Airtac PB Pen-type Cylinder PB12X160SU
The AirTAC Airtac PB Pen-type Cylinder PB12X160SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 160mm 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 PB12X160SU
The AirTAC PB12X160SU is a double-acting JIS pen-size mini cylinder engineered for compact automation. It generates 56.5 N of push force at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to resist moisture in damp production zones. The U suffix equips the rear cover with a 90-degree side air inlet, allowing flat plumbing against machine frames.
Driven through an M5x0.8 port, this unit travels a 160 mm stroke at speeds from 50-800 mm/s. It relies on a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because the 160 mm length is substantial for a Ø5 mm rod, maintaining coaxial thrust is critical to prevent deflection during extension.

| Model | Airtac PB Pen-type Cylinder PB12X160SU |
|---|---|
| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 160 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 300 mm |
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 PB12X160SU Is Used
PCB Depaneling Router
Pushes a carrier plate into the cutting zone on a depaneling machine, where the stainless barrel withstands fiberglass dust and the U inlet keeps airlines flush.
Carton Flap Folder
Extends 160 mm to tuck minor flaps on a packing line, using the fixed TPU bumper to soften the impact at the end of each high-speed cycle.
Test Fixture Actuation
Moves a probe block into position for electronic testing, relying on the S magnet to trigger a solid-state switch and confirm the 160 mm extension.
Is the Airtac PB Pen-type Cylinder PB12X160SU the Right Cylinder?
When sizing this 12 mm bore unit, consider stepping down to the Ø10 model if your load is lighter, which provides 39.3 N push at 0.5 MPa. If you need more power, the Ø16 bore yields 100.5 N push at 0.5 MPa.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumper only decelerates near stroke end and does not act as a lock. For position holding, specify an external rod lock. To finalize your order, confirm the 12 mm bore, 160 mm stroke, M5x0.8 port, built-in S magnet for reed or electronic switches, and the U 90-degree side inlet.
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 PB12X160SU FAQ
This 12 mm bore cylinder delivers 56.5 N push and 46.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it outputs 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not function as a brake. You must add an external rod lock or mechanical stop to hold a suspended load safely.
