Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-50 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 60mm stroke with a 50mm fine-adjustable window — settable from 10 to 60mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-50
The AirTAC PBJ16X60-50 is a double-acting, single-rod pen-size mini cylinder featuring a 50mm adjustable window. A rear adjuster screw (M5x0.8 thread) shortens the retract end, giving an effective stroke range of 10-60mm. You set the exact length on the machine without ordering new hardware. The extend end remains fixed. The air port is M5x0.8 and the rod-end thread is M10x1.0.
Force output remains identical to a standard PB cylinder of this bore, delivering 100.5N push and 90.7N pull at 0.5MPa. The Ø5mm stainless rod and barrel provide a slim profile for tight jigs. A fixed TPU bumper decelerates the last few mm of travel. For a practical safety margin, plan for a working load of about 60N at 0.5MPa, accounting for seal friction and smooth travel.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 60 mm |
| Adjustable window | 50 mm (10–60 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 PBJ16X60-50 Is Used
Changeover Fixtures
Rapidly tune the 10-60mm retract length when swapping product families on a shared jig, skipping the need to physically swap cylinders for different part heights.
Trial Stops
Dial in the exact extend-and-retract distance during prototype testing, locking the M5x0.8 adjuster nut once the optimal contact position is found.
Variable-Depth Insert
Press pins or plugs to precise varying depths using the rear screw, achieving consistent insertion without machining custom spacers for each task.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-50 the Right Cylinder?
For sizing context: the smaller 12mm bore offers 56.5N push at 0.5MPa, while the 16mm bore here provides 100.5N. If you need higher force, note this 16mm bore reaches 140.7N push at the 0.7MPa maximum. Remember that only the retract position is field-adjustable; the extend end is fixed. Always re-tighten the lock nut after setting the rear screw to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 60mm nominal stroke, 50mm adjuster window, no magnet, and your preferred mounting. This plain PBJ cylinder does not hold position on air loss—the piston drifts without live pressure, so add an external stop for fail-safe load holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 10–60 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 PBJ16X60-50 FAQ
The effective stroke range is 10-60mm (nominal 60mm minus up to a 50mm window). Forces equal a standard 16mm PB cylinder: 100.5N push and 90.7N pull at 0.5MPa; 140.7N push and 126.9N pull at the 0.7MPa maximum.
A rear screw shortens the retract end only, while the extend end remains fixed. After setting your desired length, re-tighten the lock nut to prevent vibration drift. This model has no built-in magnet.
