Airtac PB Pen-type Cylinder PB10X25R
The AirTAC Airtac PB Pen-type Cylinder PB10X25R is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 25mm 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 PB10X25R
The AirTAC PB10X25R is a JIS pen-size double-acting single-rod mini cylinder engineered for high-frequency small-part motion. It delivers 39.3 N of push and 33 N of pull at 0.5 MPa, utilizing a 4 mm piston rod with an M8x1.0 rod-end thread. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas while saving valuable space on end-of-arm tooling.
This 10 mm bore unit features an R axial air inlet for in-line plumbing and uses an M5x0.8 port. It relies on a fixed TPU bumper at each end to decelerate the stroke over the final few millimeters. Because the bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when cycling heavier tooling masses at higher speeds.

| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PB10X25R Is Used
PCB Depaneling Jig
Actuates a small cutting blade on an electronics assembly line, where the slim 10 mm body fits between densely packed routing fixtures and the 39.3 N thrust cleanly separates routed boards.
Carton Flap Folder
Tucks minor flaps on a compact packaging conveyor using the R axial inlet for flush in-line plumbing, keeping the actuator profile clear of passing cardboard cartons.
Lab Sample Dispenser
Drives a micro-pipette tip into a reagent tray, benefiting from the SUS304 stainless construction that withstands humid laboratory environments and repeated chemical wipe-downs.
Is the Airtac PB Pen-type Cylinder PB10X25R the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N (roughly 60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. In a vertical lift scenario, this translates to lifting about 2 kg with a sane 2:1 safety margin. If your application requires slightly less force, the Ø6 bore provides 14.2 N push at 0.5 MPa; stepping up to the Ø12 bore yields 56.5 N push at 0.5 MPa. Note that a plain PB cylinder 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.
Confirm your ordering essentials: 10 mm bore, 25 mm stroke, M5x0.8 porting, no sensor magnet, and the R axial inlet. The thin 4 mm rod is designed strictly for coaxial thrust; over this 25 mm stroke, avoid side loading or add a linear bearing to prevent rod binding.
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 PB10X25R FAQ
At 0.5 MPa, the push force is 39.3 N and the pull force is 33 N. At the maximum operating pressure of 0.7 MPa, the push force is 55 N and the pull force is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end; it does not act as a lock or brake. An external rod lock or mechanical stop is required for fail-safe load holding.
