Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X60SCM
The AirTAC Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X60SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 60mm 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-MI25X60SCM
The B52-MI25X60SCM is the copper-free (copper-prohibited) version of AirTAC's MI25X60SCM, a round-body, double-acting mini cylinder with a stainless-steel barrel and rod. The 25mm bore delivers 245.3N of push force at 0.5MPa, making it a solid choice for light automation tasks where copper alloys are banned, such as in ammonia lines or certain battery plants. The leading 'B52-' prefix indicates this special build; please confirm the exact material substitutions with us before ordering.
This cylinder uses the ISO 6432 mounting interface for 25mm bores, so it drops into standard mini-cylinder brackets and clevises without custom adapters. The fixed TPU bumper pads soften the stroke end, though they only decelerate the piston, not hold a load. With the built-in -S magnet, you can fit CMSG, DMSG, or EMSG switches for position sensing. The 1/8" port and M10x1.25 male rod thread are standard for this bore size.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X60SCM Is Used
Ammonia Leak Test Rig
Use the copper-free build in a leak-test fixture for ammonia refrigeration lines. The 245N push force at 0.5MPa drives a sealing pad against a test port, while the stainless rod resists mild corrosion from the environment.
Battery Tab Forming Die
In a battery cell assembly line, this cylinder actuates a small forming die that bends a cathode tab. The 12.5kg vertical lift equivalent (with a 2:1 margin) is ample for the 0.2kg die, and the copper-free build suits the clean-room electronics environment.
Chemical Dosing Valve Actuator
In a chemical plant, the B52-MI25X60SCM operates a small diaphragm valve on a dosing line where copper alloys are prohibited. The 206.1N pull force at 0.5MPa retracts the valve stem reliably, and the stainless build withstands occasional washdowns.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI25X60SCM the Right Cylinder?
When sizing, consider the 20mm bore (157N push at 0.5MPa) if you need a lighter, more compact unit, or step up to the 32mm bore (402.2N push at 0.5MPa) for nearly double the force. For this 60mm stroke, side loads on the 10mm rod are minimal, but for longer strokes, always guide the load externally to prevent rod bending. The CM back cover provides a round end for flexible mounting orientation. Since this unit has the -S magnet, you can add CMSG or DMSG switches for end-of-stroke detection. Remember, a plain cylinder like this does not hold its position if air pressure is lost-the piston drifts. For a held load, use an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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.
