Airtac PB Pen-type Cylinder PB12X15SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X15SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 15mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB12X15SCB
The AirTAC PB12X15SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, it integrates a built-in magnet for position sensing.
This specific configuration includes a CB double clevis back cover for pivoting loads and an S option magnet compatible with AirTAC reed or electronic switches. The M5x0.8 port and M10x1.0 rod-end thread streamline plumbing and load coupling. It relies on a fixed TPU bumper at each end for end-of-stroke deceleration, and the Ø5 mm rod is designed for pure coaxial thrust.

| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| 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) |

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB12X15SCB Is Used
Pivoting Component Ejection
Ideal for swinging small stamped electronics parts out of a press using the CB double clevis, applying a safe 34 N working load to clear the die area rapidly.
PCB Test Fixture Clamping
The slim pen-size body fits between dense circuit board test probes, using the S magnet to confirm clamp position before electrical continuity checks begin.
Flap Deflection Mechanism
Suitable for lightweight packaging machines where the cylinder pivots a guide flap, relying on the SUS304 build to withstand occasional washdown without corroding.
Is the Airtac PB Pen-type Cylinder PB12X15SCB the Right Cylinder?
If you need to step down, the Ø10 bore provides 39.3 N push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. This 15 mm stroke model with a CB clevis is ideal for pivoting mechanisms, but remember a plain PB cylinder drifts when air is lost—add an external rod lock if you need fail-safe position holding.
Confirm your ordering essentials: 12 mm bore, 15 mm stroke, M5x0.8 air port, S magnet for sensing, and CB double clevis mount. Because the fixed TPU bumper only decelerates the last few millimeters, meter-out the exhaust or add an external shock absorber if moving real tooling mass at high speed.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ 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 Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB12X15SCB FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
No, a plain PB-type cylinder does not hold its load on air loss or when the valve is centred; the piston will drift. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a lock. An external stop or rod lock is required for fail-safe holding.
