Airtac PB Pen-type Cylinder PB16X45SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X45SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 45mm 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 PB16X45SCB
The AirTAC PB16X45SCB is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency automation. It features a SUS304 stainless steel slim round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, this model is the largest bore in the PB family.
This specific configuration includes a built-in piston magnet (S) for position sensing and a CB double clevis back cover for pivoting loads. Air connections utilize an M5x0.8 port. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high speeds.

| Rod diameter | Ø5 mm |
| Stroke | 45 mm |
| 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

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 PB16X45SCB Is Used
PCB Depanelling Ejector
Pushes separated circuit boards out of a routing fixture with precise 45mm travel, utilizing the CB clevis to pivot with any slight misalignment.
Carton Flap Folder
Folds small corrugated carton flaps at high speed on a packaging line, where the SUS304 body withstands occasional washdowns and the fixed TPU bumper absorbs end-of-stroke impacts.
Sorter Diverter Arm
Actuates a lightweight routing gate to deflect small parcels on a conveyor, relying on the built-in S magnet to confirm gate position via a reed or electronic switch.
Is the Airtac PB Pen-type Cylinder PB16X45SCB the Right Cylinder?
Selecting the PB16X45SCB places you at the top of the PB family's force range. If you need slightly less thrust, the next bore down is the Ø12, which provides 56.5 N of push at 0.5 MPa. As the largest standard option, there is no larger bore up in this series. Plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
When sizing your vertical lift, expect to handle about 5.1 kg safely with a 2:1 margin. Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered; the bumper only decelerates near stroke end and does not lock the load, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16mm bore, 45mm stroke, M5x0.8 port, S magnet, and CB clevis.
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 PB16X45SCB 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 force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
No, a plain double-acting cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end; it does not act as a lock or brake. An external rod lock or mechanical stop is required for fail-safe load holding.
