Airtac PB Pen-type Cylinder PB16X8SU
The AirTAC Airtac PB Pen-type Cylinder PB16X8SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 8mm 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 PB16X8SU
The AirTAC PB16X8SU is a double-acting JIS pen-size mini cylinder engineered for short, rapid movements. It features a 16 mm bore and an 8 mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position sensing and a U-type back cover that introduces air via a 90-degree perpendicular inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. A fixed TPU bumper at each end absorbs impact during the final few millimeters of travel, operating at speeds from 50-800 mm/s.

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 PB16X8SU Is Used
Pick-and-Place Ejector
Mounts on a light end-of-arm tooling array to eject small stamped electronic contacts from a die in a single 8 mm rapid tap.
Carton Flap Tucker
Deploys a brief 8 mm stroke to tuck the inner flaps of small pharmaceutical cartons before the top sealer applies adhesive.
PCB Test Probe Actuator
Drives spring-loaded test pins down onto a printed circuit board nest, using the fixed TPU bumper to soften the final contact impact.
Is the Airtac PB Pen-type Cylinder PB16X8SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N, which is roughly 60% of the 100.5 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. If you need to lift a part vertically, this unit handles approximately 5.1 kg with a sane 2:1 safety margin. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push at 0.5 MPa. Since 16 mm is the largest standard bore in this family, there is no larger option available within the PB line. Remember that a plain cylinder drifts when air is lost or the valve is centered; an external rod lock is required for fail-safe holding. To order, confirm the 16 mm bore, 8 mm stroke, S magnet, U 90-degree side inlet, and your preferred mounting bracket.
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 PB16X8SU 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
The U back cover provides a 90-degree side air inlet for flat plumbing in tight spaces. The S code indicates a built-in piston magnet that allows you to attach AirTAC reed or electronic switches for position detection. The thin 5 mm rod is designed for coaxial thrust, so use an external guide if you have off-axis loads.
