Airtac PB Pen-type Cylinder PB16X210SU
The AirTAC Airtac PB Pen-type Cylinder PB16X210SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 210mm 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 PB16X210SU
The AirTAC PB16X210SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a Ø5 mm piston rod to endure damp or mildly corrosive environments. The integrated -S magnet enables position feedback using AirTAC reed or electronic switches.
This specific configuration includes a U-type back cover featuring a 90-degree perpendicular air inlet for flat plumbing in confined spaces. Operating at speeds up to 800 mm/s, the unit relies on a fixed TPU bumper at each end to decelerate the stroke. Because the 210 mm stroke is quite long for a Ø5 mm rod, maintaining coaxial thrust is critical to prevent deflection.

| Rod diameter | Ø5 mm |
| Stroke | 210 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |

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 PB16X210SU Is Used
Package Diverting
Pushes small cartons on a packaging line using the 90-degree side inlet to keep plumbing flush against the conveyor frame.
PCB Test Fixture
Drives a probe block over 210 mm to contact circuit boards, relying on the integrated magnet for electronic switch positioning.
Lab Sample Transfer
Moves fluid vials within a humid analytical machine, benefiting from the SUS304 stainless construction against moisture.
Is the Airtac PB Pen-type Cylinder PB16X210SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa push force) to account for seal friction and smooth travel. For vertical lifting, this translates to safely hoisting approximately 5.1 kg with a 2:1 safety margin. If your application requires less force, the neighbouring Ø12 bore provides 56.5 N push at 0.5 MPa; stepping up is not applicable as Ø16 is the largest in this series.
Confirm your ordering essentials: this model features a 16 mm bore, 210 mm stroke, M5x0.8 air port, M10x1.0 rod-end thread, an integrated sensor magnet, and a U-type 90-degree side inlet. Note that a plain PB cylinder drifts if air pressure is lost or the valve is centered, so an external rod lock is required for fail-safe load holding.
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 PB16X210SU 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.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters. It is not adjustable, so at high speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber.
