Airtac SEJ Adjustable Cylinder SEJ100BX150-10S
The AirTAC SEJ Adjustable Cylinder SEJ100BX150-10S is a genuine double-acting ISO 15552 double-rod cylinder with a mechanically ADJUSTABLE stroke: a back-rod stop screw lets you fine-tune the retract end over a 10mm window, so this Ø100mm unit covers an effective stroke of 140–150mm without changing cylinders. Force is equal in both directions.

About the Airtac SEJ Adjustable Cylinder SEJ100BX150-10S
The AirTAC SEJ100BX150-10S is a double-acting, double-rod ISO 15552 profile cylinder engineered for exact positioning tasks. A stainless steel (SUS304) rod exits both ends, yielding identical extend and retract forces of 3681 N at 0.5 MPa and 5153 N at 0.7 MPa. The retract stroke is mechanically adjustable via a back-rod stop screw over a 10 mm window, providing an effective stroke range of 140 to 150 mm for dialing in a precise end position.
This bore 100 mm cylinder features a PT1/2 port, a Ø25 mm rod with an M20x1.5 thread, and field-adjustable air cushions at both ends to manage deceleration. The integrated -S magnet supports CMSE reed and DMSE electronic sensors for end-of-trroke confirmation. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR variants.
Airtac SEJ Adjustable Cylinder SEJ100BX150-10S Technical Specifications
| Model | Airtac SEJ Adjustable Cylinder SEJ100BX150-10S |
|---|---|
| Series | SEJ ISO 15552 adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 150 mm |
| Adjustment window | 10 mm (140–150 mm) |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |
Specifications follow the official AirTAC SEJ datasheet and ISO 15552 / VDMA 24562 dimensions. The adjustment screw shortens the retract end only; do not exceed the 10mm window. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 kgf |
A rod exits both ends, so extend and retract force are identical. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SEJ Adjustable Cylinder SEJ100BX150-10S Is Used
Packaging Press Changeover
Dial in the 140-150 mm effective stroke to match different carton fold depths, using the 5153 N both-way force to cleanly crease and seal varied packaging formats on the fly.
Washdown Sorting Gate
Leverage the SUS304 rod for corrosion resistance in food processing lines, adjusting the 10 mm retract window to precisely position diverter gates without re-mounting hardware.
Assembly Press Tuning
Fine-tune the pressing end-point during commissioning of dual-action assembly jigs, relying on the equal 3681 N extend and retract forces to maintain balanced clamping pressure.
Is the Airtac SEJ Adjustable Cylinder SEJ100BX150-10S the Right Cylinder?
Confirm the 10 mm adjustment window covers your positioning tolerance, letting you fine-tune the retract stop from 140 to 150 mm without swapping hardware. If you need less force, the 80 mm bore delivers 2268 N at 0.5 MPa both ways; if you need more, the 125 mm bore provides 5734 N at 0.5 MPa. A fixed-stroke SED cylinder is sufficient if your end position never varies. For machine changeovers, the SUS304 rod adds corrosion resistance for washdown environments. Note that the air cushion and stop screw only set the mechanical end and decelerate the load; they do not hold position on air loss. For fail-safe holding, use an external rod lock or a BSED variant. This unit is dimensionally interchangeable per ISO 15552—match the 100 mm bore, 150 mm stroke, PT1/2 port, and desired mounting bracket for direct replacement.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Adjustment window (10mm) covers your range
- ✓ Equal force both directions OK
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the stop screw within the 10mm window; lock it after adjusting.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SEJ Adjustable Cylinder SEJ100BX150-10S FAQ
The retract stroke is adjustable over a 10 mm window via a mechanical stop screw on the back rod, giving an effective stroke range of 140 to 150 mm. You lock the screw in place after setting the exact end position.
Because it is a double-rod cylinder, the force is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa. It is dimensionally interchangeable per ISO 15552, provided you match the 100 mm bore, 150 mm stroke, and PT1/2 port.
