Airtac PB Pen-type Cylinder PB16X180SR
The AirTAC Airtac PB Pen-type Cylinder PB16X180SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 180mm 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 PB16X180SR
The AirTAC PB16X180SR is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. 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 to fit tight jig spaces while resisting damp or mildly corrosive environments. This 16 mm bore unit features an M5x0.8 port, an M10x1.0 rod-end thread, and a 180 mm stroke.
Equipped with a built-in piston magnet (S code), it supports AirTAC reed or electronic switches for precise position detection. The R axial inlet allows straightforward in-line plumbing. Travel is capped at a 50-800 mm/s speed range, with fixed TPU bumpers at both ends to absorb end-of-stroke impact. Plan for a safe working load of roughly 60 N at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a sane 2:1 safety margin.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 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 PB16X180SR Is Used
PCB Depaneling Router
Actuates a tooling arm to separate routed circuit boards, utilizing the 100.5 N push force to cleanly snap pre-scored tabs without stressing adjacent components.
Carton Flap Folder
Tucks minor flaps on small product cartons moving down a packaging line, where the compact stainless body resists washdown moisture and fits within tight side rails.
Lab Tube Ejection
Pushes capped sample tubes out of a testing carousel, using the S magnet to trigger a reed or electronic switch that confirms the 180 mm ejection stroke is fully complete.
Is the Airtac PB Pen-type Cylinder PB16X180SR the Right Cylinder?
Choosing this 16 mm bore means sizing against its neighbours: step down to a 12 mm bore for 56.5 N push at 0.5 MPa, or step up if you need more power since 16 mm is the largest in this pen-size family, offering 100.5 N push at 0.5 MPa. Confirm your ordering essentials: 16 mm bore, 180 mm stroke, R axial back cover, S magnet, and M5x0.8 porting.
Keep in mind that a plain PB-type cylinder does not hold its load if air pressure drops or the valve is centred—the piston will drift. For fail-safe holding, an external stop or rod lock is required. Additionally, the Ø5 mm rod is built for coaxial thrust; over this 180 mm stroke, adding an external guide or linear bearing prevents side-load binding.
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 PB16X180SR 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 fixed TPU bumpers at both ends that decelerate the piston over the last few millimeters; these are not adjustable, so metering out the exhaust or adding an external shock absorber is recommended for high-mass loads. The cylinder does not hold position on air loss, so an external rod lock is needed for fail-safe vertical holding.
