Airtac PB Pen-type Cylinder PB16X300SR
The AirTAC Airtac PB Pen-type Cylinder PB16X300SR 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 PB16X300SR
The AirTAC PB16X300SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight. Delivering 100.5 N of push force at 0.5 MPa, this model integrates an R axial air inlet for in-line plumbing and a built-in piston magnet for position sensing.
Equipped with a 5 mm rod and an M10x1.0 rod-end thread, it uses an M5x0.8 port and reaches a maximum standard stroke of 300 mm. The cylinder relies on a fixed TPU bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Because the rod is only 5 mm thick, it is built for coaxial thrust over long strokes; adding an external linear bearing prevents side-load binding.

| 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 PB16X300SR Is Used
PCB Edge Guide Routing
Drives a low-friction linear guide to position printed circuit boards beneath a routing spindle, utilizing the 5.1 kg vertical lift capacity to raise and lower delicate panels safely.
Package Sorting Diverter
Extends 300 mm to push lightweight cardboard cartons from a main conveyor belt into a secondary packing lane, relying on the fixed TPU bumper to soften the rapid 800 mm/s impact.
Lab Sample Dispenser
Actuates a dosing probe in a wet analytical instrument, where the SUS304 stainless barrel resists chemical humidity and the compact pen-size body fits between dense reagent racks.
Is the Airtac PB Pen-type Cylinder PB16X300SR the Right Cylinder?
This 16 mm bore generates 100.5 N push at 0.5 MPa, yielding a safe working load of roughly 60 N for smooth travel. If you need less force, stepping down to the 12 mm bore provides 56.5 N push at 0.5 MPa. As the largest diameter in this series, there is no larger option available to step up to. For vertical lifts, plan for a maximum part weight of about 5.1 kg to maintain a sane 2:1 safety margin against gravity.
When ordering, confirm the 16 mm bore, 300 mm stroke, M5x0.8 port, and the R axial inlet configuration. The S suffix indicates the internal magnet is present for use with AirTAC reed or electronic switches. Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, so an external rod lock is required 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 PB16X300SR 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 proof pressure of 1.2 MPa, and the speed range is 50-800 mm/s.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not field-adjustable; for high-speed loads, meter-out the exhaust or add an external shock absorber. The S suffix denotes a built-in magnet compatible with AirTAC reed or electronic switches for precise position detection.
