Airtac PB Pen-type Cylinder PB16X150CB
The AirTAC Airtac PB Pen-type Cylinder PB16X150CB 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 PB16X150CB
The AirTAC PB16X150CB is a double-acting JIS pen-size mini cylinder engineered for compact automation. It provides a robust 100.5 N push and 90.7 N pull at 0.5 MPa, scaling up to a maximum 140.7 N thrust at 0.7 MPa. The SUS304 stainless barrel and piston rod resist moisture in washdown or mildly corrosive settings, while the slim profile saves payload on light end-of-arm tooling.
This 16 mm bore unit features a 150 mm stroke and a CB double clevis back cover for pivoting loads. Air connects via an M5x0.8 port, driving the 5 mm rod at speeds of 50-800 mm/s. End-of-stroke energy is managed by fixed TPU bumpers rather than adjustable air cushions, meaning high-speed tooling mass may require an external shock absorber.

| 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 PB16X150CB Is Used
Diverter Gate Actuation
Swings a lightweight sorting flap on a packaging line using the CB double clevis to pivot the gate smoothly across the belt lane.
Product Ejection Pusher
Cycles at 50-800 mm/s to push small rejected items off a test fixture, relying on the 100.5 N thrust to clear parts reliably.
Pick-and-Place Arm Lift
Raises and lowers a delicate vacuum gripper on a PCB assembly machine, where the SUS304 body handles intermittent flux fumes.
Is the Airtac PB Pen-type Cylinder PB16X150CB the Right Cylinder?
When sizing this unit, stepping down to a 12 mm bore yields 56.5 N push at 0.5 MPa, while stepping up is not available as 16 mm is the largest in the PB family. For this 16 mm bore, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa rating) to account for seal friction. Vertically, it lifts about 5.1 kg with a 2:1 safety margin. To confirm your build, verify the 150 mm stroke, M5x0.8 port, CB double clevis, and the absence of a sensor magnet.
Because the 5 mm rod is designed for coaxial thrust, avoid side loading over the 150 mm extension. Note that a plain cylinder drifts when air is lost or the valve centers; the bumpers only decelerate near the end of travel and do not lock the load. For fail-safe holding, specify an external 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 PB16X150CB 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 back cover provides a double clevis joint ideal for pivoting mechanisms. End-of-stroke deceleration relies on fixed TPU bumpers rather than adjustable air cushions. If moving heavy tooling mass at high speeds, meter-out the exhaust or add an external shock absorber, as the bumpers only decelerate the last few millimeters.
