Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X70-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X70-10S 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 70mm stroke with a 10mm fine-adjustable window — settable from 60 to 70mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X70-10S
The AirTAC PBJ16X70-10S is a double-acting, single-rod pen-size mini cylinder with a 10 mm adjustable window. A rear adjuster screw (M5x0.8 thread) shortens the retract end, giving an effective stroke range of 60-70 mm without changing hardware. The extend end remains fixed. Force is identical to a standard PB body, delivering 100.5 N push and 90.7 N pull at 0.5 MPa. The bore is 16 mm, the piston rod is Ø5 mm, and the air port is M5x0.8.
Built with a SUS304 stainless barrel and rod, this slim cylinder includes a built-in piston magnet for reed or electronic switches. A fixed TPU bumper cushions each end. For real-world sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa push figure) or a vertical lift of about 5.1 kg with a 2:1 margin. The Ø5 mm rod handles coaxial thrust; use an external guide for off-axis loads.

| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 70 mm |
| Adjustable window | 10 mm (60–70 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) |
| Max standard stroke | Up to 200 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 (Ø16mm)
| 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.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X70-10S Is Used
Variable-Depth Insertion
Dial in precise pressing depths during trial runs. The rear screw tunes the retract end from 60 to 70 mm so you can perfect insertion without swapping cylinders.
Quick Changeover Fixtures
Adapt pick-and-place jigs to new part heights instantly. The on-machine adjuster saves re-ordering hardware for a slightly shorter retract stroke.
Trial Stop Positioning
Set exact end-of-stroke stops for testing. The built-in magnet works with electronic switches to confirm position while you trim the 10 mm window.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X70-10S the Right Cylinder?
When sizing this 16 mm bore, note the neighbouring capacities: a 12 mm bore provides 56.5 N push, while this 16 mm offers 100.5 N at 0.5 MPa. If you need fixed lengths, choose the PB series; for equal push and pull force, select the PBD double-rod version. Remember that only the retract position is field-settable. Always re-tighten the lock nut after setting the 60-70 mm range to prevent vibration drift. Confirm your ordering essentials: 16 mm bore, 70 mm nominal stroke, 10 mm window, S magnet, and mounting option.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 60–70 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 PBJ16X70-10S FAQ
The effective stroke range is 60-70 mm. At 0.5 MPa it provides 100.5 N push and 90.7 N pull. At the maximum 0.7 MPa operating pressure, it yields 140.7 N push and 126.9 N pull. These forces match a standard PB cylinder of the same bore.
The rear M5x0.8 screw shortens only the retract end; the extend end is fixed. Set your length, then tighten the lock nut to prevent vibration drift. The S suffix means a built-in magnet for position sensing, compatible with AirTAC reed or electronic switches.
