The AirTAC Airtac PB Pen-type Cylinder PB12X150CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 150mm 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 PB12X150CB is a double-acting JIS pen-size mini cylinder engineered for compact automation. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless barrel and a Ø5 mm rod. Plumbing is via an M5x0.8 port, while the rod-end features an M10x1.0 thread for secure load coupling.
This 150 mm stroke variant includes a CB double clevis back cover, allowing the body to pivot smoothly on articulated linkages. The fixed TPU bumper at each end absorbs end-of-stroke impact, and because the rod is only Ø5 mm, maintaining coaxial thrust over the long travel is critical to prevent side-loading wear.

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.

Ideal for swinging a lightweight sorting flap on a packaging conveyor, utilizing the CB double clevis to accommodate the articulating pivot motion.
Drives a delicate probe carrier over the 150 mm travel to contact test points on large circuit boards without overwhelming the board surface.
Pushes small molded plastic parts out of an injection mold cavity, relying on the bumper to soften the ejection stroke at high cycle rates.
When sizing this actuator, stepping down to a Ø10 bore yields 39.3 N push at 0.5 MPa, while stepping up to a Ø16 bore provides 100.5 N. Confirm your ordering essentials: 12 mm bore, 150 mm stroke, M5x0.8 port, CB double clevis, and no sensor magnet.
Note that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your process requires fail-safe load holding, you must integrate an external stop or rod lock. Furthermore, over this 150 mm travel, the slender Ø5 mm rod needs an external guide or linear bearing if subjected to any off-axis forces.
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, push is 79.1 N and pull is 65.4 N. Operating pressure ranges from 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The CB back cover provides a double clevis joint for pivoting mounts. The cylinder uses fixed TPU bumpers at both ends which decelerate the piston over the last few millimeters; they are not adjustable, so for heavy tooling mass at high speeds, meter-out the exhaust or add an external shock absorber.
