Airtac PB Pen-type Cylinder PB12X165SU
The AirTAC Airtac PB Pen-type Cylinder PB12X165SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 165mm 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 PB12X165SU
The AirTAC PB12X165SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 12mm bore and a 165mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide corrosion resistance for damp production areas while keeping end-of-arm tooling exceptionally light.
This configuration includes a built-in piston magnet (-S) for position sensing using AirTAC reed or electronic switches, and a U-type back cover offering a 90-degree side air inlet for flat plumbing along the actuator body. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling. End-of-stroke energy is managed by a fixed TPU bumper at each end, which decelerates the piston over the final few millimeters rather than providing a locking brake.

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 PB12X165SU Is Used
PCB Depaneling Router
Extends a light cutting probe along a 165mm path to singulate circuit boards, utilizing the 90-degree side inlet to keep pneumatic tubing flush against the moving carriage.
Blister Pack Sorting
Pushes pharmaceutical blister packs into secondary cartoning chutes at high frequency, where the SUS304 body withstands routine washdowns and the magnetic sensor verifies part ejection.
Micro-Component Tray Loading
Transfers delicate surface-mount components across pick-and-place machinery, relying on the fixed TPU bumpers to soften end-of-stroke impacts without requiring bulky external cushioning.
Is the Airtac PB Pen-type Cylinder PB12X165SU the Right Cylinder?
If you need slightly less force, the neighbouring 10mm bore provides 39.3 N push at 0.5 MPa; stepping up to the 16mm bore yields 100.5 N push for heavier tooling. Because the 165mm stroke is relatively long for the slender Ø5 mm rod, always use an external guide or linear bearing to prevent side-load binding. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required to hold a load securely in place. Confirm your ordering essentials: 12mm bore, 165mm stroke, M5x0.8 port, S magnet, U side-inlet cover, and any LB, FA, or CJ mounting brackets.
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 PB12X165SU FAQ
At 0.5 MPa, this 12mm bore double-acting cylinder provides 56.5 N of push (extend) force and 46.7 N of pull (retract) force. 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 speed of 50-800 mm/s.
The PB12X165SU uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel; it is not field-adjustable, so for high-speed loads you should meter-out the exhaust or add an external shock absorber. The included -S magnet allows AirTAC reed or electronic switches to detect piston position, and the U-type back cover provides a 90-degree side inlet for flat plumbing.
