Airtac PB Pen-type Cylinder PB10X90U
The AirTAC Airtac PB Pen-type Cylinder PB10X90U is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 90mm 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 PB10X90U
The AirTAC PB10X90U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It delivers 39.3 N of push force and 33 N of pull force at 0.5 MPa, operating through a 90 mm stroke. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp production areas, while the M5x0.8 port keeps pneumatic plumbing compact.
This variant features a U-type back cover with a 90-degree perpendicular air inlet for flat side plumbing in space-constrained assemblies. Instead of an adjustable air cushion, it relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters. Because the rod is a slender 4 mm diameter, it is built for coaxial thrust rather than side loading, requiring an external guide if handling off-axis masses over the 90 mm travel.

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 PB10X90U Is Used
PCB Depaneling Router
Advances a cutting tool along a 90 mm path to singulate printed circuit boards, utilizing the 39.3 N push force and slim profile to fit within dense electronics manufacturing fixtures.
Carton Flap Folder
Tucks minor flaps on small packaging lines using the U-type 90-degree inlet to keep air hoses flush against the machine frame, avoiding snags in tight transfer corridors.
Lab Sample Dispenser
Actuates a small dosing valve for liquid reagents where the SUS304 stainless body resists humidity and chemical splashes common in analytical laboratory environments.
Is the Airtac PB Pen-type Cylinder PB10X90U the Right Cylinder?
When sizing this 10 mm bore actuator, stepping down to the 6 mm version yields 14.2 N of push at 0.5 MPa, while stepping up to the 12 mm bore provides 56.5 N, letting you match exact force needs. For the PB10X90U, confirm the 90 mm stroke, the U-type 90-degree side inlet, and the absence of a sensor magnet. Plan for a safe working load of about 24 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
A standard PB cylinder does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end. If your process requires a fail-safe hold under load, you must integrate an external stop or rod lock. For higher cycling speeds with real tooling mass, meter-out the exhaust or add an external shock absorber since the fixed bumpers can bottom out.
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 PB10X90U 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 of 50-800 mm/s and a proof pressure of 1.2 MPa.
The U-type back cover provides a 90-degree perpendicular air inlet for flat plumbing in confined spaces. Deceleration is handled by fixed TPU bumpers at both ends rather than adjustable cushions, meaning they only absorb impact over the final few millimeters of the 90 mm stroke and cannot be field-tuned.
