The AirTAC Airtac PB Pen-type Cylinder PB12X30SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 30mm 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.
The AirTAC PB12X30SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 12mm bore and a 30mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This specific configuration includes a built-in piston magnet (-S) for position sensing and a U-type back cover that provides a 90-degree side air inlet for flat plumbing. Operating at speeds from 50-800 mm/s, it uses an M5x0.8 port and a fixed TPU bumper at each end to decelerate the stroke. The Ø5 mm rod utilizes an M10x1.0 rod-end thread for secure load coupling.

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.
| 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.

Actuates a routing blade or clamp on an electronics assembly line, utilizing the 90-degree side inlet to keep pneumatic plumbing flush against the machine frame.
Tucks cardboard flaps on a packaging conveyor, where the fixed TPU bumper adequately absorbs the impact of the 30mm stroke at moderate cycling speeds.
Drives a micro-pipette or valve block in a wet laboratory environment, benefiting from the SUS304 stainless construction to resist mild chemical corrosion.
When sizing this actuator, stepping down to a Ø10 bore yields 39.3 N of push force at 0.5 MPa, while stepping up to a Ø16 bore provides 100.5 N. For real-world work, plan for approximately 34 N of usable thrust at 0.5 MPa, which accounts for seal friction and smooth travel. Keep the thin Ø5 mm rod coaxial to prevent side-loading, as it is designed strictly for thrust. Confirm your ordering essentials: 12mm bore, 30mm stroke, M5x0.8 port, -S magnet, and U 90-degree side inlet. Note that a plain PB cylinder will drift and cannot hold a load if air pressure is lost; applying an external rod lock is necessary for fail-safe positioning.
Quick checklist
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.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of the stroke and does not function as a locking brake. An external stop or rod lock must be fitted for fail-safe load holding.
