Airtac B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU
The AirTAC Airtac B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU 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 B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU
The B52-PB10X40SU is a double-acting JIS pen-size mini cylinder from AirTAC's copper-free (copper-prohibited) build line, designed for applications where copper and copper alloys are not permitted, such as ammonia systems or certain battery and electronics plants. The B52- prefix marks this as the copper-free version of the PB10X40SU, with the same slim round stainless barrel and screwed-in covers that make it ideal for tight jigs and light end-of-arm tooling.
With a 10mm bore, this cylinder delivers 39.3 N of push force and 33 N of pull force at 0.5 MPa, rising to 55 N push and 46.2 N pull at the 0.7 MPa maximum. The SUS304 stainless piston rod and barrel resist damp or mildly corrosive environments, while the fixed TPU bumper at each end decelerates the piston in the final millimeters of travel-it is not adjustable, so plan for external shock absorption if you're moving real tooling mass at speed.

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 B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU Is Used
Battery Cell Assembly
In battery manufacturing lines where copper is prohibited, this 39.3N cylinder positions small cell components in a 40mm stroke with the U side inlet keeping plumbing flat against the fixture.
Electronics Pick-and-Place
The slim 10mm bore body fits between tight rails in PCB handling equipment, pushing light components into place at speeds up to 800 mm/s without the bulk of larger cylinders.
Ammonia System Valve Actuation
In chemical plants using ammonia, the copper-free B52 build prevents corrosion issues while the stainless rod and barrel handle the damp environment, actuating small valves with 33N retract force.
Is the Airtac B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU the Right Cylinder?
When sizing this B52-PB10X40SU, consider stepping down to the 6mm bore PB6 series if you need less force-it delivers 14.2 N push at 0.5 MPa. If you need more power, step up to the 12mm bore PB12 series, which provides 56.5 N push at 0.5 MPa. At 40mm stroke, this model is well within the 200mm maximum standard stroke for the 10mm bore.
For this model, confirm the bore (10mm), stroke (40mm), and M5x0.8 port. The -S suffix indicates a built-in magnet for AirTAC reed or electronic switches, and the U suffix specifies a 90-degree side air inlet for flat plumbing. Note that a plain PB-type cylinder does not hold its position when air pressure is lost-the piston drifts, and the bumper only decelerates it near stroke end. For fail-safe load holding, add an external stop or rod lock. The thin 4mm rod is designed for coaxial thrust only; avoid side loads and consider an external guide for long strokes.
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 B52-PB Copper-Free Pen-Type Cylinder B52-PB10X40SU FAQ
At 0.5 MPa, the push force is 39.3 N and pull force is 33 N. At the maximum 0.7 MPa operating pressure, push force reaches 55 N and pull force is 46.2 N. The maximum operating pressure is 0.7 MPa-never exceed this. For practical sizing, plan for about 24 N of real work at 0.5 MPa (60% of theoretical force), which translates to lifting roughly 2 kg vertically with a 2:1 safety margin.
