Airtac PB Pen-type Cylinder PB12X60SR
The AirTAC Airtac PB Pen-type Cylinder PB12X60SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 60mm 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 PB12X60SR
The AirTAC PB12X60SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering reliable durability in damp or mildly corrosive environments. 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 unit uses a fixed TPU bumper at each end to decelerate the stroke over the final few millimeters. Because it carries the -S option, a built-in piston magnet allows position detection using AirTAC reed or electronic switches. The Ø5 mm rod provides coaxial thrust, and the M5x0.8 port matches the standard bore mapping.

| Rod diameter | Ø5 mm |
| Stroke | 60 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 |

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 PB12X60SR Is Used
PCB Depaneling Jig
Actuates a routing blade in tight electronics assembly cells where the slim stainless body resists flux humidity and fits between dense conveyor lines.
Clamshell Carton Flap
Tucks small flaps on pharmaceutical packaging machines, using the 56.5 N thrust to cleanly fold light cardboard without crushing the product.
Lab Dispenser Positioning
Moves a micro-valve head over reagent trays, benefiting from the 60 mm stroke and position feedback via the built-in S magnet and electronic switches.
Is the Airtac PB Pen-type Cylinder PB12X60SR the Right Cylinder?
When sizing this actuator, stepping down to the Ø10 bore yields 39.3 N push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N. For real-world work at 0.5 MPa, plan for a safe working load of roughly 34 N to account for seal friction. This equates to lifting about 2.9 kg vertically with a sane 2:1 margin.
Note that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 12 mm bore, 60 mm stroke, M5x0.8 port, S magnet, R axial inlet, and no 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 PB12X60SR FAQ
At 0.5 MPa this 12 mm bore cylinder provides 56.5 N push and 46.7 N pull. At the maximum operating pressure of 0.7 MPa, it provides 79.1 N push and 65.4 N pull. Operating pressure ranges from 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 stroke near the end caps and does not act as a brake. For vertical loads, you must add an external guide to protect the Ø5 mm rod from side load, and a separate rod lock for fail-safe holding.
