Airtac PB Pen-type Cylinder PB16X225SU
The AirTAC Airtac PB Pen-type Cylinder PB16X225SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 225mm 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 PB16X225SU
The AirTAC PB16X225SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight. Delivering 100.5 N of push force at 0.5 MPa, it integrates a built-in magnet for position sensing and a 90-degree side air inlet for flat plumbing.
This 16 mm bore model uses an M5x0.8 port and a 5 mm rod with an M10x1.0 rod-end thread. Traveling at speeds up to 800 mm/s, it relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters. Because the bumper is non-adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher velocities.

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 PB16X225SU Is Used
PCB Depaneling Router
Advances a cutting tool along a 225 mm path to singulate populated circuit boards, utilizing the slim stainless body to fit within dense routing fixtures.
Carton Flap Folder
Tucks minor flaps on small packaging lines at high speed, where the 90-degree side inlet keeps pneumatic plumbing flat against the machine frame.
Pallet Divert Gate
Actuates a lightweight routing gate to sort small product trays, taking advantage of the 100.5 N push force to overcome minor mechanical friction.
Is the Airtac PB Pen-type Cylinder PB16X225SU 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. If your vertical lift needs are higher, stepping up is not an option as this is the largest bore in the PB family, but stepping down to a 12 mm bore yields 56.5 N push at 0.5 MPa. For vertical lifts, this 16 mm model can handle about 5.1 kg safely with a 2:1 margin. Keep in mind a plain PB cylinder does not hold its position if air pressure drops or the valve centers; the piston will drift, so an external rod lock is required for fail-safe holding.
Confirm your ordering essentials: 16 mm bore, 225 mm stroke, M5x0.8 port, built-in magnet (S), 90-degree side inlet (U), and no mounting bracket. The 5 mm rod is designed purely for coaxial thrust; over this 225 mm stroke, avoid side loading by incorporating an external linear 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 PB16X225SU FAQ
The 16 mm bore provides 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 has a proof pressure of 1.2 MPa.
The U suffix provides a 90-degree perpendicular air inlet for flat plumbing in confined spaces. The S suffix indicates a built-in piston magnet, allowing you to mount AirTAC reed or electronic switches along the barrel for precise end-of-stroke position detection.
