Airtac PB Pen-type Cylinder PB16X50SR
The AirTAC Airtac PB Pen-type Cylinder PB16X50SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 50mm 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 PB16X50SR
The AirTAC PB16X50SR 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 weight to an absolute minimum. Delivering 100.5 N of push force at 0.5 MPa, it provides robust thrust for its 16 mm footprint.
This specific configuration includes a built-in piston magnet (S) for position detection and an axial R back cover for in-line plumbing. Air connects via an M5x0.8 port, and the Ø5 mm rod utilizes an M10x1.0 end thread for secure load coupling. To manage impact, a fixed TPU bumper at each end decelerates the piston over the final few millimeters of travel.

| 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 PB16X50SR Is Used
PCB Depaneling Router
Provides the rigid 100.5 N thrust needed to push singulated circuit boards out of a routing fixture without stressing the delicate fiberglass substrate.
Carton Flap Folder
Extends rapidly at up to 800 mm/s to tuck minor flaps on small pharmaceutical cartons before the sealing head applies tape.
Lab Sample Ejector
Ejects filled blood vials from a centrifuge carousel, utilizing the SUS304 stainless construction to withstand frequent chemical wipe-downs.
Is the Airtac PB Pen-type Cylinder PB16X50SR the Right Cylinder?
When sizing this 16 mm bore actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, accounting for seal friction and smooth travel (about 60% of its 100.5 N theoretical output). For vertical lifts, this equates to safely raising around 5.1 kg with a 2:1 safety margin. If you need slightly less force, the 12 mm bore provides 56.5 N push at 0.5 MPa; if you require substantially more power, this 16 mm bore is the largest available in the PB pen-size family, delivering 140.7 N at its 0.7 MPa maximum.
Because the thin Ø5 mm rod is designed strictly for coaxial thrust, avoid side loads and add an external linear bearing for off-axis guiding over the 50 mm stroke. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift. For fail-safe load holding, an external rod lock or mechanical stop is required. Confirm your ordering essentials: 16 mm bore, 50 mm stroke, M5x0.8 port, S magnet, and R axial inlet.
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 PB16X50SR FAQ
This double-acting single-rod cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it generates 140.7 N push and 126.9 N pull. It operates on filtered air at 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The S designation means it has a built-in piston magnet compatible with AirTAC reed or electronic switches for position sensing. For motion control, it relies on a fixed TPU bumper at each end that only decelerates the last few millimeters of travel. If you are moving real tooling mass at high speed, you should meter-out the exhaust or add an external shock absorber, as the bumper is not adjustable.
