Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X100SCM
The AirTAC Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X100SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 100mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X100SCM
This B52-MI25X100SCM is the copper-free (copper-prohibited) build of AirTAC's MI25X100SCM round-body mini cylinder. The stainless-steel barrel and rod resist mild corrosion and washdown, while the riveted construction keeps the body compact and light. With a 25 mm bore, it delivers 245.3 N of push force at 0.5 MPa, making it a solid choice for light assembly tasks.
The B52- prefix means this version is built for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery and electronics plants. The -S suffix adds a built-in piston magnet, enabling CMSG, DMSG, or EMSG switches for position sensing. The 1/8" port and M10x1.25 rod thread follow the ISO 6432 standard for 25, so it drops into standard mini-cylinder brackets and clevises. For a typical application, plan for about 147 N of safe working load at 0.5 MPa, which gives you a 2:1 margin over the rated force.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X100SCM Is Used
Battery Assembly Jigs
Use this copper-free cylinder in battery cell stacking jigs where copper contamination is prohibited. The 245 N push force at 0.5 MPa is enough to clamp thin electrode layers without damage, and the stainless build resists electrolyte splash.
Ammonia Leak Test Rigs
In ammonia-based refrigeration test stands, copper alloys corrode rapidly. This B52 version avoids that risk entirely. The 206 N pull force at 0.5 MPa can retract a small probe or valve stem reliably in a cyclic test fixture.
Electronics Conveyor Stop
On a PCB assembly line, mount this cylinder to raise a stopper pin. The 245 N push force lifts a lightweight aluminium stop block repeatedly, and the -S magnet lets a PLC confirm the pin position via a DMSG switch.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X100SCM the Right Cylinder?
When sizing this cylinder, compare it with the 20 MI (157 N push at 0.5 MPa) if you need a smaller footprint, or step up to the 32 MI (402.2 N push) for significantly more force. The 100 mm stroke is within the standard 500 mm maximum for this bore, so no special ordering is needed. Since this is a plain double-acting cylinder, it will not hold its position if air pressure is lost or the valve is centred-for a held load, add an external rod lock or a pilot-operated check valve. The fixed TPU bumper pads only soften the stroke end; they do not act as a brake. The CM back cover provides a round-end mounting style, and you can pair this with LB foot, FA flange, SDB pivot-block, or TC trunnion mounts. The built-in magnet (-S) works with CMSG, DMSG, or EMSG sensors. For a 100 mm stroke, keep side loads low to avoid rod bending.
Quick checklist

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
