Airtac PB Pen-type Cylinder PB16X90SU
The AirTAC Airtac PB Pen-type Cylinder PB16X90SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 90mm 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 PB16X90SU
The AirTAC PB16X90SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to endure damp or mildly corrosive environments. The U suffix equips the back cover with a 90-degree perpendicular side air inlet, enabling flat plumbing in confined machinery.
This 16 mm bore unit features an M5x0.8 port and a 5 mm rod with an M10x1.0 rod-end thread. The integrated S magnet allows position detection using AirTAC reed or electronic switches. Travel is capped by a fixed TPU bumper at each end rather than an adjustable air cushion, and operating speed ranges from 50-800 mm/s at pressures up to 0.7 MPa.

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 PB16X90SU Is Used
PCB Depaneling Router
Actuates a tooling pin on an automated router fixture, using the 90.1 N pull at 0.5 MPa to secure small circuit boards during the cutting cycle.
Carton Flap Folder
Folds minor flaps on a compact packaging line where the U side inlet keeps plumbing flush against the machine frame to save space.
Lightweight Vertical Lift
Raises small electronic components weighing up to 5.1 kg in a pick-and-place jig, relying on the SUS304 rod for smooth coaxial thrust.
Is the Airtac PB Pen-type Cylinder PB16X90SU the Right Cylinder?
When sizing this 16 mm bore model, stepping down to the 12 mm bore yields a 56.5 N push at 0.5 MPa, while stepping up is not an option as this is the largest diameter in the PB family. For practical deployment, plan for a safe working load of about 60 N, which is roughly 60 percent of the 100.5 N theoretical push at 0.5 MPa. This equates to lifting approximately 5.1 kg vertically with a sane 2:1 safety margin.
To finalize your order, confirm the 16 mm bore, 90 mm stroke, M5x0.8 port, built-in S magnet, and U 90-degree side inlet. Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For fail-safe holding, an external stop or rod lock is required.
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 PB16X90SU 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 operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range 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. If moving high mass at speed, you should meter-out the exhaust or add an external shock absorber. The built-in S magnet allows tracking by AirTAC reed or electronic switches.
