The AirTAC Airtac B52-PB Copper-Free Pen-Type Cylinder B52-PB10X100SU is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 100mm 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.
The B52-PB10X100SU is a double-acting JIS pen-size mini cylinder with a 10mm bore and 100mm stroke, generating 39.3N of push force at 0.5MPa. The 'B52-' prefix designates AirTAC's copper-free (copper-prohibited) build, making it suitable for lines where copper alloys are not permitted, such as ammonia systems and certain battery or electronics plants. This version shares all dimensional and performance specs with the standard PB10X100SU, but the exact material substitutions should be confirmed with us.
Its slim round body is crafted from SUS304 stainless steel, offering a space-saving profile for tight jigs and light end-of-arm tooling while resisting damp or mildly corrosive environments. The fixed TPU bumper at each end decelerates the piston in the final millimeters of travel, but it is not adjustable, so for high-speed applications with real tooling mass, consider 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.
| 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.

In battery manufacturing, where copper is prohibited, this copper-free cylinder actuates light guide rails or positioning pins on assembly fixtures, using its 39.3N push to move small cell components without risking contamination.
For ammonia-based cooling or chemical dosing systems, the stainless build and copper-free construction allow this cylinder to operate a small valve stem, providing precise 100mm linear motion in a corrosive environment.
On a pharmaceutical blister line, this compact cylinder ejects rejected tablets from a conveyor pocket. Its 100mm stroke and fast 50-800 mm/s speed clear the part quickly, while the slim body fits between tight machine frames.
For sizing, this 10mm bore cylinder delivers 39.3N push at 0.5MPa. If you need more force, step up to the 12mm bore which provides 56.5N push at the same pressure; if you need less, the 6mm bore offers 14.2N push. With a 100mm stroke, this model is within the 200mm maximum standard stroke for the 10mm bore. The M5x0.8 port is standard for this bore size, and the rod-end thread is M8x1.0.
This unit includes the -S magnet for use with AirTAC reed or electronic switches, and features a U-type 90-degree side air inlet for flat plumbing. Remember that a plain PB-type cylinder does not hold its position when air pressure is lost or the valve is centered-the piston will drift. For applications requiring a fail-safe hold, you'll need an external stop or rod lock. The thin 4mm rod is designed for coaxial thrust; over long strokes or with off-axis loads, add an external guide or linear bearing.
Quick checklist
At 0.5 MPa, the push force is 39.3N and the pull force is 33N. At the maximum operating pressure of 0.7 MPa, push is 55N and pull is 46.2N. The maximum operating pressure for this family is 0.7 MPa, not 1.0 MPa. For a safe working load, plan for about 24N of real work at 0.5 MPa, which accounts for seal friction and smooth travel.
The 'B52-' prefix designates AirTAC's copper-free (copper-prohibited) build, intended for lines where copper and copper alloys are not allowed, such as ammonia systems or certain electronics plants. The exact material substitutions should be confirmed with us. This model includes the -S magnet for reed or electronic switches and a U-type 90-degree side air inlet. The fixed TPU bumper at each end decelerates the piston only in the last few millimeters-it is not a lock or brake.
