Airtac PB Pen-type Cylinder PB12X35CB
The AirTAC Airtac PB Pen-type Cylinder PB12X35CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 35mm 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 PB12X35CB
The AirTAC PB12X35CB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 5 mm rod to endure mildly damp or corrosive production zones. The M5x0.8 air ports keep plumbing standardized across the Ø6-Ø16 family.
This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly during articulation. Because it lacks an adjustable air cushion, the ends rely on a fixed TPU bumper that absorbs impact over the final few millimeters. If your tooling mass is high at cycle speed, metering out the exhaust or fitting an external shock absorber will prevent the bumper from bottoming out.

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 PB12X35CB Is Used
PCB Depanelling Arms
Pivots a routing head to singulate printed circuit boards, using the CB clevis to maintain angular alignment while exerting 56.5 N of extension force.
Pouch Sealing Jaws
Closes lightweight sealing bars on vertical form-fill machines, where the fixed TPU bumper softens the impact of the 35 mm stroke at high cyclic speeds.
Diverter Flap Actuation
Swings a sorting gate along a packaging line, leveraging the double-clevis mount to accommodate the arc of the pivoting flap mechanism.
Is the Airtac PB Pen-type Cylinder PB12X35CB the Right Cylinder?
If you need less force, the 10 mm bore provides 39.3 N of push at 0.5 MPa; stepping up to the 16 mm bore yields 100.5 N for heavier tooling. Note that a plain PB body will drift and cannot hold a load if air pressure drops or the valve is centered—always add an external rod lock for fail-safe positioning.
To order, confirm the 12 mm bore, 35 mm stroke, M5x0.8 porting, and the CB double clevis bracket. This unit ships without a sensor magnet; if you need position feedback, specify the -S option for reed or electronic switch compatibility. The slender 5 mm rod is built for coaxial thrust, so guide any off-axis loads externally to prevent side-loading damage.
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 PB12X35CB FAQ
At 0.5 MPa this 12 mm bore cylinder outputs 56.5 N of push and 46.7 N of pull. At the maximum operating pressure of 0.7 MPa, the push increases to 79.1 N and the pull to 65.4 N. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, the piston will drift if air is removed or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not function as a locking brake. You must install an external rod lock or mechanical stop to safely hold a suspended load.
