Airtac PB Pen-type Cylinder PB16X290SU
The AirTAC Airtac PB Pen-type Cylinder PB16X290SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 290mm 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 PB16X290SU
The AirTAC PB16X290SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to resist damp or mildly corrosive industrial environments. The U suffix equips the back cover with a 90-degree perpendicular air inlet, allowing flat plumbing in confined spaces.
Air enters via an M5x0.8 port to drive the 5 mm rod, which features an M10x1.0 rod-end thread for secure load coupling. Because the unit carries the S designation, it contains a built-in piston magnet ready for AirTAC reed or electronic switches. Deceleration at stroke ends relies on a fixed TPU bumper rather than an adjustable air cushion, meaning external shock absorbers may be required for heavy tooling masses moving at high speeds.

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 PB16X290SU Is Used
PCB Depaneling Router
Actuates a cutting head across a 290 mm span to singulate printed circuit boards, benefiting from the 100.5 N push force and compact stainless body.
Carton Flap Folder
Extends to tuck corrugated flaps prior to sealing, using the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame.
Sorting Diverter Arm
Pushes lightweight parcels down a secondary chute, relying on the built-in S magnet to trigger an electronic switch for position confirmation.
Is the Airtac PB Pen-type Cylinder PB16X290SU the Right Cylinder?
This 16 mm bore provides the highest thrust in the PB family, pushing 100.5 N at 0.5 MPa. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push, making the PB16 the definitive choice when maximum mini-cylinder power is needed. For practical sizing, plan for a safe working load of roughly 60 N, which accounts for seal friction at standard 0.5 MPa operation.
When ordering, verify the 290 mm stroke against your jig constraints, along with the M5x0.8 porting and the U-type 90-degree side inlet. Note that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is necessary for fail-safe load holding. Furthermore, over this extended 290 mm travel, the slender 5 mm rod requires an external linear bearing to prevent side-load 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 PB16X290SU 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 of 50-800 mm/s.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; this is not an adjustable air cushion or a locking brake. For position feedback, the built-in S magnet is compatible with AirTAC reed or electronic switches.
