Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S
The AirTAC PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. 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.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S
The AirTAC PBJ16X65-30S is a double-acting, double-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. 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.

PBJ is a double-rod cylinder: the rear rod carries the stroke adjuster, which sets the stroke end within the adjustable window. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 90.7 N | 90.7 N |
| 0.7 MPa (max) | 126.9 N | 126.9 N |
The rear rod passes through the rear cover, so both piston faces lose rod area: push is shown at the annular-area value (conservative), lower than a single-rod PB push of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S Is Used
Changeover Fixtures
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.
Trial Insertion Stops
Gradually test insertion depths on delicate electronics, backing off the rear screw to prevent overtravel and crushing before finalizing the cycle.
Variable Lift Jigs
Adjust the retract height of lightweight vertical lifts, matching different part thicknesses directly on the machine floor without replacing the actuator.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-30S the Right Cylinder?
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
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 35–65 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 Double rod: the rear rod carries the stroke adjuster.
- 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 PBJ16X65-30S FAQ
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.
