The AirTAC Airtac PB Pen-type Cylinder PB12X15SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 15mm 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 PB12X15SU is a JIS pen-size double-acting single-rod mini cylinder engineered for high-frequency small-part motion. It features a 12mm bore and a 15mm stroke, delivering 56.5N of push force and 46.7N of pull force at 0.5MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping end-of-arm tooling lightweight.
This variant includes a built-in piston magnet (-S) for position sensing with AirTAC reed or electronic switches, and a U-type back cover providing a 90-degree side air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. It relies on a fixed TPU bumper at each end to decelerate the stroke, and the Ø5mm rod is designed for pure coaxial thrust.

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.

Provides consistent downward pressure on a heat-sealing head, where the 90-degree side inlet keeps plumbing flush against the flat machine frame.
Toggles a precision needle valve for adhesive dosing, using the built-in magnet to confirm closed positions via an electronic switch.
When sizing this 12mm bore actuator, consider stepping down to the 10mm bore (39.3N push at 0.5MPa) for lighter tasks, or up to the 16mm bore (100.5N push at 0.5MPa) if you need greater thrust.
Because the fixed TPU bumper only absorbs impact over the final few millimeters, metering out the exhaust is recommended if moving real tooling mass at higher speeds. Note that a plain cylinder like this drifts when air pressure is lost or the valve is centered; an external rod lock is required for fail-safe load holding. Confirm your ordering essentials: 12mm bore, 15mm stroke, M5x0.8 port, S magnet, and U side inlet.
Quick checklist
At 0.5MPa, the push force is 56.5N and the pull force is 46.7N. At the maximum operating pressure of 0.7MPa, the push force is 79.1N and the pull force is 65.4N. The operating pressure range is 0.15-0.7MPa, with a speed of 50-800mm/s.
No, a plain PB cylinder will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the piston near the stroke ends and do not act as a brake. You must add an external rod lock or mechanical stop for fail-safe load holding.
