Airtac PB Pen-type Cylinder PB16X175SU
The AirTAC Airtac PB Pen-type Cylinder PB16X175SU 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 PB16X175SU
The AirTAC PB16X175SU is a JIS pen-size double-acting single-rod mini cylinder featuring a 16mm bore and 175mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, making it the highest force class in this slim family. The SUS304 stainless barrel and piston rod resist moisture in washdown or mildly corrosive settings, while the compact round body saves valuable space on tight jigs and end-of-arm robotic tooling.
This specific configuration includes a built-in piston magnet (S) for position detection and a U-type back cover with a 90-degree perpendicular air inlet for flat plumbing along a machine frame. Air connects via an M5x0.8 port, and the load fastens to an M10x1.0 rod-end thread. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high speeds.

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 PB16X175SU Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line using the 100.5 N extend force, with the U side inlet keeping pneumatic hoses flush against the conveyor frame.
PCB Test Fixture
Drives a probe block onto printed circuit boards, relying on the S magnet to trigger an electronic switch and confirm the 175mm travel is complete before testing begins.
Small Parts Lift
Raises plastic trays weighing up to 5 kg vertically between processing stations, requiring an external guide to protect the thin Ø5 mm rod during the 175mm extension.
Is the Airtac PB Pen-type Cylinder PB16X175SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, which accounts for seal friction and smooth travel. If you need to lift a part vertically, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If your application requires less force, the adjacent PB12X100S provides 56.5 N push at 0.5 MPa; stepping up is not possible as 16mm is the largest bore in this series. A plain double-acting cylinder drifts when air is lost or the valve is centered, so fit an external rod lock if the payload must be held safely mid-stroke.
To order, confirm the 16mm bore, 175mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the U 90-degree side inlet back cover. The Ø5 mm piston rod is designed strictly for coaxial thrust, so over this 175mm stroke add an external linear bearing to prevent side-load binding.
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 PB16X175SU FAQ
At 0.5 MPa this 16mm bore cylinder 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 to decelerate the piston over the last few millimeters, which is not field-adjustable. The built-in S magnet allows you to mount AirTAC reed or electronic switches along the body for precise end-of-stroke detection.
