Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø10mm bore it gives a nominal 175mm stroke with a 40mm fine-adjustable window — settable from 135 to 175mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S
The AirTAC PBJ10X175-40S is a double-acting, single-rod pen-size mini cylinder with a 40mm adjustable stroke window. A rear adjuster screw and lock nut shortens the retract end, giving an effective stroke range of 135-175mm. The extend end remains fixed. Output force equals a standard PB body of the same bore, yielding 39.3N push and 33N pull at 0.5MPa. This 175mm unit is a made-to-order part because it exceeds the 100mm max standard stroke for a 10mm bore.
Built with a SUS304 stainless barrel and a slim 4mm rod, it fits tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions each end. The -S denotes a built-in piston magnet for reed or electronic switches. The M5x0.8 port and M8x1.0 rod-end thread match the 10mm bore standard. Because the 4mm rod is slender over 175mm, use an external guide to prevent side-load deflection. Plan for a safe working load of about 24N (60% of the 0.5MPa push) or a vertical lift of roughly 2kg with a 2:1 margin.

| Rod diameter | Ø4 mm |
| Nominal stroke | 175 mm |
| Adjustable window | 40 mm (135–175 mm) |
| Adjuster thread | M4×0.7 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 100 mm |
The adjuster shortens only the retract end; the extend end is fixed. Force is unchanged from the standard PB double-acting cylinder. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 N |
Adjusting the stroke does not change output force — these are the same values as the standard PB double-acting cylinder of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S Is Used
Changeover Fixtures
Dial in the retract stop from 135 to 175mm during product changeovers without swapping hardware.
Trial Stops
Set a precise retract position for test-fitting parts, then lock the M4x0.7 adjuster nut once verified.
Variable Depth Insert
Tune the back position for different insertion depths on a slim 10mm bore tooling head.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S the Right Cylinder?
For sizing context, dropping to a 12mm bore raises push to 56.5N at 0.5MPa, while staying at 10mm gives exactly 39.3N. When ordering, confirm your nominal 175mm stroke, the 40mm adjuster window, the S magnet option, and any LB or FA mount. Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after tuning to prevent vibration drift.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 135–175 mm
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Access to the rear adjuster screw
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Set the adjuster, then re-lock the check nut.
- check The adjuster shortens the retract end only.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40S FAQ
The effective stroke range is 135-175mm. At 0.5MPa the force is 39.3N push and 33N pull. At the 0.7MPa maximum, force is 55N push and 46.2N pull.
The rear screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to stop drift. The cylinder does not hold load on air loss, so fit an external stop for fail-safe holding.
