Airtac PB Pen-type Cylinder PB16X150SU
The AirTAC Airtac PB Pen-type Cylinder PB16X150SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 150mm 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 PB16X150SU
The AirTAC PB16X150SU 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, scaling up to a maximum 140.7 N push at 0.7 MPa. The SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while the slim round profile saves valuable space on tight jigs and light end-of-arm tooling.
This specific configuration includes a built-in piston magnet (-S) for position sensing and a U-type back cover featuring a 90-degree side air inlet for flat plumbing. Air connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread. Travel is managed by a fixed TPU bumper at each end that decelerates the piston over the final few millimeters; because it is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving heavy tooling 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 PB16X150SU Is Used
PCB Depaneling Router
Provides the 100.5 N extension force needed to plunge a router bit or actuate a cutting gate on an electronics assembly line, with the U side inlet keeping pneumatic tubing flush against the machine frame.
Carton Flap Folder
Drives a lightweight mechanical arm to tuck minor flaps on a packaging conveyor, utilizing the fixed TPU bumpers to absorb the impact of repeated high-frequency strokes at up to 800 mm/s.
Small Parts Lift Gate
Elevates lightweight 5 kg component trays between conveyor tiers; the SUS304 construction resists humidity in washdown areas, though an external guide is required to maintain rod coaxiality over the 150 mm extension.
Is the Airtac PB Pen-type Cylinder PB16X150SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N (about 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift applications, this equates to lifting about 5.1 kg safely with a 2:1 margin. If you need less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; since Ø16 is the largest in this family, stepping up requires transitioning to a larger profile series. To finalize your order, confirm the 16 mm bore, 150 mm stroke, M5x0.8 port, S magnet, U side inlet, and required mounting brackets.
Keep in mind that a standard double-acting cylinder like this does not hold its position if air pressure drops or the valve is centered—the piston will drift. If your application requires fail-safe load holding, you must integrate an external stop or rod lock. Additionally, the Ø5 mm rod is designed for coaxial thrust; over the 150 mm stroke, any off-axis load warrants an external linear guide to prevent binding.
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 PB16X150SU FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, reaching a maximum of 140.7 N push and 126.9 N pull at the 0.7 MPa operating pressure limit. It operates at speeds between 50 and 800 mm/s.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends and do not act as a brake. An external rod lock or mechanical stop is required for fail-safe load holding.
