Airtac PB Pen-type Cylinder PB16X65SU
The AirTAC Airtac PB Pen-type Cylinder PB16X65SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 65mm 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 PB16X65SU
The AirTAC PB16X65SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 16mm bore and generates 100.5 N of push force at 0.5 MPa, extending to a maximum of 140.7 N at 0.7 MPa. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp production zones, while the U code specifies a 90-degree side air inlet for flat plumbing against machine frames.
This variant includes the S code for a built-in piston magnet, enabling position detection with AirTAC reed or electronic switches. Air connects via an M5x0.8 port, and the Ø5 mm rod utilizes an M10x1.0 end thread for secure load coupling. Operating speeds reach 50-800 mm/s, with fixed TPU bumpers at both ends to absorb impact during transition.

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 PB16X65SU Is Used
PCB Depaneling Router
Pushes a localized support pin against a circuit board during routing operations, utilizing the 90-degree side inlet to keep pneumatic lines flush with the tight machinery frame.
Blister Pack Sealing Jig
Cycles rapidly to clamp thin film materials under a heated platen, where the SUS304 barrel withstands occasional condensation from steam-based packaging environments.
Sorting Diverter Arm
Actuates a lightweight paddle to deflect small plastic components on a packaging line, relying on the built-in S magnet to trigger an electronic switch for stroke confirmation.
Is the Airtac PB Pen-type Cylinder PB16X65SU the Right Cylinder?
When sizing this actuator, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa, whereas this 16mm unit provides 100.5 N at the same pressure. For practical sizing, plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction. In vertical lift scenarios, this equates to lifting about 5.1 kg with a sane 2:1 safety margin.
Confirm your ordering essentials: 16mm bore, 65mm stroke, M5x0.8 port, S magnet, and U 90-degree side inlet. Because the fixed TPU bumper only decelerates the last few millimeters, meter-out the exhaust or add an external shock absorber when moving heavy tooling at high speeds. Note that a plain PB cylinder does not hold its position on air loss; the piston will drift, so an external rod lock is required for fail-safe holding.
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 PB16X65SU FAQ
This double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 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 cylinder will drift if air is lost or the valve is centered, as the fixed TPU bumper only decelerates near stroke end and does not act as a brake. You must install an external rod lock or mechanical stop to safely hold a suspended load.
