Airtac PB Pen-type Cylinder PB16X250R
The AirTAC Airtac PB Pen-type Cylinder PB16X250R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 250mm 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 PB16X250R
The AirTAC PB16X250R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and piston rod, offering robust resistance in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, this 16 mm bore unit is driven through an M5x0.8 port and uses an R axial inlet for straightforward in-line plumbing.
Over its 250 mm stroke, the Ø5 mm rod provides coaxial thrust, though an external guide is recommended to prevent side-load deflection on long extensions. Deceleration relies on a fixed TPU bumper at each end, which absorbs impact over the final few millimeters rather than providing adjustable cushioning. For rapid cycling with heavy tooling, metering out the exhaust or adding an external shock absorber ensures smooth stops.

| Stroke | 250 mm |
| 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 PB16X250R Is Used
Package Flap Folding
Extends 250 mm to tuck cardboard flaps on a packaging line, utilizing the 100.5 N push force to cleanly crease heavy corrugated materials before sealing.
PCB Shuttle Ejection
Pushes populated circuit boards out of a test fixture, where the slim stainless body resists flux fumes and the R axial inlet keeps plumbing flush against the machine frame.
Lightweight Product Lifting
Raises small electronic enclosures between belt tiers, safely handling loads near the 5.1 kg vertical lift threshold without burdening the robotic arm with excessive mass.
Is the Airtac PB Pen-type Cylinder PB16X250R the Right Cylinder?
This 16 mm bore generates 100.5 N push at 0.5 MPa, sitting above the 12 mm option (56.5 N) for tasks needing more muscle, and representing the largest standard diameter in the PB family. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction, or expect to lift around 5.1 kg vertically with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 250 mm stroke, M5x0.8 porting, no sensor magnet, and the R axial back cover.
If air pressure drops or the valve is centered, this cylinder will not hold its position—the piston drifts, and the fixed bumper only decelerates it near the stroke end. Any application requiring fail-safe load holding must incorporate an external stop or a dedicated rod lock.
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 PB16X250R 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 cylinder operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
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. If cycling rapidly with real tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold its load if air is lost, so an external rod lock is required for fail-safe positioning.
