Airtac PB Pen-type Cylinder PB16X15SU
The AirTAC Airtac PB Pen-type Cylinder PB16X15SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 15mm 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 PB16X15SU
The AirTAC PB16X15SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight. Delivering 100.5 N of push force at 0.5 MPa, this 16 mm bore unit is paired with a short 15 mm stroke for rapid, tight-range actuation.
Air connects via the U-type 90-degree perpendicular side inlet, allowing flat plumbing against machine frames. The integrated S-code piston magnet enables position detection using AirTAC reed or electronic switches. End-of-stroke deceleration relies on fixed TPU bumpers rather than adjustable air cushions, and the M5x0.8 port ensures efficient airflow for its 50-800 mm/s speed range.

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 PB16X15SU Is Used
PCB Depaneling Router
Provides the precise 15 mm clamping thrust to hold circuit boards steady during high-speed routing operations.
Blister Pack Sealing
Cycles rapidly to press and seal transparent plastic blisters against cardboard backing in continuous packaging lines.
Lab Dispense Valve
Actuates a small pneumatic dispensing nozzle for micro-volume adhesive applications requiring repeatable short strokes.
Is the Airtac PB Pen-type Cylinder PB16X15SU the Right Cylinder?
When sizing this actuator, note that the PB16X15SU provides 100.5 N push and 90.7 N pull at 0.5 MPa. If you need less force, the adjacent PB12X10S delivers 56.5 N push, stepping down the power class. This 16 mm model represents the largest bore in the PB family, so there is no larger standard option to step up to. 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. For vertical lifts, expect to raise about 5.1 kg safely with a 2:1 margin.
Remember that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For fail-safe holding, specify an external rod lock or mechanical stop. Confirm your ordering essentials: 16 mm bore, 15 mm stroke, M5x0.8 port, S magnet, and U side inlet.
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 PB16X15SU 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. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa, and it operates at speeds between 50-800 mm/s.
The U code indicates a 90-degree perpendicular side air inlet, which allows for flat plumbing in tight spaces. Instead of an adjustable air cushion, the cylinder uses fixed TPU bumpers at both ends to absorb impact during the final few millimeters of travel. For high-speed loads with significant mass, you should meter-out the exhaust or add an external shock absorber.
