Airtac PB Pen-type Cylinder PB16X175CB
The AirTAC Airtac PB Pen-type Cylinder PB16X175CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 175mm 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 PB16X175CB
The AirTAC PB16X175CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your jig. Delivering 100.5 N of push force at 0.5 MPa, it provides robust thrust for its footprint.
This 16 mm bore unit incorporates a CB double clevis back cover, allowing the body to pivot smoothly on a pin to accommodate articulating loads. Air connects via an M5x0.8 port, and the rod end utilizes an M10x1.0 thread for secure load coupling. Because it lacks a sensor magnet, position detection is not supported on this specific configuration.

| 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 PB16X175CB Is Used
Package Diverter Flap
Pivots a lightweight routing gate on a packaging conveyor to sort small cartons, utilizing the CB clevis to accommodate the swing arc during actuation.
Textile Loom Tensioner
Adjusts yarn tensioning guides in a humid textile manufacturing environment, where the SUS304 stainless barrel resists moisture corrosion over continuous cycles.
Pneumatic Lift Gate
Raises and lowers a small access hatch on an automated test fixture, lifting approximately 5.1 kg vertically with a safe 2:1 margin at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB16X175CB the Right Cylinder?
When sizing this actuator, consider stepping down to the PB12 bore (56.5 N push at 0.5 MPa) for lighter gripping tasks, or recognize that the PB16 is the largest available in this pen-size family, offering the maximum 100.5 N push at 0.5 MPa. For this 175 mm stroke, the slim Ø5 mm rod is built strictly for coaxial thrust; adding an external linear guide is highly recommended to prevent side-load binding on longer extensions. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
To finalize your order, confirm the essentials: 16 mm bore, 175 mm stroke, M5x0.8 air port, no sensor magnet, and the CB double clevis mount. Note that a plain PB cylinder will drift and lose its position if air pressure drops or the valve is centered—the fixed bumper only decelerates the piston near the stroke end, so an external rod lock is required for fail-safe holding.
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 PB16X175CB FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, with maximums of 140.7 N push and 126.9 N pull at the 0.7 MPa pressure limit. It operates at speeds of 50-800 mm/s and uses an M5x0.8 port.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so you should meter-out the exhaust or add an external shock absorber for heavy high-speed loads. It does not hold position on air loss—the piston will drift, requiring an external rod lock for fail-safe vertical holding.
