Airtac PB Pen-type Cylinder PB16X5R
The AirTAC Airtac PB Pen-type Cylinder PB16X5R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 5mm 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 PB16X5R
The AirTAC PB16X5R is a JIS pen-size double-acting mini cylinder engineered for very short 5 mm movements. It delivers 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and a Ø5 mm piston rod threaded M10x1.0. The R designation signifies an axial air inlet, keeping your in-line plumbing perfectly straight against the back cover.
Air enters via an M5x0.8 port to drive the piston at speeds between 50 and 800 mm/s. End-of-travel deceleration relies on a fixed TPU bumper rather than an adjustable air cushion, which is standard for this compact class. This specific 5 mm stroke variant excels in tight clamping jaws where only a few millimeters of precise thrust are required.

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 PB16X5R Is Used
Micro-Clamping Jaws
Provides a rapid 5 mm thrust for gripping small electronic components in automated printed circuit board assembly fixtures.
Film Seal Snipping
Cycles a short shear blade to cut packaging webs cleanly in continuous flow wrapping machinery.
Part Ejection Pins
Kicks lightweight molded plastic parts out of a forming die using a compact, high-force burst of linear motion.
Is the Airtac PB Pen-type Cylinder PB16X5R the Right Cylinder?
Choosing this 16 mm bore provides the highest standard force in the PB family, stepping up considerably from the 12 mm bore which offers 56.5 N of push at 0.5 MPa. If your application demands even more power, a larger profile body would be necessary since 16 mm is the maximum diameter available in this series. When sizing your motion, plan for a safe working load of about 60 N, which accounts for roughly 60 percent of the 100.5 N theoretical push at 0.5 MPa to overcome seal friction and ensure smooth travel.
For vertical lifting tasks, this actuator can safely handle approximately 5.1 kg when applying a sensible 2:1 safety margin against gravity. Keep in mind that a plain double-acting cylinder drifts when air pressure is removed or the valve is centered, so an external rod lock is required for fail-safe holding. To order, confirm the 16 mm bore, 5 mm stroke, M5x0.8 porting, and the R axial inlet configuration.
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 PB16X5R 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 is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the final few millimeters, which is not adjustable or field-tunable. The cylinder does not hold its position if air is lost, so an external stop is needed for fail-safe load holding.
