Airtac PB Pen-type Cylinder PB16X240SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X240SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 240mm 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 PB16X240SCB
The AirTAC PB16X240SCB 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 end-of-arm tooling payloads low. Delivering 100.5 N of push force at 0.5 MPa, this model includes a built-in piston magnet for position sensing and a CB double clevis back cover for pivoting loads.
Air enters via an M5x0.8 port, and the rod end features an M10x1.0 thread for secure load coupling. Because the stroke extends to 240 mm, the slender Ø5 mm piston rod requires strict coaxial alignment; adding an external linear bearing prevents side-load binding. The end caps integrate a fixed TPU bumper to decelerate the piston near stroke limits, though external shock absorption is advised when moving heavy tooling at high speeds.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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 PB16X240SCB Is Used
PCB Depaneling Router
Actuates a pivoting cutting head on an automated router, utilizing the CB double clevis to maintain smooth angular alignment while separating printed circuit boards.
Pouch Sealing Clamp
Closes a pivoting sealing jaw on a vertical form-fill-seal machine, where the compact stainless body resists washdown moisture and the 240 mm stroke accommodates tall pouch formats.
Package Diverter Arm
Swings a lightweight routing flap on a logistics sorting line, relying on the built-in magnet to confirm arm position and the TPU bumper to soften end-of-stroke impact.
Is the Airtac PB Pen-type Cylinder PB16X240SCB the Right Cylinder?
Selecting this 16 mm bore actuator provides 100.5 N push and 90.7 N pull at 0.5 MPa. If your application requires less force, the adjacent 12 mm bore outputs 56.5 N push at 0.5 MPa; stepping up is not applicable as 16 mm is the largest in this series. For real-world sizing, plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical push) to account for seal friction, which equates to lifting approximately 5.1 kg vertically with a 2:1 safety margin.
This specific configuration includes the S magnet for use with AirTAC reed or electronic switches, and the CB double clevis for pivoting mountings. Note that a plain PB cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required to hold a load safely. Confirm your ordering essentials: 16 mm bore, 240 mm stroke, M5x0.8 port, magnet, and clevis bracket.
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 PB16X240SCB FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The CB back cover is a double clevis designed for pivoting loads that require angular movement. The cylinder uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel; it is not adjustable, so metering out the exhaust or adding an external shock absorber is recommended for high-speed operations.
