Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40 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 PBJ10X175-40
The AirTAC PBJ10X175-40 is a double-acting, single-rod pen-size mini cylinder with a 175mm nominal stroke and a 40mm adjustable window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 135-175mm. You can tune the stroke on the machine without swapping hardware. The extend end remains fixed. This bore uses an M5x0.8 air port and a Ø4mm piston rod with an M8x1.0 rod-end thread. A fixed TPU bumper decelerates the last few millimeters of travel at each end. Force is identical to a standard PB body, delivering 39.3N push and 33N pull at 0.5MPa. Because the 175mm length exceeds the 100mm standard maximum for this bore, this unit is non-standard and made-to-order.
The slim SUS304 stainless body fits tight jigs and light end-of-arm tooling. Plan for a safe working load of about 24N, which is roughly 60% of the 0.5MPa theoretical push, to account for seal friction. For vertical lifts, expect to raise about 2kg safely using a 2:1 margin. The Ø4mm rod is built for coaxial thrust; over long strokes or with off-axis loads, add an external guide or linear bearing to prevent side-load damage. A plain cylinder does not hold position on air loss; the piston drifts and the bumper only decelerates near stroke end, so use an external rod lock for fail-safe holding.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| 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 PBJ10X175-40 Is Used
Changeover Fixtures
Dial in the exact retract length during product changeovers without machining new hard stops or reordering cylinders.
Trial Stops
Fine-tune the end position in R&D and lab test rigs to find the optimal travel before committing to a fixed stroke.
Variable-Depth Insert
Adjust the retract distance on the fly for light insertion tasks requiring varying depths without changing the tool setup.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-40 the Right Cylinder?
When sizing, note that a smaller bore is unavailable in this pen series, while the next size up (Ø12mm) yields 56.5N push at 0.5MPa. If your fixture only needs 39.3N push, this Ø10mm bore is correct. Remember that only the retract position is field-adjustable; the extend end is fixed. After setting your 135-175mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: bore, 175mm nominal stroke, 40mm window, and mount. This unit lacks a magnet; if you need position sensing, select a model with the S suffix for a reed or electronic switch.
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 PBJ10X175-40 FAQ
The effective stroke range is 135-175mm (nominal 175 minus a 40mm window). At 0.5MPa it provides 39.3N push and 33N pull. At the 0.7MPa maximum, it yields 55N push and 46.2N pull. The air port is M5x0.8.
A rear M4x0.7 adjuster screw shortens the retract end only; the extend end is fixed. You set the desired length and then re-tighten the lock nut to prevent vibration drift. No sensor magnet is installed on this base model.
