About the Airtac SE50 Standard Cylinder SE50BX400
The AirTAC SE50BX400 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 400 mm stroke. It features a robust square extruded aluminum barrel that entirely eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. Equipped with a SUS304 stainless steel piston rod (material code B), this unit is purpose-built for corrosive environments and washdown duty.
Delivering 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, it integrates field-adjustable pneumatic cushioning at both ends. This allows technicians to fine-tune the end-of-stroke deceleration via a set screw, effectively softening hard mechanical impacts during high-speed 30-800 mm/s operations. Note that this specific SKU lacks a built-in magnet, meaning it is not ready out-of-the-box for CMSE or DMSE position sensing.

Where the Airtac SE50 Standard Cylinder SE50BX400 Is Used
Flow Wrapper Infeed
Drives the product pusher infeed on a stainless food packaging line, utilizing the 982 N thrust and SUS304 rod to withstand daily high-pressure washdowns.
Bottling Line Diverter
Actuates the lane diverter gate over a 400 mm travel distance, using adjustable cushioning to softly stop the high-speed diverting arm without jarring the conveyor frame.
Lab Sample Dispenser
Moves delicate fluid dispensing heads across testing stations, where the corrosion-resistant SUS304 rod prevents contamination from chemical reagents.
Is the Airtac SE50 Standard Cylinder SE50BX400 the Right Cylinder?
When sizing this actuator, consider stepping down to the 40 mm bore if your load requires only 628 N of push at 0.5 MPa, or moving up to the 63 mm bore if you need a substantially higher 1559 N thrust. Because this is a 400 mm stroke, the unsupported rod length increases the risk of side-load bending at the rod bearing; integrating an external guide rail is highly recommended to prevent premature seal wear. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 profile cylinders, utilizing the standard PT1/4 port and standard mounting hardware. Remember that the adjustable air cushion only decelerates the piston near stroke end and will not hold a load if air pressure is lost.
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 SE50BX400 FAQ
The SE50BX400 generates 982 N of push force and 825 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It uses a PT1/4 port and a 20 mm rod with an M16x1.5 thread.
Yes, the SE50BX400 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a retrofit for other ISO 15552 profile cylinders using the same mounting accessories and footprint, without needing to drill new holes.
