Airtac PB Pen-type Cylinder PB12X75R
The AirTAC Airtac PB Pen-type Cylinder PB12X75R 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 PB12X75R
The AirTAC PB12X75R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight. Delivering 56.5 N of push force at 0.5 MPa, it integrates an R axial air inlet for straightforward in-line plumbing.
This 12 mm bore model uses an M5x0.8 port and an M10x1.0 rod-end thread to drive a 5 mm piston rod. Travel is governed by a fixed TPU bumper at each end rather than an adjustable air cushion, decelerating the payload smoothly over the final few millimeters. For buyers planning real work, targeting a safe working load of roughly 34 N (about 60 percent of the 0.5 MPa theoretical output) ensures smooth travel after accounting 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 PB12X75R Is Used
PCB Depaneling Jigs
Drives a small cutting blade or separator pin in electronics assembly, utilizing the slim stainless body to fit within dense routing machinery.
Carton Flap Folding
Extends 75 mm to tuck minor flaps on compact packaging lines, where the fixed TPU bumper absorbs the end-of-stroke impact without requiring adjustment.
Lab Sample Dispensing
Moves a pipette or sampling probe in analytical instruments, benefiting from the 50-800 mm/s speed range and resistance to mildly humid environments.
Is the Airtac PB Pen-type Cylinder PB12X75R the Right Cylinder?
When sizing this actuator, consider stepping down to the 10 mm bore if your payload is lighter, which provides 39.3 N of push at 0.5 MPa. If your application demands more thrust, the 16 mm bore offers 100.5 N at the same pressure. Keep in mind that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. For fail-safe holding, an external rod lock or mechanical stop is required.
To finalize your order, confirm the 12 mm bore, 75 mm stroke, M5x0.8 porting, and the R axial inlet configuration. This specific unit ships without a sensor magnet, so position detection is not supported unless specified otherwise. Because the 5 mm rod is designed for coaxial thrust, add an external linear bearing if your jig imposes any side load over the 75 mm travel.
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 PB12X75R 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.
The R designation means it uses an axial air inlet for direct in-line plumbing along the cylinder axis. Instead of an adjustable air cushion, it relies on a fixed TPU bumper at each end to decelerate the piston over the last few millimeters. If moving real tooling mass at higher speeds, you should meter-out the exhaust or add an external shock absorber.
