Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-40S 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 80mm stroke with a 40mm fine-adjustable window — settable from 40 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-40S
The AirTAC PBJ10X80-40S is a JIS pen-size double-acting mini cylinder with a 40mm rear adjuster window. You set the effective stroke from 40mm up to the 80mm nominal length right on the machine, avoiding hardware reorders for changeovers. The extend end remains fixed; only the retract position moves. Force matches the standard PB series of the same bore, delivering 39.3N push and 33N pull at 0.5MPa. The M5x0.8 port and Ø4mm stainless rod keep the body slim.
A fixed TPU bumper decelerates the last few millimeters at each end. The built-in magnet works with reed or electronic switches. Because the thin 4mm rod is built for coaxial thrust, add an external guide if you have off-axis loads over this 80mm travel. The rear adjuster uses an M4x0.7 thread; re-tighten the lock nut after setting to prevent vibration drift.

| Rod diameter | Ø4 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 40 mm (40–80 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 PBJ10X80-40S Is Used
Changeover Fixtures
Dial in the retract from 40 to 80mm on the spot to switch product families without machining new stops.
Trial Stops
Fine-tune the back position during prototype runs to find the exact insertion depth before locking the nut.
Variable Lift Jigs
Lift roughly 2kg of tooling vertically through a set range, using the 2:1 force margin for smooth travel.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-40S the Right Cylinder?
For lighter tasks, the smaller bore yields 39.3N push at 0.5MPa, while stepping up to the 12mm bore gives 56.5N if you need more force. This 10mm bore model provides a safe working load of about 24N, which is roughly 60% of its theoretical 0.5MPa force. It can vertically lift about 2kg with a 2:1 margin. Confirm your ordering essentials: 10mm bore, 80mm nominal stroke, 40mm adjust window, S magnet, and any LB or FA mount.
Remember that the rear screw only alters the retract end. Plan your layout so the extended position stays fixed. Also, a plain pneumatic body does not hold position on air loss; the piston drifts, so use an external stop for fail-safe holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 40–80 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 PBJ10X80-40S FAQ
The effective stroke range is 40-80mm. At 0.5MPa it provides 39.3N push and 33N pull. At the 0.7MPa maximum, it provides 55N push and 46.2N pull. Force stays identical to a standard PB cylinder of the same bore.
The rear M4x0.7 screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The S suffix means a built-in magnet for reed or electronic switches.
