Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X90-20S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X90-20S 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 90mm stroke with a 20mm fine-adjustable window — settable from 70 to 90mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X90-20S
The AirTAC PBJ10X90-20S is a double-acting, single-rod pen-size mini cylinder with a 20mm adjustable window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 70-90mm. The extend end remains fixed. Output force matches a standard PB of the same 10mm bore, delivering 39.3N push and 33N pull at 0.5MPa.
This model includes a built-in magnet for position sensing. The slim SUS304 stainless body saves space in tight jigs. It uses an M5x0.8 air port and a fixed TPU bumper at each end. For a safe working load, plan for about 24N of real work at 0.5MPa, accounting for seal friction.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 90 mm |
| Adjustable window | 20 mm (70–90 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 PBJ10X90-20S Is Used
Trial Stop Positioning
Dial in the exact retract distance during prototype runs. Set the 70-90mm window on the machine without ordering new hardware for each test length.
Changeover Fixtures
Switch product variants quickly. The rear adjuster brings the tooling back to a new home position, while the fixed TPU bumper ensures consistent end-of-stroke deceleration.
Variable Depth Insertion
Press small components to varying depths. The 10mm bore provides repeatable force, and the built-in magnet confirms the extend position via electronic or reed switches.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X90-20S the Right Cylinder?
This 10mm bore provides 39.3N push at 0.5MPa. Stepping up to the 12mm bore yields 56.5N push, while dropping below 10mm is not standard for this series. Remember the rear screw only tunes the retract end; the extend position is fixed. Always re-tighten the lock nut after setting to prevent vibration drift.
Confirm your ordering essentials: 10mm bore, 90mm nominal stroke, 20mm window, S magnet, and any LB or FA mount. The Ø4mm rod is built for coaxial thrust, so add an external guide for off-axis loads over this 90mm stroke.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 70–90 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 PBJ10X90-20S FAQ
The effective stroke range is 70-90mm. Force is unchanged from a standard PB cylinder. At 0.5MPa it provides 39.3N push and 33N pull. At the maximum 0.7MPa operating pressure, it provides 55N push and 46.2N pull.
A rear M4x0.7 screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent drift. The S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches.
