Airtac PB Pen-type Cylinder PB16X5SU
The AirTAC Airtac PB Pen-type Cylinder PB16X5SU 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 PB16X5SU
The AirTAC PB16X5SU is a JIS pen-size double-acting single-rod mini cylinder engineered for very short linear motion. 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 5 mm piston rod. The U suffix equips it with a 90-degree perpendicular side air inlet, allowing flat plumbing in confined spaces.
This unit features a built-in piston magnet for position detection with AirTAC reed or electronic switches. Because the stroke is only 5 mm, the fixed TPU bumper at each end effectively manages end-of-travel energy without requiring external shock absorbers. The M5x0.8 port and M10x1.0 rod-end thread provide straightforward integration into existing pneumatic setups.

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 PB16X5SU Is Used
Short-Stroke Clamping
Ideal for clamping small electronic components on a PCB assembly line where a 5 mm extension securely holds parts without consuming valuable vertical space.
Film Sealing Jaws
Provides rapid, repeatable actuation for lightweight sealing jaws in vertical form-fill-seal machinery, using the 90-degree side inlet to keep plumbing flush against the frame.
Ejector Pins
Suited for ejecting small molded plastic parts from tight tooling cavities, leveraging its 140.7 N maximum push force at 0.7 MPa to break parts free.
Is the Airtac PB Pen-type Cylinder PB16X5SU the Right Cylinder?
When sizing this 16 mm bore actuator, stepping down to the PB12X10S yields 56.5 N push at 0.5 MPa, while stepping up is not available as this is the largest bore in the PB family. For the PB16X5SU, plan for a safe working load of roughly 60 N, which is about 60% of its 100.5 N theoretical push at 0.5 MPa. This equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin. Ensure your order specifies the 5 mm stroke, M5x0.8 port, S magnet, and U side inlet.
Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. For a fail-safe hold, an external stop or rod lock is required. Additionally, the thin 5 mm rod is designed for coaxial thrust, so avoid side loads to prevent bending.
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 PB16X5SU FAQ
The PB16X5SU generates 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, a plain PB-type cylinder does not hold its load on air loss or when the valve is centered; the piston drifts and the fixed TPU bumper only decelerates near the stroke end. An external stop or rod lock is required for fail-safe load holding.
