Airtac PB Pen-type Cylinder PB12X160SR
The AirTAC Airtac PB Pen-type Cylinder PB12X160SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 160mm 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 PB12X160SR
The AirTAC PB12X160SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while saving valuable space and payload on end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, it operates at speeds from 50-800 mm/s with a maximum pressure of 0.7 MPa.
This specific configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet (-S) for position detection. Because the stroke extends to 160 mm, the slender Ø5 mm rod requires careful alignment to avoid side loading; adding an external linear bearing ensures smooth coaxial thrust. The M5x0.8 port and M10x1.0 rod-end thread provide straightforward integration into tight jigs.

| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 160 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 PB12X160SR Is Used
PCB Edge Guiding
Positions delicate printed circuit boards on an SMT line using the compact 12 mm body and axial inlet to fit within dense conveyor frames.
Film Clamp Release
Actuates a small clamping jaw on a vertical form-fill-seal machine, where the 160 mm stroke provides ample extension for clearing packaging film paths.
Lab Sample Ejection
Pushes processed vial racks out of a centrifuge slot, benefiting from the SUS304 build to resist humidity and chemical exposure in laboratory settings.
Is the Airtac PB Pen-type Cylinder PB12X160SR the Right Cylinder?
When sizing this actuator, stepping down to the Ø10 bore yields 39.3 N of push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N, allowing you to tune payload capacity precisely.
Remember that a standard pen-style body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed TPU bumper only decelerates it near the end of travel. For fail-safe load holding, an external rod lock or mechanical stop is required. Confirm your ordering essentials: 12 mm bore, 160 mm stroke, M5x0.8 port, S magnet, R axial inlet, and your preferred mounting bracket.
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 PB12X160SR 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper at each end only decelerates the piston near the stroke limits; it does not act as a brake. For vertical load holding, you must install an external rod lock or mechanical stop.
