Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50S 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 100mm stroke with a 50mm fine-adjustable window — settable from 50 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50S
The AirTAC PBJ10X100-50S is a double-acting, single-rod pen-size mini cylinder with a 50mm adjustable window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 50-100mm. You set the exact return position on the machine without buying new hardware. The extend end remains fixed. Output force matches a standard PB bore 10, yielding 39.3N push and 33N pull at 0.5MPa. The built-in magnet works with reed or electronic switches.
The SUS304 stainless body and rod provide corrosion resistance for tight jigs. A fixed TPU bumper cushions each end. Because the rod is only Ø4mm, add an external guide over this 100mm stroke to prevent side-load deflection. For safe sizing, plan for about 24N of real work at 0.5MPa, accounting for seal friction. The slim body uses an M5x0.8 port.

|---|---|
| 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 PBJ10X100-50S Is Used
Changeover Fixtures
Rapidly dial in the retract distance from 50 to 100mm when switching product families on shared tooling plates.
Trial Stop Positioning
Fine-tune the return endpoint during R&D testing to find the exact insertion depth before locking the adjuster nut.
Variable-Depth Insertion
Set precise retract heights for pressing different electronic connectors without swapping out the whole cylinder body.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-50S the Right Cylinder?
For lighter or heavier tasks, the bore 12 version provides 56.5N push, while no smaller PBJ exists below 10mm. When tuning this model, remember only the retract position shifts; the extend stop is fixed. After setting your depth, re-tighten the lock nut so vibration does not drift the screw. Confirm your ordering essentials: 10mm bore, 100mm nominal stroke, 50mm window, S magnet, and any LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–100 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 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 PBJ10X100-50S FAQ
It delivers 39.3N push and 33N pull at 0.5MPa, or 55N push and 46.2N pull at the 0.7MPa maximum. The effective stroke range is 50-100mm. The air port is M5x0.8.
The rear M4x0.7 screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. The S suffix indicates a built-in piston magnet compatible with reed or electronic switches.
