Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-75S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-75S 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 75mm fine-adjustable window — settable from 100 to 175mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-75S
The AirTAC PBJ10X175-75S is a double-acting, single-rod pen-size mini cylinder with a 75mm adjustable-stroke window. A rear adjuster screw (M4x0.7) and lock nut shorten the retract end, giving an effective stroke range of 100-175mm. The extend end remains fixed. Output force is identical to a standard PB cylinder of the same bore, delivering 39.3N push and 33N pull at 0.5MPa. This 175mm stroke exceeds the 100mm standard maximum for a 10mm bore, making it a non-standard, made-to-order part.
Built with a SUS304 stainless barrel and a slim 10mm body, it saves space in tight jigs and light end-of-arm tooling. It features a fixed TPU bumper at each end for end-of-stroke deceleration. The -S suffix indicates a built-in piston magnet for position sensing with reed or electronic switches. The air port is M5x0.8, and the rod-end thread is M8x1.0. For practical sizing, plan for a safe working load of about 24N (roughly 60% of the 0.5MPa push force) or a vertical lift of about 2kg with a 2:1 margin.

| Nominal stroke | 175 mm |
| Adjustable window | 75 mm (100–175 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 PBJ10X175-75S Is Used
Variable-Depth Insertion
Dial in exact press depths for different part heights on a single fixture by adjusting the retract end from 100 to 175mm without swapping hardware.
Changeover Fixtures
Speed up machine changeovers by turning the rear M4x0.7 adjuster screw to set new positions for multiple product variants on the same line.
Light Vertical Lifts
Move lightweight components vertically; the 10mm bore safely handles about 2kg with a 2:1 margin, while the magnet confirms retraction.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-75S the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: a 12mm bore provides 56.5N push, while smaller options offer less thrust. The 10mm bore provides 39.3N push at 0.5MPa, which is sufficient for light pick-and-place tasks. Remember that only the retract position is field-settable; the extend end is fixed. After setting your exact length, re-tighten the lock nut to prevent vibration drift. Because the stroke is 175mm on a thin Ø4mm rod, add an external guide or linear bearing to prevent side-load damage over this long distance. Confirm your ordering essentials: 10mm bore, 175mm nominal stroke, 75mm window, S magnet, and mounting option.
For load holding, note that a plain double-acting cylinder drifts on air loss. The fixed TPU bumper only decelerates the last few millimetres of travel; it cannot hold a load without live pressure. If your application requires a fail-safe hold, specify an external stop or a separate rod lock. At higher cycling speeds with real tooling mass, meter-out the exhaust or add an external shock absorber to prevent the bumper from bottoming out.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 100–175 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 PBJ10X175-75S FAQ
The effective stroke range is 100-175mm (175mm nominal minus a 75mm window). Force is identical to a standard PB 10mm bore: 39.3N push and 33N pull at 0.5MPa, or 55N push and 46.2N pull at the 0.7MPa maximum. The air port is M5x0.8.
The rear adjuster screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The -S suffix means a built-in piston magnet is fitted, allowing you to use reed or electronic switches for position sensing.
