Airtac PB Pen-type Cylinder PB16X165SU
The AirTAC Airtac PB Pen-type Cylinder PB16X165SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 165mm 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 PB16X165SU
The AirTAC PB16X165SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 5 mm rod to endure mildly corrosive or damp production zones. The integrated U option provides a 90-degree side air inlet for flat plumbing, keeping the overall envelope minimal for tight robotic gripper assemblies.
Equipped with a built-in piston magnet (S code), this unit readily interfaces with AirTAC reed or electronic switches for precise end-of-stroke detection. Operating at speeds up to 800 mm/s, it relies on fixed TPU bumpers at both ends rather than adjustable air cushions. Because the 165 mm stroke is well within the 300 mm standard limit, it ships as a readily available configuration with an M5x0.8 port and an M10x1.0 rod-end thread.

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 PB16X165SU Is Used
PCB Depanelling Ejection
Deploys the 5 mm rod to push freshly routed circuit boards out of fixture nests, using the 90.1 N pull at 0.5 MPa to retract the thin probe rapidly for the next cycle.
Carton Flap Folding
Swings lightweight cardboard flaps on automated boxing lines where the U side inlet keeps hose routing flush against the machine frame without bending.
Sensor Array Positioning
Shifts a vision camera or laser profiling head between inspection stations, benefiting from the S magnet to trigger electronic switches at precise 165 mm intervals.
Is the Airtac PB Pen-type Cylinder PB16X165SU the Right Cylinder?
When sizing this 16 mm bore unit, plan for a safe working load of roughly 60 N (about 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. If you need to step down, the 12 mm bore offers 56.5 N push at 0.5 MPa; stepping up is not available as this is the largest diameter in the PB family. For vertical lifts, this actuator can safely manage about 5.1 kg against gravity using a 2:1 safety margin.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumpers only decelerate near the stroke ends rather than locking the rod. For fail-safe holding, specify an external rod lock. To finalize your order, confirm the 16 mm bore, 165 mm stroke, M5x0.8 port, S magnet, and U 90-degree side inlet.
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 PB16X165SU FAQ
At 0.5 MPa this 16 mm 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 fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters, which are not field-adjustable. If driving heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber. It does not hold position on air loss; install an external rod lock for fail-safe braking.
