Airtac PB Pen-type Cylinder PB12X160CB
The AirTAC Airtac PB Pen-type Cylinder PB12X160CB 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 PB12X160CB
The AirTAC PB12X160CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit is threaded with an M10x1.0 rod end and utilizes an M5x0.8 air port.
This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin to accommodate lateral movement during the stroke. Travel spans 160 mm, and impact at the endpoints is managed by a fixed TPU bumper at each end rather than an adjustable air cushion.

| 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 |

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 PB12X160CB Is Used
PCB Depaneling Router
Pivots a cutting tool guide arm via the CB clevis to track along V-scored circuit boards, utilizing the 160 mm travel to span large panels.
Sorting Diverter Arm
Swings a lightweight paddle at a packaging junction to route small cartons, relying on the stainless build to resist washdown moisture.
Lab Sample Indexing
Advances a test tube rack carriage through a 160 mm cycle, where the fixed TPU bumpers provide consistent endpoint deceleration without requiring manual adjustment.
Is the Airtac PB Pen-type Cylinder PB12X160CB the Right Cylinder?
When sizing this actuator, consider stepping to the 10 mm bore if your payload is lighter, which provides 39.3 N of push at 0.5 MPa. If your application demands more thrust, the 16 mm bore offers 100.5 N at the same pressure. For this 160 mm stroke, the Ø5 mm piston rod is built for coaxial thrust; over extended reaches or with off-axis loads, adding an external guide or linear bearing prevents rod binding.
Because this is a double-acting cylinder, a plain PB body does not hold its position if air pressure is lost or the valve is centered—the piston will drift. For fail-safe load holding, an external stop or rod lock is required. To order, confirm your essentials: 12 mm bore, 160 mm stroke, M5x0.8 porting, CB double clevis back cover, and no sensor magnet.
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 PB12X160CB FAQ
This 12 mm bore double-acting cylinder provides 56.5 N push and 46.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a plain double-acting cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke endpoints and does not act as a lock or brake. An external rod lock or mechanical stop is required to safely hold a load.
