Airtac PB Pen-type Cylinder PB6X30R
The AirTAC Airtac PB Pen-type Cylinder PB6X30R is a double-acting pen-size (mini) air cylinder with a Ø6mm bore and 30mm 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 PB6X30R
The AirTAC PB6X30R is a double-acting JIS pen-size mini cylinder engineered for high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering reliable durability in damp or mildly corrosive environments without adding unnecessary bulk. Delivering 14.2 N of push force at 0.5 MPa, it uses an M5x0.8 port and an R axial inlet for straightforward in-line plumbing.
This model relies on a fixed TPU bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Because the piston rod is a slender Ø3 mm, it is built for pure coaxial thrust; if your assembly involves off-axis loads, pairing it with an external linear bearing prevents side-load wear. For position feedback, note this specific unit lacks the internal magnet.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 30 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 PB6X30R Is Used
PCB Probe Testing
Drives delicate test pins onto printed circuit boards, where the compact 6 mm barrel fits between dense connector arrays and the 14.2 N output prevents trace damage.
Small Parts Diversion
Pushes lightweight plastic caps or vials across a packaging conveyor, utilizing the 30 mm stroke and R axial inlet to keep pneumatic plumbing flush against the machine frame.
Lab Dispenser Actuation
Cycles precision fluid valves in automated liquid handling stations, taking advantage of the SUS304 build to resist humid laboratory environments.
Is the Airtac PB Pen-type Cylinder PB6X30R the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 9 N at 0.5 MPa, which accounts for seal friction and smooth travel. If you need to lift a part vertically, keep the mass at or below 0.7 kg to maintain a sane 2:1 safety margin against gravity. If your application requires slightly less force, the Ø4 bore provides 6.3 N of push at 0.5 MPa, whereas stepping up to the Ø10 bore yields 39.3 N for heavier tooling.
Confirm your ordering essentials before checkout: this configuration specifies a 6 mm bore, 30 mm stroke, M5x0.8 porting, an R axial back cover, and no sensor magnet. A plain double-acting cylinder like this will drift and cannot hold a load if air pressure drops or the valve is centred, so incorporate an external rod lock or mechanical stop if fail-safe holding is required.
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 PB6X30R FAQ
This double-acting cylinder delivers a push force of 14.2 N and a pull force of 10.6 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push force is 19.8 N and the pull force is 14.8 N. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and uses an M5x0.8 port.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; it is not an adjustable air cushion, so you may need an external shock absorber for high-speed heavy masses. Additionally, it does not hold position on air loss—the piston will drift, requiring an external stop for fail-safe load holding.
