Airtac PB Pen-type Cylinder PB12X120SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X120SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 120mm 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 PB12X120SCB
The AirTAC PB12X120SCB is a double-acting JIS pen-size mini cylinder engineered for compact automation. It generates 56.5 N of push force and 46.7 N of pull force at 0.5 MPa, utilizing a 12 mm bore and 120 mm stroke. The SUS304 stainless steel barrel and piston rod provide reliable durability in damp or mildly corrosive environments, while the slim round profile saves valuable space on tight jigs and lightweight end-of-arm tooling.
This configuration includes a built-in piston magnet (S) for position sensing using AirTAC reed or electronic switches, and a CB double clevis back cover for pivoting loads. Pneumatic connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread. Travel speed reaches 50-800 mm/s, with fixed TPU bumpers at both ends to absorb end-of-stroke impact.

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 PB12X120SCB Is Used
PCB Depaneling Router
Actuates a pivoting cutting head on an automated router, utilizing the CB double clevis to accommodate the arc motion while separating printed circuit boards.
Pouch Sealing Clamp
Cycles a lightweight sealing jaw at high frequency on a vertical form-fill-seal machine, relying on the 56.5 N extend force to close the heat element.
Pick-and-Place Ejector
Pushes small electronic components out of a vacuum nozzle fixture on a pick-and-place robot, where the slim 12 mm barrel minimizes interference with adjacent tooling.
Is the Airtac PB Pen-type Cylinder PB12X120SCB the Right Cylinder?
When sizing this 12 mm bore model, stepping down to a 10 mm bore yields 39.3 N of push force at 0.5 MPa, while stepping up to a 16 mm bore provides 100.5 N. This PB12X120SCB variant is specified with a 120 mm stroke, an S magnet for sensing, and a CB double clevis mount. Note that a plain pen-size cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper decelerates the piston near the end of travel but does not function as a locking brake. If your application requires fail-safe position holding, incorporate an external stop or rod lock.
Because the 5 mm piston rod is designed primarily for coaxial thrust, avoid subjecting it to lateral side loads, especially over the 120 mm stroke length. Adding an external guide or linear bearing will prevent rod binding and premature seal wear. Confirm your ordering essentials match the required bore, stroke, M5x0.8 porting, and the desired CB clevis pivot geometry.
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 PB12X120SCB FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. 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 proof pressure of 1.2 MPa. The operating speed ranges from 50-800 mm/s.
This cylinder uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters of travel; they are not adjustable, so metering out the exhaust or adding external shock absorbers is recommended for high-speed or high-mass loads. The built-in S magnet allows you to mount AirTAC reed or electronic switches directly onto the body for precise position detection.
