About the Airtac SE40 Standard Cylinder SE40BX320S
The AirTAC SE40BX320S is a double-acting, single-rod ISO 15552 profile cylinder engineered for rigorous pneumatic duty. It generates 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for mid-range actuation tasks.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance in washdown environments, alongside a built-in magnet (code S) for seamless integration with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel omits external tie rods for a clean, compact footprint, while field-adjustable air cushions at both ends allow you to precisely tune end-of-stroke deceleration.

Where the Airtac SE40 Standard Cylinder SE40BX320S Is Used
Flow Wrapper End-Seal Jaw
Drives the mechanical sealing jaw on continuous-motion flow wrappers, utilizing the 320 mm stroke to clear the film web fully during product changeovers.
Lab Bottle Rinse Station
Lowers rinse nozzles into glass containers, leveraging the SUS304 stainless rod to withstand deionized water spray and harsh chemical washdowns.
Pallet Divert Gate
Actuates a routing flap on a 24V DC conveyor, using the built-in magnet to trigger DMSE solid-state sensors for precise package handoff timing.
Is the Airtac SE40 Standard Cylinder SE40BX320S the Right Cylinder?
Generating 628 N of thrust at 0.5 MPa, this 40 mm bore sits neatly between the 32 mm option (402 N push) and the 50 mm option (982 N push), allowing you to scale up or down depending on your exact load requirements. For retrofits, it offers true ISO 15552 dimensional interchangeability, sharing standard mounting interfaces and PT1/4 ports with comparable profiles.
Because the 320 mm stroke creates a long unsupported rod span, side loads can induce bending moments at the rod bearing; an external guide is strongly recommended to prevent premature wear. Note that while the adjustable cushions soften impact, this cylinder will drift if air pressure is lost and cannot hold a load without live pressure or an external rod lock.
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 SE40 Standard Cylinder SE40BX320S FAQ
This cylinder delivers 628 N of push force and 528 N of pull force at 0.5 MPa, 879 N of push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. It features a PT1/4 port and a 16 mm rod with an M12x1.25 thread.
