Airtac PB Pen-type Cylinder PB4X10
The AirTAC Airtac PB Pen-type Cylinder PB4X10 is a double-acting pen-size (mini) air cylinder with a Ø4mm bore and 10mm stroke. Its slim round barrel and back cover are stainless steel, the M3×0.5 (tube) ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB4X10
The AirTAC PB4X10 is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It generates a 6.3 N push and 4.7 N pull at 0.5 MPa, utilizing a slim bronze barrel paired with a stainless piston rod to resist damp or mildly corrosive production lines. The Ø2 mm rod end features an M4x0.7 thread for straightforward load coupling.
Designed without any end cushion, this 10 mm stroke unit relies on precise coaxial thrust rather than shock absorption. It operates at speeds between 50-500 mm/s and uses an M3x0.5 small tube fitting for pneumatic plumbing. Its minimal footprint drastically reduces payload on light end-of-arm tooling where larger actuators would cause inertia issues.

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 (Ø4mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6.3 N | 4.7 N |
| 0.7 MPa (max) | 8.8 N | 6.6 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 PB4X10 Is Used
Micro-Gripper Actuation
Drives the tiny jaws inside semiconductor wafer handling grippers, providing the 6.3 N extension needed to pick delicate silicon dies without adding bulk to the end-of-arm tooling.
Lab Dispenser Pinching
Pinches flexible silicone tubing on automated diagnostic fluid lines, using its 10 mm stroke to accurately halt reagent flow in compact benchtop analyzers.
PCB Probe Positioning
Moves fine-pitch test probes into contact with printed circuit boards during in-circuit testing, where the lightweight bronze barrel minimizes inertia on high-speed XY gantries.
Is the Airtac PB Pen-type Cylinder PB4X10 the Right Cylinder?
When sizing this Ø4 actuator, the next step up is the Ø6 bore, which provides a 14.2 N push at 0.5 MPa—more than double the force for heavier gripping tasks. Because the PB4X10 sits at the smallest bore edge of the series, there is no smaller standard option. Plan for a safe working load of roughly 4 N (about 60 percent of the 6.3 N theoretical figure) to account for seal friction and smooth travel. In practical lifting terms, expect to move about 0.3 kg vertically with a sane 2:1 safety margin.
Confirm your ordering essentials before checkout: 4 mm bore, 10 mm stroke, M3x0.5 tube fitting port, no sensor magnet, and standard axial inlet. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external stop or rod lock is required for fail-safe holding. Additionally, the thin Ø2 mm rod is built strictly for coaxial thrust—avoid side loading and add an external linear bearing if the stroke demands guidance.
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 0.2 – 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 PB4X10 FAQ
The PB4X10 delivers a push force of 6.3 N and a pull force of 4.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push is 8.8 N and the pull is 6.6 N. It operates between 0.2-0.7 MPa at speeds of 50-500 mm/s, with a proof pressure of 1.2 MPa.
No, the Ø4 bore has no end cushion or bumper at all, so external shock absorption must be added for high-energy stops. This specific model also lacks the internal magnet required for AirTAC position switches; you would need an -S suffix variant for reed or electronic sensor feedback.
