Airtac PB Pen-type Cylinder PB16X160SR
The AirTAC Airtac PB Pen-type Cylinder PB16X160SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 160mm 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 PB16X160SR
The AirTAC PB16X160SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It produces 100.5 N of push and 90.7 N of pull at 0.5 MPa, driven by a 16 mm bore and 160 mm stroke. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp production lines while saving critical space and payload on light end-of-arm tooling.
This configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet (S) for position sensing. Air connects via an M5x0.8 port, and the Ø5 mm rod features an M10x1.0 end thread. Deceleration relies on a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel rather than acting as a lock.

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 PB16X160SR Is Used
PCB Depaneling Ejector
Pushes singulated circuit boards out of a routing fixture with 100.5 N at 0.5 MPa, utilizing the slim barrel to fit between tight guide rails.
Carton Flap Folder
Tucks small corrugated flaps during case erecting, where the 160 mm stroke provides full reach and the R axial inlet keeps plumbing flush against the machine frame.
Sorter Diverter Arm
Actuates a lightweight paddle to deflect small plastic bottles on a packaging line, relying on the S magnet to trigger an electronic switch for stroke confirmation.
Is the Airtac PB Pen-type Cylinder PB16X160SR the Right Cylinder?
When sizing this actuator, the Ø12 bore steps down to 56.5 N push at 0.5 MPa, while this Ø16 provides 100.5 N at the same pressure, making it the top force option in the pen-size family with a 140.7 N maximum push at 0.7 MPa. Plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa figure) to account for seal friction, which equates to lifting about 5.1 kg vertically with a sane 2:1 margin.
Because the thin Ø5 mm rod is designed strictly for coaxial thrust, adding an external guide or linear bearing is recommended over this 160 mm stroke to prevent side-load binding. Note that a plain PB body does not hold its load if air pressure drops or the valve centers; the piston will drift, so an external rod lock is required for fail-safe positioning. Confirm your ordering essentials: 16 mm bore, 160 mm stroke, M5x0.8 port, S magnet, and R axial 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 PB16X160SR FAQ
At 0.5 MPa this 16 mm bore cylinder yields 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.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends and do not function as a brake. An external rod lock or mechanical stop is required to hold a load safely.
