Airtac PB Pen-type Cylinder PB12X10SR
The AirTAC Airtac PB Pen-type Cylinder PB12X10SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 10mm 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 PB12X10SR
The AirTAC PB12X10SR is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It delivers a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa from a 12 mm bore. The SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments, while the slim round profile saves payload on light end-of-arm tooling.
This specific configuration includes an R axial air inlet for in-line plumbing and a built-in S magnet for position sensing. Air enters via an M5x0.8 port, and the M10x1.0 rod-end thread secures your load coupling. With a 10 mm stroke, it cycles rapidly; the fixed TPU bumper at each end decelerates the piston near the stroke limits, though external shock absorption is advised if moving heavy tooling at high speeds.

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 PB12X10SR Is Used
Blister Pack Sealing
Cycles a small heated head down onto pharmaceutical blister packs, where the compact stainless body resists humidity and the R axial inlet keeps plumbing flat against the machine frame.
Micro-Clamp Actuation
Drives a delicate clamping finger in semiconductor pick-and-place handlers, using the S magnet to trigger an electronic switch for precise end-of-stroke confirmation.
Is the Airtac PB Pen-type Cylinder PB12X10SR the Right Cylinder?
When sizing this actuator, stepping down to the 10 mm bore yields 39.3 N of push at 0.5 MPa, whereas stepping up to the 16 mm bore provides 100.5 N.
Because the 5 mm rod is designed strictly for coaxial thrust, avoid side loads and add an external linear guide if your jig imposes off-axis forces. Note that a standard PB body does not hold its position if air pressure drops or the valve centers; the piston will drift, so an external rod lock is required for fail-safe holding. To finalize your order, confirm the 12 mm bore, 10 mm stroke, M5x0.8 port, S magnet, and R axial inlet.
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 PB12X10SR FAQ
The 12 mm bore generates a push of 56.5 N and a pull of 46.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, push increases to 79.1 N and pull to 65.4 N. Operating pressure ranges from 0.15 to 0.7 MPa, with a speed of 50-800 mm/s.
It uses a fixed TPU bumper at both ends to decelerate the piston over the last few millimeters; this is not an adjustable air cushion, so meter-out the exhaust if cycling fast with real mass. The included S magnet allows AirTAC reed or electronic switches to read piston position.
