamination. The integrated -S magnet enables precise position tracking with AirTAC CMSE reed or DMSE electronic sensors, and the field-adjustable air cushioning at both ends allows you to fine-tune end-of-stroke deceleration to protect payloads.

Where the Airtac SE50 Standard Cylinder SE50BX290SFTC Is Used
Flow Wrapper End-Seal Head
Drives the 290 mm stroke on a flow wrapper end-seal head, using the 982 N push force to cleanly crimp packaging film over varying product heights in washdown zones.
Stainless Steel Divert Gate
Actuates a divert gate on a stainless steel conveyor line, where the SUS304 rod resists moisture and the FTC mount handles the pivot load across the 290 mm travel.
Lab Sample Indexing Arm
Moves a lab sample indexing arm through 290 mm of travel, relying on the -S magnet and DMSE sensors to confirm position for automated fluid dispensing.
Is the Airtac SE50 Standard Cylinder SE50BX290SFTC the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 982 N of push force; if your application requires less force, the 40 mm bore offers 628 N, while stepping up to the 63 mm bore yields 1559 N for heavier loads. With its 290 mm stroke, the M16x1.5 rod and internal bearing face bending stresses under side loads, so an external guide rail is strongly recommended to prevent premature seal wear. The FTC mounting accessory provides rigid center-trunnion support, and because it adheres to ISO 15552 dimensions, it serves as a direct replacement for other ISO 15552 cylinders without needing new mounting holes. Note that this cylinder relies on live air pressure to move and hold loads; it will drift if air is lost, so consider a BSE rod lock for fail-safe holding.
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 SE50BX290SFTC FAQ
This 50 mm bore cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. It features a PT1/4 port, a 20 mm SUS304 rod, and an M16x1.5 rod-end thread.
Yes, it is dimensionally interchangeable with any ISO 15552 profile cylinder, sharing standard mounting interfaces and FTC trunnion dimensions. However, it is a standard double-acting cylinder, so it cannot hold a load if air pressure is lost; it will drift, requiring a BSE rod lock for fail-safe holding.
