Airtac PB Pen-type Cylinder PB10X50UFA
The AirTAC Airtac PB Pen-type Cylinder PB10X50UFA is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 50mm 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 PB10X50UFA
The AirTAC PB10X50UFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, providing excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 39.3 N of push force at 0.5 MPa, it uses an M5x0.8 air port and an M8x1.0 rod-end thread to couple securely to your load.
This specific configuration includes a U-type back cover for a 90-degree perpendicular air inlet, enabling flat plumbing in tight spaces, alongside an FA mounting bracket for secure body attachment. The bore uses fixed TPU bumpers at each end to decelerate the stroke over the final few millimeters. Because the rod is a slender Ø4 mm, you should maintain coaxial thrust and add an external guide if handling off-axis loads over the 50 mm travel.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 50 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 200 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 (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 PB10X50UFA Is Used
PCB Probe Testing
Drives delicate test probes onto printed circuit boards with a safe 24 N working load, ensuring contact without cracking the substrate.
Carton Flap Folding
Actuates small folding arms on a packaging line to tuck corrugated flaps, using the U-side inlet to keep hoses flush against the machine frame.
Light Pick-and-Place
Provides 50 mm of vertical stroke for a small pneumatic gripper lifting electronic components, keeping end-of-arm payload minimal.
Is the Airtac PB Pen-type Cylinder PB10X50UFA the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 24 N at 0.5 MPa, which is about 60% of its theoretical 39.3 N push rating to account for seal friction. If your vertical lift needs are higher, the next size up is the Ø12 bore delivering 56.5 N push at 0.5 MPa; if you need less force to fit an even tighter jig, step down to the Ø6 bore providing 14.2 N. To verify your ordering essentials for this model: confirm the 10 mm bore, 50 mm stroke, M5x0.8 port, U 90-degree side inlet, and FA mount. Note that a plain PB cylinder drifts when air is lost or the valve is centered, so an external rod lock is required for fail-safe position holding.
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 PB10X50UFA FAQ
This double-acting cylinder provides 39.3 N push and 33 N pull at 0.5 MPa, with a maximum force of 55 N push and 46.2 N pull at 0.7 MPa. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a maximum standard stroke of 200 mm for this 10 mm bore.
It uses fixed TPU bumpers at both ends to decelerate the stroke near the end of travel, which is not field-adjustable. For high-speed cycles with real tooling mass, meter-out the exhaust or add an external shock absorber. This version features a U-type 90-degree side inlet and an FA mounting bracket for flat surface installation.
