Airtac PB Pen-type Cylinder PB16X150SULB
The AirTAC Airtac PB Pen-type Cylinder PB16X150SULB 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 PB16X150SULB
The AirTAC PB16X150SULB is a JIS pen-size double-acting mini cylinder engineered for compact automation. It delivers 100.5 N of push and 90.7 N of pull at 0.5 MPa, operating through a 150 mm stroke. The SUS304 stainless round barrel and piston rod resist moisture in washdown or mildly corrosive settings, keeping the assembly slim for tight end-of-arm tooling.
This configuration includes a built-in piston magnet (-S) for position sensing, a 90-degree side air inlet (U), and an LB mounting bracket. Air connects via an M5x0.8 port, driving the Ø5 mm rod with an M10x1.0 end thread. Fixed TPU bumpers absorb impact at stroke ends, and the unit runs at speeds from 50-800 mm/s.

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 PB16X150SULB Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the LB bracket to secure the slim body while the U inlet keeps pneumatic lines flush against the machine frame.
PCB Test Fixture
Drives a probe block down onto printed circuit boards, relying on the built-in S magnet to trigger an electronic switch and confirm the 150 mm travel endpoint.
Lab Sample Dispenser
Pushes a syringe or valve plunger in a wet analytical instrument, where the SUS304 stainless barrel withstands ambient moisture and chemical vapors.
Is the Airtac PB Pen-type Cylinder PB16X150SULB the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction at 0.5 MPa. For vertical lifts, expect to raise about 5.1 kg safely with a 2:1 margin. If you need less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; if your jig requires more thrust, this Ø16 is the largest in the family at 100.5 N push. Because the thin Ø5 mm rod handles coaxial thrust best, add an external linear bearing for side loads over this 150 mm stroke.
This specific model is ordered with the S magnet for reed or electronic switches, the U cover for flat plumbing, and the LB bracket for foot mounting. Note that a standard PB cylinder drifts if air pressure drops or the valve is centered, so an external rod lock is required to hold a load safely without live pressure.
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 PB16X150SULB 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 cylinder operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses fixed TPU bumpers at both ends to decelerate the piston over the final few millimeters, which are not adjustable or field-tunable. If you are moving real tooling mass at high speed, meter-out the exhaust or add an external shock absorber. The cylinder will not hold a load if air is lost; it drifts, so an external stop is needed for fail-safe positioning.
