Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-50 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 175mm stroke with a 50mm fine-adjustable window — settable from 125 to 175mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-50
The AirTAC PBJ10X175-50 is a double-acting, single-rod pen-size mini cylinder featuring a 50mm adjustable stroke window. A rear adjuster screw (M4x0.7) shortens the retract end, giving an effective stroke range of 125mm to 175mm. The extend end remains fixed. Output force equals a standard PB of identical bore, providing 39.3N push and 33N pull at 0.5MPa. The M5x0.8 air port and fixed TPU bumper are standard.
This configuration uses a 175mm stroke, which exceeds the 100mm max standard for this 10mm bore, making it a made-to-order part. The Ø4mm stainless rod is built for coaxial thrust; over this extended length, add an external guide to prevent side-load wear. Plan for a safe working load of about 24N (roughly 60% of the 0.5MPa push force) or a vertical lift of 2kg with a 2:1 margin. Re-tighten the lock nut after setting to prevent vibration drift.

| Nominal stroke | 175 mm |
| Adjustable window | 50 mm (125–175 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) |

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 PBJ10X175-50 Is Used
Changeover Fixtures
Dial in the exact retract stop during product changeovers without machining new hard stops or re-ordering cylinders.
Trial Insertion Stops
Set variable insertion depths on prototype tooling by tweaking the rear screw, locking the nut once the perfect position is found.
Alignment Arms
Fine-tune the pull-back distance of delicate positioning arms in tight jigs, relying on the SUS304 slim body to save space.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X175-50 the Right Cylinder?
For sizing context, stepping up to the 12mm bore yields 56.5N push at 0.5MPa, while dropping below 10mm reduces force further. This 10mm bore provides 39.3N push at 0.5MPa and 55N at the 0.7MPa maximum. Remember that only the retract position is field-adjustable; the extend stop is fixed. Confirm your ordering essentials: bore, 175mm nominal stroke, 50mm window, no magnet, and mounting choice. Because the fixed TPU bumper only decelerates the last few mm, meter-out the exhaust or add an external shock absorber when moving real tooling mass at mid-to-high speed.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 125–175 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 PBJ10X175-50 FAQ
The effective stroke range is 125mm to 175mm (nominal 175 minus the 50mm window). Force is unchanged from a standard PB 10mm bore: 39.3N push and 33N pull at 0.5MPa, rising to 55N push and 46.2N pull at the 0.7MPa maximum operating pressure.
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. A plain cylinder does not hold position on air loss, so add an external stop or rod lock for fail-safe load holding.
