Airtac PB Pen-type Cylinder PB16X150SR
The AirTAC Airtac PB Pen-type Cylinder PB16X150SR 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 PB16X150SR
The AirTAC PB16X150SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 150mm stroke, generating 100.5 N of push and 90.7 N of pull at 0.5 MPa. The slim SUS304 stainless steel round barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This specific configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet for position sensing.
Air enters via the M5x0.8 port, driving the Ø5 mm rod at speeds of 50-800 mm/s. Because the unit relies on a fixed TPU bumper at each end rather than an adjustable air cushion, it decelerates only over the last few millimeters of travel. For payloads moving at higher velocities, adding an external shock absorber or metering out the exhaust is recommended. The -S magnet supports AirTAC reed or electronic switches to track stroke endpoints accurately.

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 PB16X150SR Is Used
PCB Depaneling Router
Actuates a cutting tool guide on an electronics assembly line, utilizing the 100.5 N push force to maintain precise positioning while the SUS304 body withstands machining coolant.
Package Sorting Diverter
Pushes small parcels laterally on a logistics conveyor, where the compact pen-size profile fits within tight side-rail gaps and the R axial inlet keeps plumbing flush against the frame.
Lab Sample Ejection
Ejects processed vials from a centrifuge carousel, using the built-in S magnet to trigger an electronic switch that confirms the 150mm full extension before the rotor resumes.
Is the Airtac PB Pen-type Cylinder PB16X150SR the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N, which is roughly 60% of the 100.5 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. In vertical lift scenarios, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If you need less force, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa; if you require more power, the 16mm is the largest available in this family, so a larger profile body would be necessary. Keep in mind the thin Ø5 mm rod is designed for coaxial thrust, so over this 150mm stroke an external linear bearing should be added if side loads are present.
A standard PB-type cylinder does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper only decelerates near the end of the stroke. For fail-safe load holding, an external rod lock or mechanical stop is required. Confirm your ordering essentials: 16mm bore, 150mm stroke, M5x0.8 porting, S magnet, R axial inlet, and your desired mounting bracket.
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 PB16X150SR FAQ
This double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa, with a maximum output of 140.7 N push and 126.9 N pull at 0.7 MPa. Operating pressure ranges from 0.15-0.7 MPa, and the maximum operating speed is 800 mm/s.
No, a plain PB cylinder drifts if air is lost and cannot hold a load without an external rod lock. Additionally, the fixed TPU bumper only decelerates the piston over the last few millimeters; for heavy tooling moving at high speed, you must meter-out the exhaust or add an external shock absorber.
