Airtac PB Pen-type Cylinder PB16X20SUFA
The AirTAC Airtac PB Pen-type Cylinder PB16X20SUFA is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 20mm 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 PB16X20SUFA
The AirTAC PB16X20SUFA is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 20mm stroke, generating 100.5 N of push force at 0.5 MPa and a maximum of 140.7 N at 0.7 MPa. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while saving valuable space on light end-of-arm tooling.
This specific configuration includes a built-in piston magnet (-S) for position sensing, a U-type 90-degree perpendicular side air inlet for flat plumbing, and an FA mounting bracket. It uses an M5x0.8 port and an M10x1.0 rod-end thread. The unit relies on a fixed TPU bumper at each end for end-of-stroke deceleration, operating at speeds of 50-800 mm/s.

| 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 PB16X20SUFA Is Used
PCB Depaneling Router
Provides the rigid 100.5 N thrust at 0.5 MPa needed to plunge a small routing spindle into assembled printed circuit boards without taking up excessive equipment footprint.
Carton Flap Folder
Uses the 90-degree U inlet and FA bracket to tuck minor flaps on small packaging lines, fitting neatly within tight conveyor side frames.
Lab Dispense Head
Drives a metered valve for precise adhesive extrusion, where the SUS304 body resists humid cleanroom conditions and the S magnet confirms stroke endpoints.
Is the Airtac PB Pen-type Cylinder PB16X20SUFA the Right Cylinder?
When sizing this 16mm bore actuator, stepping down to a 12mm bore yields 56.5 N push at 0.5 MPa, while stepping up is not available as this is the largest diameter in the PB family. For the PB16X20SUFA, plan for a safe working load of about 60 N (roughly 60% of the 100.5 N theoretical force at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift scenarios, this equates to lifting about 5.1 kg safely with a 2:1 margin.
Because the fixed TPU bumper only decelerates the last few millimeters, adding an external shock absorber is advised if moving real tooling mass at high speeds. A plain double-acting cylinder drifts when air is lost or the valve is centered, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16mm bore, 20mm stroke, M5x0.8 port, S magnet, U side inlet, and FA mount.
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 PB16X20SUFA FAQ
This double-acting 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 yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s, with a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston, which is not field-adjustable; for heavy loads, meter-out the exhaust or add an external shock. The built-in S magnet allows tracking by AirTAC reed or electronic switches.
