Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75S 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 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 PBJ10X100-75S
The AirTAC PBJ10X100-75S 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) with a lock nut lets you shorten the retract end, giving an effective stroke range of 25-100 mm. It includes a built-in piston magnet for reed or electronic switches. The M5x0.8 port and Ø4 mm stainless rod keep the frame slim for tight spaces.
Force stays identical to a standard PB cylinder of this bore, meaning you get 39.3 N push and 33 N pull at 0.5 MPa with zero penalty for adding adjustability. The extend end remains fixed, so only the back position is tunable. A fixed TPU bumper cushions each end, and the stainless build resists wear in demanding environments.

| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 75 mm (25–100 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 PBJ10X100-75S Is Used
Changeover Fixtures
Dial in the retract stop from 25 to 100 mm during product changeovers without machining new hard stops or reordering cylinders.
Trial Insertion Stops
Safely test variable-depth insertion pins by tuning the rear screw, locking the nut, and verifying contact before full production.
Light EOAT Positioning
Mount on end-of-arm tooling where the slim 10 mm body saves weight and the stroke can be trimmed to match varied gripper travel.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75S the Right Cylinder?
When sizing, compare neighbours: a smaller bore lacks the frame, while a 12 mm bore yields 56.5 N push at 0.5 MPa if you need more force. For this 10 mm bore, plan for a safe working load of about 24 N (roughly 60% of the 39.3 N theoretical push) to account for seal friction. The thin Ø4 mm rod is built for coaxial thrust, so over this 100 mm stroke you should add an external guide or linear bearing to prevent side-load bending.
Remember that only the retract end is adjustable; the extend position is fixed. After setting your depth, re-tighten the lock nut because vibration can drift an unlocked screw. Confirm your ordering essentials: 10 mm bore, 100 mm stroke, 75 mm window, S magnet, and mounting accessories.
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 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 PBJ10X100-75S FAQ
The effective stroke range is 25-100 mm. Force equals a standard PB 10 mm cylinder: 39.3 N push and 33 N pull at 0.5 MPa; 55.0 N push and 46.2 N pull at the 0.7 MPa maximum. Adjusting the stroke does not alter these force outputs.
The rear screw (M4x0.7) shortens only the retract end, while the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain PB-type cylinder does not hold position on air loss; the piston drifts, so you need an external stop or rod lock for fail-safe holding.
