About the Airtac SE32 Standard Cylinder SE32BX840S
The AirTAC SE32BX840S 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 push force of 402 N at 0.5 MPa. The square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal pneumatics.
This 32 mm bore unit includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycling without relying on fixed rubber bumpers.

Where the Airtac SE32 Standard Cylinder SE32BX840S Is Used
Medical Equipment Washdown
The SUS304 rod resists corrosion in pharmaceutical cleanrooms, using its 402 N push force to actuate sterilization doors over the 840 mm travel.
Seafood Processing Transfer
Stainless steel components survive high-pressure washdowns, while the magnetic piston triggers DMSE sensors to index conveyor belts reliably.
Film Wrapping Mechanism
The adjustable end cushions soften the 840 mm stroke transitions, preventing packaging film tears during high-speed 30-800 mm/s wrapping cycles.
Is the Airtac SE32 Standard Cylinder SE32BX840S the Right Cylinder?
When sizing this cylinder, consider stepping down to a 20 mm bore (if available in a similar series) for lighter duty, or up to a 40 mm bore which provides a higher 628 N push at 0.5 MPa for heavier loads. As an 840 mm stroke exceeds the 1000 mm maximum standard stroke for this bore, this is a non-standard, made-to-order configuration. Because 840 mm is well over 300 mm, the unsupported stroke creates significant rod-bearing bending moments; an external guide is strongly recommended to prevent premature seal wear and side-load damage.
For drop-in retrofits, this cylinder is dimensionally interchangeable per ISO 15552 standards. It uses a PT1/8 port, an M10x1.25 rod thread, and 27 mm cushion strokes. Note that a plain SE cylinder does not hold its position when air is lost or the valve is centered, as the piston will drift. If your application requires true load holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve.
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 SE32 Standard Cylinder SE32BX840S FAQ
This 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa, the push force is 563 N. The maximum push force is 82 kgf at 1.0 MPa operating pressure.
Yes, the SE32BX840S is dimensionally interchangeable per ISO 15552 standards, allowing it to drop into existing footprints and use shared mounting hardware. The -S magnet also works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
