Airtac PB Pen-type Cylinder PB16X75SU
The AirTAC Airtac PB Pen-type Cylinder PB16X75SU 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 PB16X75SU
The AirTAC PB16X75SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It yields 100.5 N of push and 90.7 N of pull at 0.5 MPa, scaling to a maximum 140.7 N push at 0.7 MPa. The SUS304 stainless barrel and rod provide reliable durability in damp or mildly corrosive environments, while the slim profile 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 using AirTAC reed or electronic switches. The U designation indicates a 90-degree perpendicular side air inlet, allowing flat plumbing in restricted areas. Air connects via an M5x0.8 port, and the Ø5 mm piston rod features an M10x1.0 rod-end thread. A fixed TPU bumper at each end manages end-of-stroke deceleration.

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 PB16X75SU Is Used
PCB Depaneling Router
Provides the precise 100.5 N thrust at 0.5 MPa to actuate the cutting blade assembly on an automated PCB depaneling machine, with the U side inlet keeping the hose routing flat against the gantry.
Blister Pack Sealing
Drives the small heated platen on a medical blister packaging line, using the built-in S magnet to trigger electronic switches for precise dwell time at the 75 mm stroke end.
Sorter Diverter Arm
Powers a lightweight pneumatic diverter arm on a parcel conveyor, relying on the SUS304 stainless build to withstand humid warehouse conditions without binding.
Is the Airtac PB Pen-type Cylinder PB16X75SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N (about 60% of the 100.5 N @0.5 MPa figure) 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. If you need less force, stepping down to the Ø12 bore provides 56.5 N push at 0.5 MPa; if you require more power, note that Ø16 is the largest available in this pen-size family. To confirm your ordering essentials: 16 mm bore, 75 mm stroke, M5x0.8 port, S magnet, U 90-degree side inlet, and no mounting bracket. A plain PB cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe positioning.
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 PB16X75SU FAQ
This 16 mm bore double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa, reaching a maximum 140.7 N push and 126.9 N pull at 0.7 MPa. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa. It operates at speeds between 50-800 mm/s across a temperature range of -20 to +70 C.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; this is not an adjustable air cushion or a locking brake. At high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, if air is lost, the bumper will not hold the load—the piston drifts, so an external stop is needed for fail-safe holding.
