Airtac PB Pen-type Cylinder PB12X75SR
The AirTAC Airtac PB Pen-type Cylinder PB12X75SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 75mm 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 PB12X75SR
The AirTAC PB12X75SR is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa, driven through an M5x0.8 air port. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp production zones while keeping weight low for end-of-arm tooling. This 75 mm stroke variant uses an R axial inlet for in-line plumbing.
Equipped with a built-in piston magnet (-S), the unit supports AirTAC reed or electronic switches for precise position detection. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs impact over the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber. Plan for a safe working load of roughly 34 N at 0.5 MPa to account for seal friction.

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 PB12X75SR Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics depaneling machine, utilizing the slim stainless body to fit within dense routing fixtures.
Blister Pack Sealing
Provides the 56.5 N clamping thrust at 0.5 MPa to press film layers together in a medical blister packaging station.
Lab Tube Ejection
Pushes filled centrifuge tubes out of a sorting carousel, where the compact 75 mm stroke and axial inlet keep the automation footprint minimal.
Is the Airtac PB Pen-type Cylinder PB12X75SR the Right Cylinder?
This 12 mm bore generates 56.5 N of push at 0.5 MPa. If your application requires less force, stepping down to the 10 mm bore yields 39.3 N; if you need more thrust, the 16 mm bore provides 100.5 N. When sizing vertical lifts, expect to handle about 2.9 kg safely with a 2:1 margin. Note that a standard PB cylinder does not hold position if air pressure drops or the valve centers, so incorporate an external rod lock for fail-safe holding. To order, confirm the 12 mm bore, 75 mm stroke, M5x0.8 port, -S magnet, and R axial inlet configuration.
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 PB12X75SR 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.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not act as a lock. For vertical loads, you must add an external rod lock or mechanical stop.
