Airtac PB Pen-type Cylinder PB4X15
The AirTAC Airtac PB Pen-type Cylinder PB4X15 is a double-acting pen-size (mini) air cylinder with a Ø4mm bore and 15mm 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 PB4X15
The AirTAC PB4X15 is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It delivers 6.3 N of push and 4.7 N of pull at 0.5 MPa, operating via an M3x0.5 tube fitting port. The slim round body pairs a bronze barrel with a stainless steel piston rod, offering reliable durability in damp or mildly corrosive workspaces.
This 4 mm bore unit travels 15 mm and contains no end cushion, relying solely on the external system to manage stop energy. Because the rod is just 2 mm in diameter, it is built strictly for coaxial thrust; operators should add an external guide if any off-axis load is present to prevent bending.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø4 mm |
| Rod diameter | Ø2 mm |
| Stroke | 15 mm |
| Acting type | Double acting |
| Port size | M3×0.5 (tube) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | No cushion |
| Max standard stroke | Up to 20 mm |
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 PB4X15 Is Used
Micro-clip insertion
Drives a 2 mm rod to push delicate electronic clips into PCB sockets without overwhelming the fragile 4 N working load limit.
Lab reagent positioning
Shifts light polymer sample trays 15 mm in damp analytical equipment, leveraging the bronze and stainless build to resist humidity.
Tiny sensor sorting
Ejects miniature optical sensors from a test nest, where the compact pen-size body saves critical space on a dense packaging carousel.
Is the Airtac PB Pen-type Cylinder PB4X15 the Right Cylinder?
If your task requires slightly more force, the next size up is the Ø6 bore, which provides 14.2 N of push at 0.5 MPa; as the smallest bore in the family, Ø4 has no step down.
A plain PB-type cylinder does not hold its position if air pressure drops or the valve is centered, so an external stop or rod lock is required for fail-safe load holding. To order, confirm the 4 mm bore, 15 mm stroke, M3x0.5 tube fitting port, absence of a sensor magnet, and the standard axial inlet configuration.
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 PB4X15 FAQ
At 0.5 MPa, the push force is 6.3 N and the pull force is 4.7 N. At the maximum operating pressure of 0.7 MPa, the push is 8.8 N and the pull is 6.6 N. The cylinder operates at 0.2-0.7 MPa with a speed range of 50-500 mm/s.
The 4 mm bore has no end cushion or bumper, so external deceleration must be managed by the system. This specific configuration also lacks a sensor magnet, meaning position detection is not possible without modifying the build.
