Airtac SEJ Adjustable Cylinder SEJ63BX150-10S
The AirTAC SEJ Adjustable Cylinder SEJ63BX150-10S 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 Ø63mm unit covers an effective stroke of 140–150mm without changing cylinders. Force is equal in both directions.

About the Airtac SEJ Adjustable Cylinder SEJ63BX150-10S
The AirTAC SEJ63BX150-10S is a double-acting, double-rod ISO 15552 profile cylinder featuring a SUS304 stainless steel rod for corrosion resistance. A rod exits both ends, ensuring the annulus area remains identical in both directions. This delivers an equal output force of 1402 N each way at 0.5 MPa.
The retract end is mechanically adjustable via a back-rod stop screw, providing a 10 mm dial-in window that sets the effective stroke range from 140 to 150 mm. You can fine-tune the exact end position on the machine during commissioning and lock it down. The built-in -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.
Airtac SEJ Adjustable Cylinder SEJ63BX150-10S Technical Specifications
| Model | Airtac SEJ Adjustable Cylinder SEJ63BX150-10S |
|---|---|
| Series | SEJ ISO 15552 adjustable-stroke cylinder |
| Bore size | Ø63 mm |
| Nominal stroke | 150 mm |
| Adjustment window | 10 mm (140–150 mm) |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M16×1.5 |
|---|---|
| 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SEJ63BX150-10S Is Used
Washdown Stop Tuning
Dial in the 140-150 mm retract stop on a SUS304-equipped food packaging press to precisely match varying product thicknesses without changing hardware.
Changeover Positioning
Leverage the 1402 N both-way force and 10 mm adjustment window to rapidly set new mechanical end stops on a bottling line during format changeovers.
Trial Actuation Setup
Fine-tune the exact clamping position on a testing fixture during R&D commissioning, locking the back-rod stop screw once the optimal stroke is found.
Is the Airtac SEJ Adjustable Cylinder SEJ63BX150-10S the Right Cylinder?
Verify the 10 mm adjustment window covers your required end-position variance. If you need less force, the 50 mm bore offers 825 N at 0.5 MPa; if you need more, stepping up to the 80 mm bore yields 2268 N at 0.5 MPa. If the stroke never varies, a fixed-stroke SED avoids the extra length. For direct ISO 15552 replacement, match the 150 mm stroke, PT3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the air cushion decelerates the load near stroke end but does not hold position on air loss; for fail-safe holding, specify a BSED or an external rod lock.
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 SEJ63BX150-10S FAQ
The retract end features a 10 mm adjustment window via a back-rod stop screw, allowing the effective stroke to be dialed in anywhere from 140 to 150 mm. You set the exact end position on the machine and lock it down.
Because it is a double-rod cylinder, the force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
