Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X125SU
The AirTAC Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X125SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 125mm 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-MI16X125SU
This B52-MI16X125SU is the copper-free (copper-prohibited) version of AirTAC's MI16X125SU round-body mini cylinder, built for lines where copper and copper alloys are not permitted - for example ammonia systems and some battery, electronics and chemical plants. It remains a double-acting stainless-steel cylinder with a 16 mm bore delivering 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa.
The stainless barrel and rod give mild corrosion resistance for damp or washdown spots, while the fixed TPU bumper pads soften stroke-end impact. The 1/8" port and M6x1.0 rod thread follow the ISO 6432 mini-cylinder mounting interface, so it drops into standard mini brackets and clevises. The -S suffix means a built-in piston magnet enables CMSG, DMSG or EMSG switches. For real work at 0.5 MPa, plan for about 60 N of load rather than the full rating.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X125SU Is Used
Ammonia Handling Rig
Positions a small divert gate on an ammonia test loop where copper alloys are prohibited. The 100.5 N push at 0.5 MPa moves the lightweight flap, and the stainless rod resists the mildly corrosive atmosphere.
Battery Tab Press
Drives a small crimp tool in a lithium-cell assembly station. The 86.4 N pull at 0.5 MPa retracts the tool positively, while the copper-free build avoids contamination risk near bare cell terminals.
Electronics Panel Door
Opens a ventilation flap on a chemical-analysis cabinet. The 140.7 N push at 0.7 MPa overcomes the latch spring, and the -S magnet lets a DMSG switch confirm the flap is fully open.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X125SU the Right Cylinder?
At 16 mm bore, the MI20X... next size up gives 157.0 N push at 0.5 MPa if you need more force, while the MI12X... below gives 56.5 N push at 0.5 MPa for lighter jobs. This 125 mm stroke is within the 500 mm standard maximum for this bore, so no non-standard lead time applies. The U back cover means the rear port exits at 90 degrees, which suits tight panels where straight-in plumbing will not fit. Since this is a copper-free build, confirm the exact material substitutions with us before ordering if your line has specific chemical exposure. A plain cylinder does not hold its load when air is lost or the valve centres - the piston drifts, and the bumper pads only decelerate near stroke end. For a held load, fit an external rod lock or a pilot-operated check valve. For a 125 mm stroke, mount with LB foot or FA flange brackets to avoid side loads on the rod.
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.
Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X125SU FAQ
At 0.5 MPa the push is 100.5 N and the pull is 86.4 N. At 0.7 MPa the push rises to 140.7 N and the pull to 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa, speed 30-800 mm/s, temperature -20 to +70 C.
B52- marks AirTAC's copper-free (copper-prohibited) build of the MI16X125SU, for lines where copper alloys are not allowed - such as ammonia systems. The exact material substitutions should be confirmed with us. The -S suffix means this cylinder has a built-in piston magnet, so you can fit CMSG, DMSG or EMSG switches for position sensing.
