Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50 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 100mm stroke with a 50mm fine-adjustable window — settable from 50 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50
The AirTAC PBJ10X100-50 is a double-acting, single-rod pen-size mini cylinder with a 50mm adjustable stroke window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 50 to 100mm. Output force matches a standard PB cylinder of the same bore, delivering 39.3N push and 33N pull at 0.5MPa. The extend end remains fixed.
The body features a SUS304 stainless steel rod and barrel, plus a fixed TPU bumper at each end. Air ports are M5x0.8. Because the rod is a slender Ø4mm, use an external guide or linear bearing for any off-axis loads over this long 100mm travel. The adjuster is free of any force penalty. Plan for a safe working load of about 24N (roughly 60% of the 0.5MPa push force) to account for seal friction and smooth travel.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 50 mm (50–100 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 PBJ10X100-50 Is Used
Changeover Fixtures
Dial in the exact retract position during product changeovers without swapping physical hardware.
Trial Insertion Stops
Fine-tune insertion depth on test jigs to find the optimal position before finalizing the setup.
Variable Depth Pressing
Adjust the rear travel limit on the fly for pressing parts of differing heights.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50 the Right Cylinder?
For sizing context, dropping to a bore 12 yields 56.5N push at 0.5MPa, while this bore 10 provides 39.3N. If you need less stroke, a fixed PB10 saves complexity. Remember that only the back position is tunable; the 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: 10mm bore, 100mm nominal stroke, 50mm window, no magnet, and your preferred mounting. This plain cylinder does not hold position on air loss, so fit an external stop if fail-safe load holding is required.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–100 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 PBJ10X100-50 FAQ
The effective stroke range is 50 to 100mm. At 0.5MPa it provides 39.3N push and 33N pull. At the maximum 0.7MPa operating pressure, it yields 55N push and 46.2N pull.
A rear M4x0.7 screw shortens the retract end by up to 50mm, while the extend end stays fixed. You must re-tighten the lock nut after setting to prevent vibration drift.
