Airtac PB Pen-type Cylinder PB16X300SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X300SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 300mm 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 PB16X300SCB
The AirTAC PB16X300SCB is a JIS pen-size double-acting single-rod mini cylinder, engineered to deliver 100.5 N of push force at 0.5 MPa. Its slim SUS304 stainless steel barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This specific configuration includes a built-in piston magnet for position sensing and a CB double clevis back cover for pivoting loads.
Featuring a 16 mm bore and a 300 mm stroke, this unit uses an M5x0.8 air port and an M10x1.0 rod-end thread. The Ø5 mm piston rod is designed for coaxial thrust; over this long 300 mm extension, adding an external linear bearing is highly recommended to prevent side-load damage. It operates at 50-800 mm/s with a fixed TPU bumper at each end to decelerate the piston near stroke limits.

| Stroke | 300 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 |

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 PB16X300SCB Is Used
Textile Loom Guide
Actuates a pivoting thread guide arm on a weaving machine, utilizing the CB double clevis to accommodate the swing arc while handling the 300 mm reach.
Package Sorting Diverter
Pushes lightweight cardboard cartons at 50-800 mm/s onto a secondary packaging line, where the fixed TPU bumper absorbs the end-of-stroke impact.
Lab Sample Dispenser
Extends a fluid nozzle across a 300 mm stroke to deposit reagents, benefiting from the SUS304 stainless build resisting humid laboratory conditions.
Is the Airtac PB Pen-type Cylinder PB16X300SCB the Right Cylinder?
When sizing this model, the PB12X30 offers a smaller footprint with 56.5 N push at 0.5 MPa, while stepping up is not possible as 16 mm is the largest bore in the PB family. For the PB16X300SCB, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction. In vertical lift applications, this equates to lifting about 5.1 kg safely with a 2:1 margin.
Because this is a double-acting cylinder, it will not hold its load if air pressure is lost or the valve is centered—the piston will drift. For fail-safe holding, an external rod lock or mechanical stop is required. Confirm your ordering essentials: 16 mm bore, 300 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and CB double clevis mounting.
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 PB16X300SCB 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 cylinder operates at 0.15-0.7 MPa with a speed range of 50-800 mm/s.
The -S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position detection. Cushioning is provided by a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so for high-speed loads you should meter-out the exhaust or add an external shock absorber.
