Airtac PB Pen-type Cylinder PB16X300SU
The AirTAC Airtac PB Pen-type Cylinder PB16X300SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 300mm 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 PB16X300SU
The AirTAC PB16X300SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, peaking at 140.7 N extend force under the 0.7 MPa maximum operating pressure. The slim SUS304 stainless barrel and piston rod provide dependable corrosion resistance for damp production areas, while the U suffix designates a 90-degree side air inlet for flat, space-saving plumbing.
This 16 mm bore unit travels a full 300 mm stroke, supported by a Ø5 mm rod with an M10x1.0 rod-end thread. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, the end-of-stroke deceleration is limited to the final few millimeters. For high-speed tooling mass, metering out the exhaust or adding an external shock absorber is recommended to prevent hard bottoming.

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 PB16X300SU Is Used
Package Diverting Arm
Extends a 300 mm lightweight flap on a packaging line to reroute small cartons, using the U side inlet to keep plumbing flush against the conveyor frame.
PCB Edge Pin Pusher
Cycles a stainless pin to register delicate circuit boards into a testing fixture, relying on the SUS304 body to resist flux and washdown moisture.
Tote Stacking Ejector
Pushes empty plastic totes out of a vertical magazine, where the 140.7 N max extend force easily overcomes tote friction without needing a larger profile body.
Is the Airtac PB Pen-type Cylinder PB16X300SU the Right Cylinder?
Selecting this model means stepping up to the largest bore in the PB family; the next size down is the Ø12 bore, which provides 56.5 N push at 0.5 MPa. At 300 mm, this cylinder utilizes the maximum standard stroke for the Ø16 range. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N @0.5 MPa figure), which translates to lifting approximately 5.1 kg vertically with a sane 2:1 margin.
When ordering, confirm the 16 mm bore, 300 mm stroke, M5x0.8 port, built-in S magnet for position sensing, and the U 90-degree side inlet. Note that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. If your application requires fail-safe load holding, you must incorporate an external stop or rod lock. Additionally, the Ø5 mm rod is designed for coaxial thrust; over this long 300 mm extension, adding an external linear bearing prevents side-load binding.
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 PB16X300SU FAQ
This 16 mm bore double-acting cylinder generates 100.5 N push and 90.7 N pull at 0.5 MPa, with maximum forces of 140.7 N push and 126.9 N pull at the 0.7 MPa operating limit. It travels at 50-800 mm/s, uses an M5x0.8 port, and features a 300 mm stroke.
The S suffix means it has a built-in piston magnet compatible with AirTAC reed or electronic switches. Cushioning is handled by fixed TPU bumpers at both ends, which are not adjustable; for heavy loads at high speeds, you should add an external shock absorber or meter-out the exhaust.
