Airtac PB Pen-type Cylinder PB16X210SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X210SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 210mm 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 PB16X210SCB
The AirTAC PB16X210SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a SUS304 stainless steel slim round barrel and piston rod, offering robust resistance in damp or mildly corrosive environments while keeping end-of-arm tooling exceptionally light. Delivering 100.5 N of push force at 0.5 MPa, this model integrates 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, driving the Ø5 mm rod at speeds from 50 to 800 mm/s. End-of-stroke deceleration relies on fixed TPU bumpers rather than adjustable air cushions. Because the rod is only 5 mm thick, maintaining coaxial alignment over the 210 mm stroke is critical to prevent side-load wear; adding an external linear bearing ensures smooth thrust transmission.

| Stroke | 210 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 |

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 PB16X210SCB Is Used
PCB Depaneling Router
Actuates a pivoting cutting head on an automated router, utilizing the CB double clevis to accommodate angular movement while routing precise outlines on assembled circuit boards.
Pouch Sealing Clamp
Cycles a high-speed sealing bar on a vertical form-fill-seal machine, where the compact pen-size body saves space and the integrated magnet confirms the closed position via a reed or electronic switch.
Sorter Diverter Arm
Pushes lightweight packages off a main conveyor belt at high frequency, relying on the stainless build to withstand washdown cycles in a food packaging facility.
Is the Airtac PB Pen-type Cylinder PB16X210SCB the Right Cylinder?
Selecting this 16 mm bore provides the highest standard thrust in the PB family, pushing 100.5 N at 0.5 MPa. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push, making the 16 mm variant the definitive choice for heavier small-part handling. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
When sizing vertical lifts, this actuator can manage approximately 5.1 kg against gravity using a sane 2:1 safety margin. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates impact near stroke end, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16 mm bore, 210 mm stroke, M5x0.8 port, S magnet, CB double clevis.
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 PB16X210SCB FAQ
At 0.5 MPa, this 16 mm bore cylinder provides 100.5 N push and 90.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s, with a proof pressure of 1.2 MPa.
It uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters, which are not field-adjustable; for high mass or speed, add an external shock absorber. It does not hold its position if air is lost, so an external rod lock is needed for fail-safe load holding.
