Airtac PB Pen-type Cylinder PB16X95SU
The AirTAC Airtac PB Pen-type Cylinder PB16X95SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 95mm 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 PB16X95SU
The AirTAC PB16X95SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency automation. It generates 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 to fit tight end-of-arm tooling where space and payload are critical. The U option provides a 90-degree side air inlet for flat plumbing, keeping hose routing low-profile.
This 16 mm bore unit breathes through an M5x0.8 port and completes its 95 mm stroke at speeds of 50-800 mm/s. Because it carries the S designation, a built-in piston magnet allows position detection using AirTAC reed or electronic switches. Impact at stroke ends is managed by a fixed TPU bumper rather than an adjustable air cushion, meaning it decelerates only the final few millimeters of 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 PB16X95SU Is Used
PCB Depaneling Router
Provides the 100.5 N thrust at 0.5 MPa needed to plunge a small routing spindle into assembled circuit boards, while the 95 mm stroke handles varying panel thicknesses.
Carton Flap Folder
Extends rapidly at 50-800 mm/s to tuck secondary carton flaps on a continuous packaging line, using the U side inlet to keep pneumatic hoses flush against the machine frame.
Lightweight Parts Elevator
Lifts delicate plastic housings weighing up to 5.1 kg vertically through a 95 mm cycle, relying on the built-in S magnet to trigger an electronic switch at the raised position.
Is the Airtac PB Pen-type Cylinder PB16X95SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N—about 60% of the 100.5 N theoretical push at 0.5 MPa to account for seal friction and smooth travel. Alternatively, you can estimate a vertical lift capacity of about 5.1 kg with a sane 2:1 safety margin. If your application requires less force, the adjacent 12 mm bore provides 56.5 N push at 0.5 MPa; stepping up is not applicable as 16 mm is the largest in this series.
Confirm your ordering essentials: 16 mm bore, 95 mm stroke, M5x0.8 port, S magnet for sensing, and the U 90-degree side inlet. Note that a plain PB cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the end of the stroke. For fail-safe holding, an external rod lock or mechanical stop is required. Additionally, the 5 mm rod is built for coaxial thrust, so over the 95 mm stroke, use an external guide or linear bearing to prevent side-loading damage.
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 PB16X95SU FAQ
The 16 mm bore produces 100.5 N push and 90.7 N pull at 0.5 MPa, reaching maximums of 140.7 N push and 126.9 N pull at the 0.7 MPa family limit. It operates on filtered air at 0.15-0.7 MPa, runs at 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end that decelerates the piston only over the last few millimeters; it is not an adjustable air cushion, so high-speed tooling may require metering the exhaust or adding an external shock absorber. The S option includes a piston magnet for use with AirTAC reed or electronic switches.
