Airtac PB Pen-type Cylinder PB16X53SU
The AirTAC Airtac PB Pen-type Cylinder PB16X53SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 53mm 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 PB16X53SU
The AirTAC PB16X53SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 53mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This configuration includes a built-in piston magnet (-S) for position sensing with AirTAC reed or electronic switches, and a U-type back cover offering a 90-degree side air inlet for flat plumbing. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread. Deceleration is handled by a fixed TPU bumper at each end, which is not user-adjustable.

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 PB16X53SU Is Used
PCB Depaneling Router
Advances a cutting tool guide on an electronics assembly line, utilizing the 100.5 N push force to maintain steady positioning against router vibration.
Carton Flap Folder
Tucks small corrugated box flaps on a packaging conveyor, where the 90-degree U inlet keeps air lines flush against the machine frame to save space.
Lab Sample Dispenser
Actuates a small pipetting head in a wet analytical instrument, relying on the SUS304 stainless body to resist mild chemical exposure during fluid handling.
Is the Airtac PB Pen-type Cylinder PB16X53SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N (roughly 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. For vertical lifts, this equates to raising approximately 5.1 kg safely with a 2:1 margin. If you need slightly less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; if this is your maximum bore option, note that the Ø16 is the largest in this family.
The Ø5 mm piston rod is designed for coaxial thrust, so over the 53mm stroke avoid side loads or add an external linear guide. A plain PB cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. For fail-safe load holding, specify an external rod lock. To order, confirm the 16mm bore, 53mm stroke, S magnet, U side-inlet cover, and your preferred mounting bracket.
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 PB16X53SU 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 range of 50-800 mm/s.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; this is not an adjustable air cushion, so for high-speed loads you should meter-out the exhaust or add an external shock absorber. The built-in S magnet allows position detection using either AirTAC reed or electronic switches.
