Airtac PB Pen-type Cylinder PB10X40SUFA
The AirTAC Airtac PB Pen-type Cylinder PB10X40SUFA is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 40mm 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 PB10X40SUFA
The AirTAC PB10X40SUFA is a JIS double-acting single-rod pen-size mini cylinder engineered for tight jigs and light end-of-arm tooling. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding unnecessary payload. Delivering 39.3 N of push and 33 N of pull at 0.5 MPa, it provides reliable small-part actuation.
This configuration includes a built-in piston magnet for position sensing, a U-type 90-degree side air inlet for flat plumbing, and an FA mounting bracket. The Ø4 mm rod utilizes an M8x1.0 rod-end thread, while the body ports accept M5x0.8 fittings. Deceleration is handled by a fixed TPU bumper at each end, which is not adjustable, so high-speed cycles with real tooling mass may require metering out the exhaust or adding an external shock absorber.

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 PB10X40SUFA Is Used
PCB Pick-and-Place
Drives lightweight vacuum grippers in electronics assembly, using the 39.3 N extend force to lift delicate boards while the FA bracket secures the body to the gantry.
Label Dispensing Arm
Actuates a small labeling head in a packaging line, where the U 90-degree side inlet keeps pneumatic tubing flush against the machine frame to save space.
Lab Sample Ejection
Pushes vials out of a centrifuge carousel, relying on the SUS304 stainless construction to withstand humid laboratory conditions and repeated high-frequency cycles.
Is the Airtac PB Pen-type Cylinder PB10X40SUFA the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N, which is roughly 60% of the 39.3 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. For vertical lifts, this equates to raising approximately 2 kg with a sane 2:1 safety margin. If you need less force, the Ø6 bore provides 14.2 N of push at 0.5 MPa; stepping up to the Ø12 bore yields 56.5 N.
Because the slender Ø4 mm rod is designed strictly for coaxial thrust, avoid side loads and add an external linear bearing if guiding off-axis loads over the 40 mm stroke. A plain double-acting cylinder drifts when air is lost or the valve is centered, so integrate an external rod lock if your application must hold a load safely without live pressure. Confirm your ordering essentials: 10 mm bore, 40 mm stroke, S magnet, U side inlet, and FA mount.
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 PB10X40SUFA FAQ
At 0.5 MPa, this 10 mm bore cylinder generates 39.3 N of push and 33 N of pull. At the maximum operating pressure of 0.7 MPa, it generates 55 N of push and 46.2 N of pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, a standard double-acting cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a brake. You must use an external rod lock or mechanical stop to hold a load safely without live pressure.
