Airtac PB Pen-type Cylinder PB16X280SU
The AirTAC Airtac PB Pen-type Cylinder PB16X280SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 280mm 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 PB16X280SU
The AirTAC PB16X280SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers 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 environments. Plumbing is simplified by the U type 90-degree side air inlet, keeping the footprint flat against your machine frame.
This 16 mm bore unit travels a 280 mm stroke and features a built-in magnetic piston (-S) for position feedback via AirTAC reed or electronic switches. End-of-stroke deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the 280 mm stroke is lengthy relative to the Ø5 mm rod, maintaining coaxial thrust is critical; an external linear bearing should be added if any off-axis load is present.

| 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 PB16X280SU Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the 90.1 N pull force to swing parcels into secondary sorting lanes.
PCB Test Fixture
Drives a probe head down onto printed circuit boards, relying on the S magnet to trigger an electronic switch and confirm test contact.
Lab Sample Dispenser
Extends 280 mm to lower a fluid nozzle into corrosive reagent trays, benefiting from the SUS304 stainless construction in damp environments.
Is the Airtac PB Pen-type Cylinder PB16X280SU the Right Cylinder?
When sizing this 16 mm bore class, stepping down to a 12 mm bore drops the 0.5 MPa push force to 56.5 N, while stepping up is not an option as this is the largest diameter in the PB family. A practical safe working load for this model is about 60 N (roughly 60% of the 0.5 MPa theoretical force), which equates to lifting around 5.1 kg vertically with a sane 2:1 safety margin. Keep in mind a plain PB cylinder drifts when air is lost or the valve is centered, so an external rod lock is required for fail-safe load holding.
To order, confirm the 16 mm bore, 280 mm stroke, M5x0.8 port, S magnet for sensing, and the U 90-degree side inlet back cover. The fixed TPU bumpers only decelerate the final few millimeters of travel; at high speeds with heavy tooling mass, meter-out the exhaust or install an external shock absorber to prevent bottoming out.
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 PB16X280SU 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 is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, a standard PB cylinder does not lock its position on air loss or valve centering; the piston will drift. The fixed TPU bumpers only decelerate the rod near the end of stroke and act as a brake. For fail-safe holding, you must add an external stop or rod lock.
