Airtac PB Pen-type Cylinder PB16X150SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X150SCB 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 PB16X150SCB
The AirTAC PB16X150SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency automation. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and piston rod to resist damp or mildly corrosive environments while saving critical space on end-of-arm tooling. The integrated -S magnet enables position detection using AirTAC reed or electronic switches.
This specific configuration includes a CB double clevis back cover, allowing the cylinder to pivot smoothly on articulated loads. Air flows through M5x0.8 ports, driving the 5 mm rod at speeds of 50-800 mm/s. Deceleration is handled by a fixed TPU bumper at each end; because it is not adjustable, high-speed cycles with heavy tooling require metering the exhaust or adding an external shock absorber.

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 PB16X150SCB Is Used
Pivot-Actuated Pick & Place
Ideal for swinging small electronic components between conveyor belts, leveraging the CB double clevis to articulate the arm without binding.
Carton Flap Folding
Drives a hinged arm to tuck packaging flaps on a high-speed filling line, where the SUS304 body withstands washdown environments.
Vertical Part Ejection
Pushes lightweight molded plastic parts out of a die, lifting up to 5.1 kg safely with a 2:1 margin at 0.5 MPa before retracting.
Is the Airtac PB Pen-type Cylinder PB16X150SCB the Right Cylinder?
Selecting the PB16X150SCB gives you the maximum standard thrust in this mini family, stepping up from the 12 mm bore (56.5 N push at 0.5 MPa) which offers a lighter footprint for lighter duties. If your application requires even more force, you would need to step outside the pen-size format entirely. For this 16 mm bore, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
When ordering, confirm the 16 mm bore, 150 mm stroke, M5x0.8 port, S magnet, and CB double clevis. Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift. For fail-safe vertical holding, an external rod lock or mechanical stop is required. Additionally, the 5 mm rod is built for coaxial thrust; over the 150 mm stroke, avoid side loading by guiding the payload externally.
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 PB16X150SCB 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
The CB suffix denotes a double clevis back cover, allowing the cylinder body to pivot during the stroke to accommodate angular load movement. End-of-stroke deceleration relies on a fixed TPU bumper at each end, which is not adjustable. For high-mass or high-speed applications, you should meter-out the exhaust or install an external shock absorber to prevent bottoming out.
