Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-75
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-75 is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø12mm bore it gives a nominal 100mm stroke with a 75mm fine-adjustable window — settable from 25 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-75
The AirTAC PBJ12X100-75 is a double-acting, double-rod pen-size mini cylinder with a 75mm adjustment window. A rear screw and lock nut shorten the retract end, yielding an effective stroke range of 25-100mm. You tune the exact length on the machine without ordering new hardware. The extend end remains fixed.
The slim SUS304 stainless body saves space in tight jigs. It uses an M5x0.8 port and a fixed TPU bumper at each end.

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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 46.7 N | 46.7 N |
| 0.7 MPa (max) | 65.4 N | 65.4 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 PBJ12X100-75 Is Used
Changeover Fixtures
Rapidly reconfigure product families by dialing the retract stop from 25mm up to 100mm, eliminating the need to swap physical cylinder hardware during format changes.
Trial Insertion Stops
Set precise insertion depths on the fly during prototype runs. The rear screw lets you micro-adjust the back position without risking over-travel on delicate components.
Variable Depth Pressing
Press sub-assemblies to exact varying depths using one cylinder. The fixed TPU bumper ensures consistent end-of-stroke deceleration across the adjusted range.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-75 the Right Cylinder?
Remember that the rear adjuster only alters the back position—the extend end is fixed. Always re-tighten the lock nut after setting your 25-100mm range to prevent vibration drift.
Confirm your ordering essentials: 12mm bore, 100mm nominal stroke, 75mm window, and your mounting option. The piston rod is a slender Ø5mm designed for coaxial thrust, so add an external guide or linear bearing for off-axis loads over this long stroke.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 25–100 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 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 PBJ12X100-75 FAQ
The effective stroke range is 25-100mm. Adjusting the stroke does not alter these force figures.
The rear M5x0.8 adjuster screw shortens only the retract end of the stroke, while the extend end remains fixed. After setting your desired length, you must re-tighten the lock nut to prevent vibration drift. This cylinder does not have a sensor magnet.
