Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X75-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X75-50 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 75mm stroke with a 50mm fine-adjustable window — settable from 25 to 75mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X75-50
The AirTAC PBJ10X75-50 is a double-acting, single-rod pen-size mini cylinder with a 50mm adjustment window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 25-75mm. You set the exact length on the machine without changing hardware. The extend end remains fixed.
Output force matches a standard PB cylinder of the same bore, giving 39.3N push at 0.5MPa with no penalty for the adjustment. The slim SUS304 stainless body saves space in tight jigs. The M5x0.8 port and fixed TPU bumper keep the build compact. Plan for a safe working load of about 24N (roughly 60% of the 0.5MPa figure) 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 | 75 mm |
| Adjustable window | 50 mm (25–75 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) |

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 PBJ10X75-50 Is Used
Changeover Fixtures
Quickly dial in the 25-75mm retract length when switching between product sizes on a shared fixture, eliminating the need to swap cylinders.
Trial Stops
Set precise back positions for prototype testing and sensing probes, locking the nut once the optimal travel distance is found.
Variable-Depth Insertion
Adjust the retract depth for pressing pins or plugs of varying heights without reordering hardware for each new part.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X75-50 the Right Cylinder?
This 10mm bore provides 39.3N push at 0.5MPa. If you need less force, a smaller option lacks the power for moderate clamping, while a 12mm bore gives 56.5N push for heavier loads. Remember that only the retract position is adjustable; the extend end is fixed. Always re-tighten the lock nut after setting your 25-75mm range to prevent vibration drift. Confirm your ordering essentials: 10mm bore, 75mm nominal stroke, 50mm window, and any mounting options like LB or FA.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 25–75 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 PBJ10X75-50 FAQ
The effective stroke range is 25-75mm. At 0.5MPa it provides 39.3N push and 33N pull. At the maximum 0.7MPa pressure, it provides 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. The piston rod is only 4mm, so use an external guide for off-axis loads.
