About the Airtac PB Pen-type Cylinder PB6X25R
The AirTAC PB6X25R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, providing excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your jig. Delivering 14.2 N of push force at 0.5 MPa, it occupies minimal space on end-of-arm tooling where a standard round body simply will not fit.
This specific configuration uses an R axial air inlet for straightforward in-line plumbing and an M5x0.8 port. The bore dictates a Ø3 mm rod with an M5x0.8 rod-end thread, ensuring secure coupling to your load. To manage impact, a fixed TPU bumper sits at each end to decelerate the piston over the final few millimeters of travel. Because this unit lacks a sensor magnet, position verification requires an external mechanical limit switch.

| Stroke | 25 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 |

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 PB6X25R Is Used
PCB Pick-and-Place
Drives a tiny vacuum nozzle in electronics assembly, utilizing its 14.2 N push force to lift delicate circuit boards without stressing the surface mount components.
Blister Pack Sealing
Actuates a small heat-sealing head inside a densely packed pharmaceutical packaging line, where the slim stainless body resists humidity and fits between guide rails.
Lab Dispenser Valve
Toggles a micro-dispense valve for reagent routing, using the 25 mm stroke to precisely meter fluid while the R axial inlet keeps pneumatic tubing neatly oriented.
Is the Airtac PB Pen-type Cylinder PB6X25R the Right Cylinder?
When sizing this actuator, stepping down to a Ø4 bore yields 6.3 N of push at 0.5 MPa, while stepping up to a Ø10 bore provides 39.3 N. Keep in mind 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 rod lock is necessary for fail-safe holding.
Confirm your ordering essentials before checkout: this model features a 6 mm bore, 25 mm stroke, M5x0.8 porting, an R axial back cover for in-line tubing, and no built-in magnet. The thin Ø3 mm rod is designed strictly for coaxial thrust, so if your stroke length increases or the load shifts off-axis, incorporate an external linear bearing to prevent side-load damage.
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 PB6X25R 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 speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
It relies on a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion. If operating at high speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold its load on air loss—the piston drifts, requiring an external stop for fail-safe positioning.
