Airtac PB Pen-type Cylinder PB16X40SR
The AirTAC Airtac PB Pen-type Cylinder PB16X40SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 40mm 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 PB16X40SR
The AirTAC PB16X40SR is a JIS pen-size double-acting single-rod mini cylinder built for tight spaces and high-frequency small-part motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod that shrugs off damp or mildly corrosive environments. The integrated R axial inlet keeps plumbing perfectly in line with the body.
This 16 mm bore unit features a built-in S magnet for position detection via AirTAC reed or electronic switches. End-of-stroke energy is managed by a fixed TPU bumper at each end rather than an adjustable air cushion, meaning it only decelerates the final few millimeters of travel. With an M5x0.8 port and a 50-800 mm/s speed range, it provides rapid, compact actuation for light end-of-arm tooling.

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 PB16X40SR Is Used
PCB Depaneling Jig
Drives a small cutting blade or clamping finger in a tight electronics assembly cell, using the S magnet to confirm the retracted position before the conveyor advances.
Pouch Sealing Clamp
Applies 60 N of safe clamping force on a thin film packaging line, where the SUS304 stainless barrel withstands washdown cycles and the R axial port keeps hoses flat against the machine frame.
Textile Yarn Guide
Shifts a lightweight thread guide rapidly across a weaving loom, relying on the fixed TPU bumpers to absorb the impact of 50-800 mm/s cycling without requiring bulky shock hardware.
Is the Airtac PB Pen-type Cylinder PB16X40SR the Right Cylinder?
This 16 mm bore provides the highest standard force in the PB pen-size family, pushing 100.5 N at 0.5 MPa. If you need slightly less force, step down to the 12 mm bore which yields 56.5 N of push at 0.5 MPa. For sizing, plan for a safe working load of about 60 N (roughly 60 percent of the 0.5 MPa theoretical force) to account for seal friction and smooth travel, or expect to lift about 5.1 kg vertically with a sane 2:1 safety margin. Remember that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe holding.
When ordering, confirm the 16 mm bore, 40 mm stroke, M5x0.8 porting, the S magnet for sensing, and the R axial back cover. The Ø5 mm piston rod uses an M10x1.0 rod-end thread; because the rod is slender, always maintain coaxial thrust and add an external linear bearing if the application involves off-axis loads or long strokes.
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 PB16X40SR FAQ
At 0.5 MPa this 16 mm bore cylinder pushes with 100.5 N and pulls with 90.7 N. At the maximum operating pressure of 0.7 MPa, it pushes 140.7 N and pulls 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa, and it operates at speeds between 50 and 800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston only over the last few millimeters of travel; it is not an adjustable air cushion. If cycling at high speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, the bumper is not a lock, so the cylinder will drift and cannot hold a load if air pressure is lost.
