About the Airtac SE40 Standard Cylinder SE40BX900
The AirTAC SE40BX900 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 40mm bore and a 900mm stroke. Because this stroke exceeds the standard 800mm maximum for this bore, it is supplied as a made-to-order unit. It delivers a 628 N push force at 0.5 MPa and features a PT1/4 port. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight spaces.
This specific configuration utilizes a SUS304 stainless steel rod (material code B) for superior resistance to moisture and corrosive environments. The cylinder incorporates field-adjustable air cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw. Note that this SKU is built without a position-sensing magnet, so it is not wired for CMSE or DMSE electronic switches out of the box.

Where the Airtac SE40 Standard Cylinder SE40BX900 Is Used
Bottling Line Divert Gate
Actuates a 900mm routing gate on a beverage bottling line, where the SUS304 rod withstands washdowns and the 628N force easily shifts full cartons.
Textile Fabric Stretching
Extends across a wide loom to tension and clamp synthetic fabric webs, utilizing the full 900mm stroke and the corrosion-resistant stainless steel rod.
Lab Coating Dispenser
Drives a 900mm traverse carriage for a chemical dispensing head, relying on the smooth double-acting action and field-adjustable end cushions to prevent splashing.
Is the Airtac SE40 Standard Cylinder SE40BX900 the Right Cylinder?
Selecting the SE40BX900 is appropriate when your mechanism requires a 628 N push at 0.5 MPa across a 900mm span. If your application demands less force, stepping down to the 32mm bore yields a 402 N push, while moving up to the 50mm bore provides a 982 N push for heavier payloads. Because this is a 900mm stroke, the 16mm rod and piston bearing face significant bending moments under side loads; an external guide rail is strongly recommended to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders, sharing standardized mounting interfaces like FA or LB. Remember that a standard SE cylinder does not hold its load when air pressure is lost—the adjustable cushion only decelerates the piston near stroke end, so pair it with a BSE rod lock if static holding is required.
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 SE40BX900 FAQ
The SE40BX900 delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 879 N, with a maximum push of 128 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s within a 0.15-1.0 MPa pressure range.
No, a standard SE cylinder will drift if air is lost or the valve is centered. The adjustable air cushion at both ends only decelerates the piston near the stroke limits; it does not act as a brake. For position holding, consider an AirTAC BSE series rod lock.
