Airtac PB Pen-type Cylinder PB16X30SU
The AirTAC Airtac PB Pen-type Cylinder PB16X30SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 30mm 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 PB16X30SU
The AirTAC PB16X30SU is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 30mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to endure damp or mildly corrosive environments. The integrated -S magnet enables position detection using AirTAC reed or electronic switches, while the U code specifies a 90-degree side air inlet for flat plumbing along your manifold.
This model uses an M5x0.8 port and an M10x1.0 rod-end thread to drive a 5mm rod. Because the U configuration side-loads the plumbing minimally, it fits well within tight end-of-arm tooling. The fixed TPU bumper at each end handles end-of-stroke deceleration, but it is not adjustable; for high cycling speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. 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.

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 PB16X30SU Is Used
PCB Test Handler
Drives the Z-axis probe head in an automated circuit tester, using the S magnet to confirm seat position and the slim body to fit dense testing arrays.
Carton Flap Folder
Tucks minor flaps on a compact packaging line, where the 90-degree U inlet keeps hoses flush against the machine frame to prevent snagging.
Textile Yarn Guide
Shifts a thread guide bar rapidly across a weaving loom, benefiting from the SUS304 stainless construction to resist humid manufacturing conditions.
Is the Airtac PB Pen-type Cylinder PB16X30SU the Right Cylinder?
Choosing this 16mm bore gives you the highest thrust in the PB family, stepping up from the 12mm option which provides 56.5 N push at 0.5 MPa. If your application requires less force, dropping down a size saves weight and payload, but for tasks needing this specific 100.5 N output at 0.5 MPa, the PB16X30SU is the correct fit. When sizing vertical lifts, expect to handle about 5.1 kg safely with a 2:1 margin.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumper only decelerates near the stroke end rather than locking the rod. If your process demands fail-safe position holding, incorporate an external stop or rod lock. To finalize your order, confirm the 16mm bore, 30mm stroke, M5x0.8 port, built-in magnet (S), 90-degree side inlet (U), and your required mounting bracket.
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 PB16X30SU 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 cylinder operates at 0.15-0.7 MPa with a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of its stroke and does not act as a brake. You must add an external rod lock or mechanical stop to hold a load safely.
