Airtac PB Pen-type Cylinder PB16X25SU
The AirTAC Airtac PB Pen-type Cylinder PB16X25SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 25mm 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 PB16X25SU
The AirTAC PB16X25SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, scaling up to a maximum 140.7 N push at 0.7 MPa. The SUS304 stainless barrel and slim profile drastically reduce payload on end-of-arm tooling, fitting easily into tight jig spaces. This specific configuration includes a built-in piston magnet (-S) for position sensing and a U-type back cover featuring a 90-degree side air inlet for flat, low-profile plumbing.
Air connections utilize an M5x0.8 port, while the Ø5 mm piston rod terminates in an M10x1.0 thread for secure load coupling. Travel is governed by a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only decelerates the final few millimeters, high-speed cycling with heavy tooling requires metering out the exhaust or adding an external shock absorber. The slender rod is built for pure coaxial thrust, so avoid side loading to prevent guide wear.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

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 PB16X25SU Is Used
PCB Depaneling Router
Provides the precise 100.5 N extend thrust at 0.5 MPa needed to clamp populated circuit boards during automated routing and V-groove separation.
Carton Flap Folder
Uses the 90-degree U inlet to keep plumbing flat against the machine frame while actuating small tucker blades to fold corrugated box flaps at high speed.
Lightweight Vertical Lift
Hoists delicate electronic components weighing up to 5.1 kg in a pick-and-place gantry, leveraging the SUS304 build for mildly corrosive washdown areas.
Is the Airtac PB Pen-type Cylinder PB16X25SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, which accounts for seal friction and smooth travel. For vertical lifts, this equates to hoisting about 5.1 kg with a sane 2:1 safety margin. If you need slightly less force, the adjacent Ø12 bore provides 56.5 N push at 0.5 MPa; stepping up is not required as Ø16 is the largest in this pen-size family. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, so fit an external rod lock if your application requires fail-safe load holding. Confirm your ordering essentials: 16 mm bore, 25 mm stroke, M5x0.8 port, S magnet, U side inlet, and any required LB, FA, or CJ 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 PB16X25SU FAQ
This double-acting cylinder generates 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, runs at speeds of 50-800 mm/s, and uses an M5x0.8 port with an M10x1.0 rod-end thread.
The S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for precise end-of-stroke detection. The U back cover provides a 90-degree side air inlet, allowing hoses to route parallel to the cylinder body to save vertical clearance in confined assemblies.
