Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø16mm bore it gives a nominal 65mm stroke with a 30mm fine-adjustable window — settable from 35 to 65mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30
The AirTAC PBJ16X65-30 is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable window. A rear M5x0.8 adjuster screw shortens the retract end, yielding an effective stroke range of 35-65mm. The extend end remains fixed. Output matches a standard PB body, delivering 100.5N push and 90.7N pull at 0.5MPa.
The SUS304 stainless build and slim 16mm body fit tight jigs. It uses an M5x0.8 port and a fixed TPU bumper. For real work at 0.5MPa, plan for a safe working load of about 60N. The Ø5mm rod handles coaxial thrust; add an external guide for off-axis loads.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 65 mm |
| Adjustable window | 30 mm (35–65 mm) |
| Adjuster thread | M5×0.8 |
| 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 200 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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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 PBJ16X65-30 Is Used
Variable-Depth Insertion
Dial in exact press depth on the machine using the rear screw. The 35-65mm range allows quick changeover for different insert heights without swapping cylinders.
Changeover Fixtures
Adapt retraction points quickly between product variants. The lock nut secures the adjusted position, maintaining repeatability across batch runs.
Trial Stop Positioning
Set temporary retract limits during prototype tooling. The fixed TPU bumper absorbs end-of-stroke impact while you tune the 35-65mm effective length.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30 the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If sizing neighbors, dropping to a 12mm bore drops push to 56.5N, while moving up is outside this pen-size family. The rear screw alters the back position only; the extend end is fixed. Always re-tighten the lock nut after setting to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 65mm nominal stroke, -30mm window, no magnet, and required mount. Note the thin Ø5mm rod is for axial thrust, not side load. A plain PBJ does not hold position on air loss; use an external stop for fail-safe holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 35–65 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 PBJ16X65-30 FAQ
The effective stroke range is 35-65mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the 0.7MPa maximum, it provides 140.7N push and 126.9N pull.
A rear M5x0.8 screw shortens the retract end only; the extend end is fixed. You set the length on the machine and re-tighten the lock nut to prevent vibration drift. Force remains unchanged.
