Airtac PB Pen-type Cylinder PB10X40U
The AirTAC Airtac PB Pen-type Cylinder PB10X40U is a double-acting pen-size (mini) air cylinder with a Ø10mm 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 PB10X40U
The AirTAC PB10X40U is a JIS double-acting single-rod mini cylinder engineered for compact automation. It delivers 39.3 N of push force and 33 N of pull force at 0.5 MPa. The slim SUS304 stainless steel round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas while keeping end-of-arm tooling extremely light.
This 10 mm bore unit features a 4 mm rod, an M8x1.0 rod-end thread, and an M5x0.8 port. Equipped with a U-type back cover, it provides a 90-degree perpendicular air inlet for flat plumbing in space-constrained fixtures. A fixed TPU bumper at each end manages end-of-stroke energy, and the unit operates at speeds from 50-800 mm/s with a maximum pressure of 0.7 MPa.

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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PB10X40U Is Used
PCB Depaneling Jig
Advances a cutting blade on an electronic assembly line, where the slim stainless body fits between dense conveyor rails and the 39.3 N thrust cleanly separates routed boards.
Blister Pack Sealing
Closes a small heated platen on a pharmaceutical packaging machine, using the 90-degree U inlet to keep pneumatic tubing flush against the machine frame.
Lab Dispenser Actuation
Drives a micro-pump head in a fluid diagnostics device, benefiting from the fast 50-800 mm/s response and fixed TPU bumpers to prevent harsh mechanical impacts at stroke end.
Is the Airtac PB Pen-type Cylinder PB10X40U the Right Cylinder?
When sizing this actuator, consider stepping down to the 6 mm bore (14.2 N push at 0.5 MPa) for lighter electronic sorting tasks, or up to the 12 mm bore (56.5 N push at 0.5 MPa) if you need extra thrust. For the PB10X40U, plan for a safe working load of about 24 N, which is roughly 60 percent of the 0.5 MPa theoretical push to account for seal friction. This equates to lifting about 2 kg vertically with a sane 2:1 safety margin. Because the 4 mm rod is slender, always maintain coaxial alignment and add an external linear bearing for any off-axis loads over the 40 mm stroke. Note that a plain cylinder drifts when air is lost; install an external rod lock if your process requires fail-safe position holding. Confirm your ordering essentials: 10 mm bore, 40 mm stroke, U side inlet, no magnet, and M5x0.8 ports.
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 PB10X40U FAQ
This double-acting cylinder generates 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
This specific configuration lacks the internal magnet, so it cannot host AirTAC reed or electronic switches. Impact control relies entirely on a fixed TPU bumper at each end that decelerates the piston over the final few millimeters; it is not an adjustable air cushion, so meter-out the exhaust or add an external shock absorber for heavy high-speed tooling.
