Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X60SU
The AirTAC Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X60SU is a genuine double acting round-body mini air cylinder with a Ø20mm 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-MI20X60SU
This B52-MI20X60SU is the copper-free (copper-prohibited) version of AirTAC's MI20X60SU, built for lines where copper and copper alloys are not permitted-such as ammonia systems and some battery, electronics, and chemical plants. It remains a double-acting, round-body stainless-steel mini cylinder with a riveted construction that resists mild corrosion and washdown, making it a practical choice for damp or food-adjacent areas.
With a 20 mm bore, it delivers 157 N of push force at 0.5 MPa, which translates to a safe working load of about 94 N for real applications-roughly 60% of the rated figure. The built-in -S magnet enables CMSG, DMSG, or EMSG switches for position sensing, and the 1/8" port (PT thread, G optional) matches the ISO 6432 mounting interface for standard mini brackets. For the copper-free specifics, confirm the exact material substitutions with us, as they are not detailed here.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X60SU Is Used
Ammonia Leak Detection Rig
In a chemical plant's ammonia detection test stand, this copper-free cylinder actuates a sampling valve, with its 157 N push at 0.5 MPa handling the mechanism without risk of copper corrosion.
Battery Cell Tab Forming
For a battery assembly line, the B52-MI20X60SU presses thin tabs into place, where the copper-free build prevents contamination and the 131.9 N pull force retracts the tool cleanly.
Electronics Tray Ejector
On an electronics packaging station, this cylinder pushes finished trays off a conveyor, using its 94 N safe working load to move parts without stalling, while the stainless body shrugs off occasional washdowns.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X60SU the Right Cylinder?
When sizing, consider the next bore down, the 16 mm MI, which produces 100.5 N push at 0.5 MPa-useful if your load is lighter and space is tighter. The next step up is the 25 mm bore with 245.3 N push, which suits heavier tasks but adds bulk. This 60 mm stroke version is compact, but remember that a plain cylinder does not hold its load when air is lost or the valve is centred-the piston drifts, and the fixed TPU bumper pads only decelerate the stroke end, not act as a lock. For a held load, pair it with an external rod lock or a pilot-operated check valve. The U 90-degree back cover allows flexible port orientation, and with the -S magnet, you can add CMSG, DMSG, or EMSG switches for reliable sensing.
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-MI20X60SU FAQ
At 0.5 MPa, the push force is 157 N and the pull is 131.9 N. At 0.7 MPa, push increases to 219.8 N and pull to 184.7 N. The theoretical maximum force at 1.0 MPa is 32 kgf. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
B52- is AirTAC's copper-free (copper-prohibited) build of the MI20X60SU, intended for lines where copper alloys are banned, like ammonia systems. The exact material substitutions should be confirmed with us. This model has the -S magnet, so it works with CMSG, DMSG, or EMSG switches. The 1/8" port and M8x1.25 rod thread are standard for the 20 mm bore.
