Airtac PB Pen-type Cylinder PB6X15R
The AirTAC Airtac PB Pen-type Cylinder PB6X15R is a double-acting pen-size (mini) air cylinder with a Ø6mm bore and 15mm 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 PB6X15R
The AirTAC PB6X15R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling extremely light. Delivering 14.2 N of push force at 0.5 MPa, it uses an M5x0.8 port and a fixed TPU bumper at each end to decelerate the stroke.
Because this configuration uses the R axial air inlet, plumbing runs straight in-line with the body for neat routing in tight spaces. The Ø3 mm piston rod provides coaxial thrust, and the unit operates at speeds from 50-800 mm/s with a maximum pressure of 0.7 MPa. Plan for a safe working load of roughly 9 N (about 60% of the 0.5 MPa rating) to account for seal friction and smooth travel.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 15 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 60 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 (Ø6mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 14.2 N | 10.6 N |
| 0.7 MPa (max) | 19.8 N | 14.8 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 PB6X15R Is Used
PCB Probe Testing
Drives delicate test probes onto printed circuit boards with just enough thrust to seat the pins without damaging the copper traces.
Blister Pack Sealing
Cycles a small heat seal head rapidly to close blister cavities, utilizing the compact stainless body to fit within narrow packaging dies.
Micro-Dispense Valving
Actuates a micro-dispense valve for precise adhesive dots, relying on the fast 50-800 mm/s response to meter exact shot volumes.
Is the Airtac PB Pen-type Cylinder PB6X15R the Right Cylinder?
This 6 mm bore steps neatly between the smaller Ø4 (6.3 N push at 0.5 MPa) and the larger Ø10 (39.3 N push at 0.5 MPa), letting you scale force precisely. If your application requires lifting a component vertically, this model handles about 0.7 kg safely with a 2:1 margin. Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered, so fit an external rod lock if you need fail-safe position holding.
When ordering, confirm the 6 mm bore, 15 mm stroke, M5x0.8 port, and the R axial inlet. This specific SKU does not include a sensor magnet; if you need position feedback, specify the -S option for a reed or electronic switch. The thin Ø3 mm rod is built for pure thrust, so add a linear bearing if your jig imposes any side load.
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 PB6X15R FAQ
At 0.5 MPa, the push force is 14.2 N and the pull force is 10.6 N. At the maximum operating pressure of 0.7 MPa, the push force is 19.8 N and the pull force is 14.8 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not adjustable or a locking brake. If you have real tooling mass at higher speeds, meter-out the exhaust or add an external shock absorber. Additionally, it will not hold a load if air pressure is lost; an external stop is required for fail-safe holding.
