Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10 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 55mm stroke with a 10mm fine-adjustable window — settable from 45 to 55mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10
The AirTAC PBJ16X55-10 is a double-acting, single-rod pen-size mini cylinder with a 10mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 45-55mm. You set the exact return length right on the machine during commissioning. The extend end remains fixed.
Output force matches a standard PB cylinder of the same bore, delivering 100.5N push and 90.7N pull at 0.5MPa with no penalty for the adjustment feature. The slim SUS304 stainless body saves space in tight jigs. It uses an M5x0.8 air port, a fixed TPU bumper at each end, and a Ø5mm rod. Plan for a safe working load of about 60N (roughly 60% of the 0.5MPa push figure) to account for seal friction and smooth travel.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 55 mm |
| Adjustable window | 10 mm (45–55 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 PBJ16X55-10 Is Used
Trial Insertion Stops
Dial in the exact 45-55mm return depth for a press-fit operation without swapping hardware during prototype runs.
Changeover Fixtures
Quickly reset the retract length on a multi-product line to accommodate different part heights and reduce tooling downtime.
Variable Depth Stops
Set precise back positions for light-end-of-arm tooling tasks where a fixed 55mm stroke would bottom out the tool.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10 the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, stepping down to a 12mm bore yields 56.5N push; stepping up is not available in this pen-size series. Remember that only the back position is adjustable—your extend end is fixed. Always re-tighten the lock nut after setting the rear screw, as vibration can drift an unlocked mechanism.
Confirm your ordering essentials: 16mm bore, 55mm nominal stroke, 10mm window, no magnet, and your preferred mounting. This cylinder does not hold position on air loss, so add an external stop if fail-safe holding is required.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 45–55 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 PBJ16X55-10 FAQ
The effective stroke range is 45-55mm. It delivers 100.5N push and 90.7N pull at 0.5MPa, and 140.7N push and 126.9N pull at the 0.7MPa maximum. These forces are identical to a standard PB cylinder of the same bore.
A rear M5x0.8 screw shortens the retract end by up to 10mm, while the extend end is fixed. After setting your desired length, re-tighten the lock nut to prevent vibration drift. The cylinder has no sensor magnet.
