Airtac PB Pen-type Cylinder PB16X115SU
The AirTAC Airtac PB Pen-type Cylinder PB16X115SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 115mm 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 PB16X115SU
The AirTAC PB16X115SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 115mm 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 excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This specific configuration includes a built-in piston magnet for position sensing with AirTAC reed or electronic switches, and a U-type back cover offering a 90-degree perpendicular air inlet for flat plumbing. Operating at speeds from 50-800 mm/s, it uses an M5x0.8 port and a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is not adjustable, adding an external shock absorber is recommended when moving heavy tooling at high velocities.

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 PB16X115SU Is Used
PCB Depaneling Router
Provides the precise coaxial thrust needed to clamp populated circuit boards during automated routing and cutting processes.
Blister Pack Sealing
Cycles rapidly to press heated lids onto thermoformed blister trays, utilizing the 90-degree side inlet to keep plumbing flat against the machine frame.
Diverter Gate Actuation
Drives lightweight sorting flaps on packaging lines, where the stainless build resists washdown moisture and the compact body fits tight transfer zones.
Is the Airtac PB Pen-type Cylinder PB16X115SU the Right Cylinder?
When sizing this actuator, note that the 16mm bore sits at the top of the PB family range. If your application requires less force, stepping down to the 12mm bore provides 56.5 N of push at 0.5 MPa. If you need the maximum thrust available in this series, the 16mm bore delivers 140.7 N at the 0.7 MPa maximum operating pressure. For real-world work at 0.5 MPa, plan for a safe working load of about 60 N to account for seal friction and smooth travel.
Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the internal bumper only decelerates near the stroke end rather than locking the rod. For vertical lifting, this actuator handles roughly 5.1 kg safely with a 2:1 margin. To order, confirm the 16mm bore, 115mm stroke, M5x0.8 port, S magnet, and U 90-degree 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 PB16X115SU 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 a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of the stroke and does not act as a locking brake. For fail-safe vertical holding, you must install an external rod lock or mechanical stop.
