The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S 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 65mm stroke with a 30mm fine-adjustable window — settable from 35 to 65mm, so you set the end position without changing hardware.
The AirTAC PBJ16X65-30S is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 35-65mm. 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 0.5 MPa. The built-in magnet works with reed or electronic switches.
The slim body uses a SUS304 stainless rod and barrel, plus a fixed TPU bumper at each end. The M5x0.8 port and Ø5mm rod handle coaxial thrust well. For real-world sizing, plan for a safe working load of about 60N (roughly 60% of the 0.5 MPa push figure). This equates to lifting about 5.1kg vertically with a 2:1 safety margin.

| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 65 mm |
| Adjustable window | 30 mm (35–65 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) |

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.
| 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.

Fixed body — no separate back-cover code. Mounting accessories: LB, FA. Related PB-family variants: PB (fixed stroke), PBD (double rod), PBR (front-mount).
Dial in the exact retract position when swapping product families on a shared jig, using the 35-65mm window to set new stops without machining new pins.
Gradually test insertion depths on delicate electronics, backing off the rear screw to prevent overtravel and crushing before finalizing the cycle.
Adjust the retract height of lightweight vertical lifts, matching different part thicknesses directly on the machine floor without replacing the actuator.
This 16mm bore provides 100.5N push at 0.5 MPa. Stepping down to a 12mm bore drops the push to 56.5N, while moving up is not applicable for this pen-size series at this stroke. Because the rear screw only alters the back position, ensure your layout accommodates the fixed extend end. Always re-tighten the lock nut after setting the 35-65mm range to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 65mm nominal stroke, 30mm window, S magnet, and any LB or FA mounts.
Quick checklist
The effective stroke range is 35-65mm. Force is identical to a standard PB 16mm bore cylinder: push is 100.5N and pull is 90.7N at 0.5 MPa. At the maximum 0.7 MPa operating pressure, push is 140.7N and pull is 126.9N.
The rear screw shortens the retract end only; the extend end is fixed. You set the desired length within the 30mm window, then re-tighten the lock nut to prevent vibration drift. The built-in S magnet is compatible with reed or electronic switches.
