Airtac PB Pen-type Cylinder PB16X240SU
The AirTAC Airtac PB Pen-type Cylinder PB16X240SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 240mm 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 PB16X240SU
The AirTAC PB16X240SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, peaking at 140.7 N extend force at the 0.7 MPa maximum operating pressure. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas, keeping end-of-arm tooling weight low.
This specific configuration includes a built-in piston magnet (S) for position detection using AirTAC reed or electronic switches, and a U-type back cover featuring a 90-degree perpendicular air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread are fixed by the 16 mm bore. Travel is managed by a fixed TPU bumper at each end, which decelerates the piston over the final few millimeters rather than acting as a lock.

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 PB16X240SU Is Used
PCB Depaneling Router
Pushes a carrier plate into the cutting bit on an automated depaneling machine, where the slim 16 mm barrel clears adjacent tooling and the 100.5 N thrust handles the feed.
Carton Flap Folder
Folds secondary corrugated flaps on a small case erector, using the 90-degree U inlet to keep plumbing flat against the machine frame in a tight packaging cell.
Sorter Diverter Arm
Actuates a lightweight paddle on a belt conveyor to reject off-spec small parts, relying on the S magnet to trigger an electronic switch for stroke confirmation.
Is the Airtac PB Pen-type Cylinder PB16X240SU 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. Vertically, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If you need less force, the adjacent 12 mm bore provides 56.5 N push at 0.5 MPa; stepping up is not applicable as 16 mm is the largest in this series. Because the 240 mm stroke is lengthy relative to the Ø5 mm rod, add an external linear bearing to prevent side-load deflection.
Confirm your ordering essentials: 16 mm bore, 240 mm stroke, M5x0.8 port, S magnet for sensors, U 90-degree side inlet, and no mounting bracket. Note that a standard PB body does not hold position when air is lost or the valve is centered—the piston drifts, so an external rod lock is required for fail-safe holding. At high cycling speeds with real tooling mass, the fixed bumper may bottom out, so meter-out the exhaust or add an external shock absorber.
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 PB16X240SU FAQ
The 16 mm bore yields 100.5 N push and 90.7 N pull at 0.5 MPa. At the 0.7 MPa maximum operating pressure, it produces 140.7 N push and 126.9 N pull. Operating pressure spans 0.15-0.7 MPa, with a speed range of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, a standard double-acting PB cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near stroke end and does not function as a brake. You must add an external rod lock or mechanical stop for fail-safe load holding.
