Airtac PB Pen-type Cylinder PB16X160SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X160SCB 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 PB16X160SCB
The AirTAC PB16X160SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and piston rod to resist damp or mildly corrosive environments. Plumb the M5x0.8 air ports to drive the 5 mm rod at speeds between 50-800 mm/s.
This 16 mm bore unit features a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches, and a CB double clevis back cover for pivoting loads. End-of-stroke deceleration relies on fixed TPU bumpers, which are not field-adjustable. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa push force), allowing you to lift approximately 5.1 kg vertically with a sane 2:1 margin.

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 PB16X160SCB Is Used
Package Diverter Flap
Pivots a lightweight sorting gate on a packaging conveyor to route small cartons, using the CB double clevis to swing the flap smoothly under 100.5 N of thrust.
PCB Test Fixture
Drives a probe head down onto printed circuit boards, relying on the -S magnet and an electronic switch to confirm the exact 160 mm extension before electrical contact.
Bin Lid Actuation
Opens and closes small parts bin lids on an automated storage carousel, where the SUS304 barrel withstands occasional humidity and the pen-size body saves overhead space.
Is the Airtac PB Pen-type Cylinder PB16X160SCB the Right Cylinder?
Selecting this 16 mm bore model provides the highest standard force tier in the PB family, stepping up from the 12 mm bore (56.5 N push at 0.5 MPa). If your application requires less force and a smaller footprint, the 10 mm bore offers 39.3 N push. Confirm your ordering essentials: 16 mm bore, 160 mm stroke, M5x0.8 port, S magnet, and CB double clevis.
Because the CB clevis accommodates pivoting articulation, ensure your linkage prevents severe side loading on the 5 mm rod—over a 160 mm stroke, add an external linear bearing if the load cannot stay perfectly coaxial. Note that a plain PB-type does not hold its load on air loss or valve centred; the piston drifts and the bumper only decelerates near stroke end, so install an external rod lock for fail-safe holding.
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 PB16X160SCB 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.
No, a plain PB-type cylinder does not hold its position if air is lost or the valve is centred; the piston will drift. The fixed TPU bumper at each end only decelerates the rod near the stroke limits and does not act as a brake. You must add an external rod lock or mechanical stop for fail-safe load holding.
