Airtac PB Pen-type Cylinder PB16X25SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X25SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 25mm 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 PB16X25SCB
The AirTAC PB16X25SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a SUS304 stainless steel piston rod and slim round barrel, offering robust resistance in damp or mildly corrosive environments without adding bulk. Delivering 100.5 N of push force at 0.5 MPa, it provides the highest thrust in the PB family while maintaining a lightweight profile ideal for tight jigs and end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position sensing and a CB double clevis back cover for pivoting loads. Air plumbing connects via an M5x0.8 port. The unit relies on a fixed TPU bumper at each end to decelerate the stroke, and the Ø5 mm rod is designed for pure coaxial thrust rather than side loading.

| Stroke | 25 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 PB16X25SCB Is Used
Pivot-Actuated Clamping Arm
Drives a short-throw pivoting clamp on a CNC fixture, utilizing the CB double clevis to accommodate the swing arc while holding light aluminum workpieces.
Carton Flap Folder
Folds small corrugated carton flaps on a packaging line, where the 100.5 N extend force easily overcomes board stiffness and the SUS304 barrel resists humid washdowns.
Electronic Component Aligner
Pushes PCBs into alignment on a conveyor reflow station, using the S magnet with an electronic switch to confirm the 25mm extend position for high-speed cycling.
Is the Airtac PB Pen-type Cylinder PB16X25SCB the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N, which reflects a practical 60% margin of the 100.5 N theoretical push at 0.5 MPa to account for seal friction. If your application requires less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; since Ø16 is the largest in this series, stepping up requires migrating to a different body family. For vertical lifts, this model can safely handle parts weighing roughly 5.1 kg when applying a sane 2:1 safety margin.
Because the CB double clevis allows pivoting, ensure the mount absorbs lateral play. A plain PB cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required if you need fail-safe position holding. Confirm your ordering essentials: 16mm bore, 25mm stroke, M5x0.8 port, S magnet, CB clevis, and any LB, FA, or CJ brackets.
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 PB16X25SCB FAQ
At 0.5 MPa this 16mm 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.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so high-speed tooling may require metering the exhaust or adding an external shock. The S designation means it has a built-in magnet compatible with AirTAC reed or electronic switches.
