Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20S 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 20mm fine-adjustable window — settable from 80 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20S
The AirTAC PBJ10X100-20S is a double-acting, single-rod pen-size mini cylinder with a 10 mm bore and a 100 mm nominal stroke. A rear adjuster screw (M4x0.7 thread) shortens the retract end, giving an effective stroke range of 80-100 mm. You set the exact back position on the machine without buying new hardware. The extend end remains fixed. Output force matches a standard PB cylinder of the same bore, delivering 39.3 N push at 0.5 MPa.
Built with a SUS304 stainless steel rod and barrel, this slim cylinder saves space in tight jigs and light end-of-arm tooling. It features a fixed TPU bumper at each end and a built-in piston magnet (-S) for position sensing. The M5x0.8 port matches the 10 mm bore size. For smooth operation, plan for a safe working load of about 24 N, which is roughly 60% of the 0.5 MPa push rating, accounting for seal friction.

| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 20 mm (80–100 mm) |
| Adjuster thread | M4×0.7 |
| 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 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 PBJ10X100-20S Is Used
Changeover Fixtures
Dial in the 80-100 mm retract position during product changeovers. The rear screw lets operators set new stops rapidly without machining replacement spacers.
Trial Stops
Set precise end-of-stroke limits for prototype tooling. You can tune the retract distance in 1 mm increments and lock the nut once the optimal position is found.
Variable Insertion
Control insertion depth on light assembly lines. The 39.3 N push force at 0.5 MPa handles delicate tasks while the adjuster allows quick depth changes.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20S the Right Cylinder?
This 10 mm bore provides 39.3 N push at 0.5 MPa. If you need less force, the smaller bore options offer lower thrust; if your fixture requires more power, stepping up to a 12 mm bore yields 56.5 N push. Remember that adjusting the stroke only affects the retract end—the extend position is fixed. After dialing in your 80-100 mm range, re-tighten the lock nut so vibration does not drift the M4x0.7 screw.
Confirm your ordering essentials: 10 mm bore, 100 mm nominal stroke, 20 mm adjuster window, S magnet, and any LB or FA mounting hardware. The Ø4 mm piston rod is built for coaxial thrust; over this 100 mm stroke or with off-axis loads, add an external guide or linear bearing to prevent side-load damage.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 80–100 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 PBJ10X100-20S FAQ
The effective stroke range is 80-100 mm (nominal 100 mm minus the 20 mm adjuster window). Force is identical to a standard PB 10 mm cylinder: 39.3 N push and 33 N pull at 0.5 MPa; 55 N push and 46.2 N pull at the 0.7 MPa maximum.
The rear M4x0.7 screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The built-in magnet (-S) works with AirTAC reed or electronic switches for position sensing.
