About the Airtac SE40 Standard Cylinder SE40BX900SN
The AirTAC SE40BX900SN is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 900 mm stroke. It features a robust 40 mm bore that generates 628 N of push force at 0.5 MPa, making it well-suited for long-travel linear motion tasks. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush within tight machinery envelopes.
Equipped with a SUS304 stainless steel rod and an NBR seal, this variant is built specifically for corrosive or washdown environments. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors for precise end-position detection, while the field-adjustable air cushioning at both ends allows you to fine-tune deceleration and soften hard end stops during high-speed operations.

Where the Airtac SE40 Standard Cylinder SE40BX900SN Is Used
Flow Wrapper Infeed
Drives the long-travel pusher arm on a packaging line, utilizing the 628 N push force and SUS304 rod to withstand regular washdown cycles in food processing facilities.
Pallet Transfer Reject
Actuates a 900 mm reject gate on a conveyor system, where the extended stroke moves heavy product lanes and the NBR seal resists degraded ambient oils.
Lab Sample Shuttle
Moves sample racks between testing stations in a high-humidity laboratory, relying on the DMSE electronic sensors and stainless steel rod for precise, corrosion-free cycling.
Is the Airtac SE40 Standard Cylinder SE40BX900SN the Right Cylinder?
Stepping down to a 32 mm bore yields 402 N of push at 0.5 MPa, whereas moving up to a 50 mm bore provides 982 N, letting you scale thrust precisely for your payload. Because this 900 mm stroke exceeds the 40 mm bore's 1200 mm maximum standard length, it is manufactured as a non-standard, made-to-order unit. At extended lengths, the 16 mm rod is highly susceptible to side-load bending; always support the load with an external guide to prevent premature rod-bearing wear. Remember that the adjustable air cushion only decelerates the piston near the stroke end—it will not hold a load vertically if air pressure is lost, so a BSE rod lock is required for fail-safe positioning. As a true ISO 15552 profile cylinder, it serves as a direct dimensional replacement sharing standard mounting hardware.
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 SE40BX900SN FAQ
The SE40BX900SN delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. It uses a PT1/4 port and features a 16 mm rod with an M12x1.25 thread.
