Airtac PB Pen-type Cylinder PB16X160CB
The AirTAC Airtac PB Pen-type Cylinder PB16X160CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 160mm 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 PB16X160CB
The AirTAC PB16X160CB is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency automation. It features a 16mm bore and 160mm stroke, delivering 100.5 N of push force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. Air connections utilize an M5x0.8 port, and the rod end features an M10x1.0 thread for secure load coupling.
This specific configuration includes a CB double clevis back cover, allowing the cylinder to pivot smoothly on a pin to accommodate lateral misalignment during operation. Instead of an adjustable air cushion, the body relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters of travel. Because the rod is a slender 5 mm diameter, maintaining coaxial alignment is critical over the 160mm stroke to prevent binding and premature seal wear.

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 PB16X160CB Is Used
Package Diverting Gate
Actuates a lightweight pivoting flap on a packaging conveyor to sort small cartons, utilizing the CB clevis to swing the gate smoothly into the flow.
PCB Test Fixture
Drives a delicate probe head down onto printed circuit boards, where the slim stainless body fits within dense test jigs and provides consistent 100.5 N clamping at 0.5 MPa.
Label Applicator Arm
Pushes a label tamping head onto moving product boxes, relying on the fast 50-800 mm/s travel speed and bumpers to absorb rapid end-of-stroke impacts.
Is the Airtac PB Pen-type Cylinder PB16X160CB the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction by applying a 60% margin to the 100.5 N theoretical push at 0.5 MPa. In vertical lift scenarios, this translates to lifting about 5.1 kg safely with a 2:1 gravity margin. If you need less force, stepping down to the 12mm bore provides 56.5 N push at 0.5 MPa; if you require more power, this 16mm bore is the largest available in the series, offering a maximum push of 140.7 N at 0.7 MPa. Be aware that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is necessary for fail-safe load holding.
To order correctly, confirm the 16mm bore, 160mm stroke, M5x0.8 porting, and the CB double clevis option. This unit does not include a sensor magnet; if position feedback is required, select an -S suffix variant. For high-speed cycling with heavy tooling, the fixed TPU bumpers may bottom out, so consider metering out the exhaust or adding external shock absorbers.
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 PB16X160CB FAQ
This 16mm bore double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa, supports speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a standard double-acting pen cylinder will drift downward if air is lost or the directional valve is centered. The fixed TPU bumpers only decelerate the piston near the end of the stroke and do not act as a locking brake. An external rod lock or mechanical stop is required for fail-safe load holding.
