Airtac PB Pen-type Cylinder PB16X150R
The AirTAC Airtac PB Pen-type Cylinder PB16X150R 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 PB16X150R
The AirTAC PB16X150R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless round barrel and screwed-in covers keep weight down for light end-of-arm tooling, while resisting damp or mildly corrosive industrial environments.
This 16 mm bore unit features a 150 mm stroke and an R axial air inlet for in-line plumbing. It relies on a fixed TPU bumper at each end to decelerate the piston across its 50-800 mm/s speed range. Because the rod is a slender Ø5 mm threaded M10x1.0, it is built for coaxial thrust rather than side loading, making an external guide advisable over this longer stroke.
When sizing, plan for a safe working load of roughly 60 N, which is about 60% of the 0.5 MPa push rating, to account for seal friction and smooth travel. For vertical lifts, this equates to raising approximately 5.1 kg safely with a 2:1 margin. Note that a plain PB body does not hold position if air pressure drops; the piston will drift, so an external rod lock is required for fail-safe holding. To confirm exact mounting bracket availability, check the datasheet.

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 PB16X150R Is Used
PCB Depaneling Router
Pushes a carrier fixture against a hard stop on an electronic assembly line, using the 100.5 N extend force to secure small panels during routing without occupying valuable floor space.
Carton Flap Folder
Tucks minor flaps on a compact packaging conveyor, where the slim stainless barrel resists humid washdown environments and the 150 mm stroke clears varying box widths.
Light Parts Elevator
Lifts delicate plastic components weighing up to 5.1 kg vertically between belt tiers, relying on the M10x1.0 rod thread for secure load coupling and an external guide to prevent rod binding.
Is the Airtac PB Pen-type Cylinder PB16X150R the Right Cylinder?
This 16 mm bore sits at the top of the PB family range. If you need less force, stepping down to the 12 mm bore yields a 56.5 N push at 0.5 MPa, while the 16 mm provides the maximum 100.5 N push available in this series. When ordering, verify the 150 mm stroke, the M5x0.8 port, the R axial back cover inlet, and confirm whether you need an LB, FA, or CJ bracket.
Because the fixed TPU bumper only absorbs impact over the final few millimeters, high-speed cycles with heavy tooling may bottom it out. Metering out the exhaust or adding an external shock absorber extends service life. Remember that without live air pressure, the cylinder cannot hold a load and will drift.
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 PB16X150R 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 the speed range is 50-800 mm/s.
The R suffix indicates an axial air inlet for straight in-line plumbing. It uses a fixed TPU bumper at each end rather than an adjustable air cushion, meaning it only decelerates the last few millimeters of travel. For high-speed or heavy loads, you should meter-out the exhaust or add an external shock absorber.
