Airtac PB Pen-type Cylinder PB16X75SULB
The AirTAC Airtac PB Pen-type Cylinder PB16X75SULB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 75mm 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 PB16X75SULB
The AirTAC PB16X75SULB is a JIS pen-size double-acting single-rod mini cylinder, delivering 100.5 N of push force at 0.5 MPa. Its slim SUS304 stainless body and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This configuration includes a built-in piston magnet for position sensing.
Equipped with a U 90-degree side inlet for flat plumbing and an LB mounting bracket, this unit installs cleanly in tight machine spaces. The Ø5 mm piston rod features an M10x1.0 thread, and air connects via an M5x0.8 port. It travels at 50-800 mm/s, relying on a fixed TPU bumper at each end to absorb impact. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa figure) to account for seal friction.
Airtac PB Pen-type Cylinder PB16X75SULB Technical Specifications
| Model | Airtac PB Pen-type Cylinder PB16X75SULB |
|---|---|
| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 75 mm |
| 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 300 mm |
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 PB16X75SULB Is Used
PCB Test Handler
Actuates spring probes on an in-line circuit test fixture, using the S magnet to confirm seat position for high-speed board validation.
Carton Flap Folder
Tucks minor flaps on a small carton erector, where the LB bracket provides a rigid pivot and the U inlet keeps pneumatic lines flush against the frame.
Textile Yarn Guide
Shifts a thread guide bar across a winding drum; the SUS304 barrel withstands humid dye-house conditions without corroding.
Is the Airtac PB Pen-type Cylinder PB16X75SULB the Right Cylinder?
This 16 mm bore generates 100.5 N push at 0.5 MPa. Stepping down, the 12 mm bore offers 56.5 N; stepping up is not available as this is the largest standard diameter in the PB family. With its 75 mm stroke, the thin Ø5 mm rod is built for coaxial thrust, so over extended reaches or off-axis loads you should add an external linear bearing to prevent side-loading damage.
Confirm your ordering essentials: 16 mm bore, 75 mm stroke, M5x0.8 port, built-in S magnet, U side inlet, and LB bracket. Note that a plain PB cylinder drifts when air is lost or the valve is centered, so applications requiring fail-safe holding need an external rod lock or mechanical stop.
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 PB16X75SULB FAQ
At 0.5 MPa it provides 100.5 N push and 90.7 N pull. 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 at speeds of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion, so meter-out the exhaust if moving heavy tooling. The built-in S magnet allows tracking by AirTAC reed or electronic switches.
