Airtac PB Pen-type Cylinder PB12X150SR
The AirTAC Airtac PB Pen-type Cylinder PB12X150SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 150mm 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 PB12X150SR
The AirTAC PB12X150SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It provides a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa, driven through an M5x0.8 port and a sturdy M10x1.0 rod-end thread. The slim SUS304 stainless barrel and piston rod excel in damp or mildly corrosive environments, saving valuable space and payload on light end-of-arm tooling.
This 150 mm stroke variant includes an integrated piston magnet (-S) for position sensing using AirTAC reed or electronic switches, paired with an R axial inlet for clean in-line plumbing. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion.

| 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 |

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 PB12X150SR Is Used
PCB Depaneling Router
Extends a guide pin on an electronic board routing fixture, utilizing the 56.5 N push force and S magnet to confirm reach before the cutting spindle engages.
Blister Pack Feeder
Indexes thin plastic blister cavities into a sealing press, where the slim 12 mm pen-size body avoids obstructing the web path and the R inlet keeps plumbing flat.
Lab Sample Divertor
Pushes a deflector flap to route liquid vials on a diagnostic analyzer, benefiting from the SUS304 construction in humid environments and the 150 mm travel distance.
Is the Airtac PB Pen-type Cylinder PB12X150SR the Right Cylinder?
When sizing this 12 mm bore 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, letting you tune the force exactly to the payload. Because this model uses a 150 mm stroke, the slender Ø5 mm rod requires an external guide or linear bearing if subjected to any off-axis loads to prevent binding. To confirm your ordering essentials: check the 12 mm bore, 150 mm stroke, M5x0.8 porting, S magnet, and R axial back cover. Note that a standard PB body does not hold its position if air pressure is lost or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding.
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 PB12X150SR 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 is 79.1 N and the pull is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end; it does not act as a lock. An external stop or rod lock is required for fail-safe load holding.
