Airtac PB Pen-type Cylinder PB16X175SUFA
The AirTAC Airtac PB Pen-type Cylinder PB16X175SUFA is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 175mm 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 PB16X175SUFA
The AirTAC PB16X175SUFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 175mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. A built-in piston magnet (-S) allows integration with AirTAC reed or electronic switches for precise end-position detection. The U code specifies a 90-degree side air inlet, keeping plumbing flat against the machine frame, while the FA bracket provides a robust front mounting interface.
Constructed with a SUS304 stainless steel piston rod and barrel, this unit withstands damp and mildly corrosive environments. The slim round body saves valuable space and payload on end-of-arm tooling. Operating at speeds up to 800 mm/s, it relies on a fixed TPU bumper at each end to decelerate the piston. Because the bumper only absorbs energy in the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber. Air connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling.

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 PB16X175SUFA Is Used
PCB Depanelling Ejector
Pushes separated circuit boards out of a routing fixture on an SMT line, utilizing the 90-degree side inlet to maintain a low profile within the dense machinery.
Carton Flap Folder
Folds minor flaps on small pharmaceutical cartons before sealing, where the FA bracket fixes the slim body firmly to the conveyor side frame.
Lightweight Vertical Lift Gate
Raises and lowers a 4 kg sorting diverter on a packaging conveyor, safely within the 5.1 kg vertical lift capacity calculated at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB16X175SUFA the Right Cylinder?
Selecting the PB16X175SUFA gives you the maximum standard thrust in this mini family. If you need less force, the next size down is the 12mm bore, delivering 56.5 N push at 0.5 MPa. Since 16mm is the largest standard diameter in this series, stepping up requires transitioning to a completely different profile family. Plan for a safe working load of about 60 N (roughly 60 percent of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. This equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin.
When ordering, confirm the 16mm bore, 175mm stroke, M5x0.8 port, built-in magnet (S), 90-degree side inlet (U), and FA front mounting bracket. Note that a plain double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your application must hold a load without live pressure, install an external rod lock or mechanical stop. Additionally, the 5mm rod is designed for coaxial thrust; over the 175mm stroke, any off-axis load demands an external linear bearing guide.
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 PB16X175SUFA 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 force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
The -S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. For cushioning, it uses a fixed TPU bumper at each end that decelerates the piston over the final few millimeters; it is not an adjustable air cushion. For high-speed cycles with real tooling mass, you should meter-out the exhaust or add an external shock absorber.
