Airtac PB Pen-type Cylinder PB12X100SU
The AirTAC Airtac PB Pen-type Cylinder PB12X100SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 100mm 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 PB12X100SU
The AirTAC PB12X100SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency automation. It features a 12 mm bore and a 100 mm stroke, generating 56.5 N of push and 46.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This U variant incorporates a 90-degree side air inlet for flat plumbing, and the built-in S magnet enables position detection.
Air enters through the M5x0.8 port to drive the Ø5 mm rod at speeds from 50-800 mm/s. Instead of an adjustable air cushion, the ends feature a fixed TPU bumper that absorbs impact over the final few millimeters. Because the rod is only 5 mm thick, maintaining coaxial alignment is critical to prevent side-loading over this 100 mm extension.

| 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 PB12X100SU Is Used
Carton Flap Folder
Tucks minor flaps on small product boxes in tight packaging lines where the U side inlet keeps plumbing flat against the machine frame, saving valuable vertical space.
Lab Sample Dispenser
Actuates a small dosing valve for liquid reagents, benefiting from the SUS304 stainless construction to resist humidity and chemical vapors in analytical environments.
Is the Airtac PB Pen-type Cylinder PB12X100SU the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø10 bore if your payload is lighter, which offers 39.3 N of push at 0.5 MPa. If you need more thrust, the Ø16 bore provides 100.5 N at the same pressure. For this specific PB12X100SU configuration, confirm your requirements for the 12 mm bore, 100 mm stroke, M5x0.8 port, built-in magnet, and U 90-degree side inlet. Note that a plain cylinder like this drifts when air pressure is lost or the valve is centered; the bumper decelerates the piston near stroke end but does not function as a locking brake, so install an external rod lock if you need fail-safe position holding.
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 PB12X100SU FAQ
At 0.5 MPa, this 12 mm bore cylinder provides 56.5 N of push and 46.7 N of pull. At the maximum operating pressure of 0.7 MPa, the force increases to 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
The S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position sensing. However, the cylinder does not hold its load if air is lost; the piston will drift. An external stop or rod lock is required for fail-safe holding.
