Airtac PB Pen-type Cylinder PB16X135SU
The AirTAC Airtac PB Pen-type Cylinder PB16X135SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 135mm 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 PB16X135SU
The AirTAC PB16X135SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It leverages a 16mm bore to generate 100.5 N of push force at 0.5 MPa, extending to a maximum 140.7 N at 0.7 MPa. The SUS304 stainless barrel and rod provide dependable resistance in damp or mildly corrosive work areas, while the slim round profile saves valuable space on tight jigs. This specific configuration includes a 90-degree side air inlet for flat plumbing and a built-in piston magnet.
Air enters via the M5x0.8 port, driving the Ø5 mm rod at speeds from 50 to 800 mm/s. End-of-stroke energy is managed by a fixed TPU bumper at each end, which decelerates the last few millimeters of travel. Because the bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher velocities. The included -S magnet enables position detection using AirTAC reed or electronic switches.

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 PB16X135SU Is Used
PCB Depaneling Router
Pushes a light cutting head or clamping fixture along a 135mm path in desktop electronics routing equipment, utilizing the slim stainless body to fit between dense tooling stations.
Carton Flap Folder
Actuates a folding arm on a small packaging line, relying on the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame without protruding.
Sorting Diverter Gate
Drives a lightweight diverter paddle to route small parcels on a conveyor, using the built-in magnet and AirTAC electronic switch to confirm stroke completion.
Is the Airtac PB Pen-type Cylinder PB16X135SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N (about 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 about 5.1 kg with a sane 2:1 safety margin. If you need less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; since Ø16 is the largest in this family, stepping up requires migrating to a larger profile series. Keep in mind the thin Ø5 mm rod is built for coaxial thrust, so over the 135 mm stroke an external linear bearing should be added if off-axis loads are present. A plain PB body does not hold its load if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16mm bore, 135mm stroke, M5x0.8 port, -S magnet, and U side 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 PB16X135SU FAQ
This 16mm bore double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa, reaching maximums of 140.7 N push and 126.9 N pull at the 0.7 MPa family pressure limit. It operates at 0.15-0.7 MPa with speeds of 50-800 mm/s, using an M5x0.8 port and a fixed TPU bumper at each end.
The U back cover provides a 90-degree perpendicular air inlet, allowing hoses to run flat against the machine for tight clearance situations. The fixed TPU bumpers only decelerate the rod over the final few millimeters of travel and cannot be field-adjusted, so for high-speed tooling mass you should meter-out the exhaust or install an external shock absorber.
