Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X250SCA
The AirTAC Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X250SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 250mm 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-MI20X250SCA
With a 250 mm stroke and a 20 mm bore, this round-body mini cylinder delivers 157 N of push force at 0.5 MPa, rising to 219.8 N at 0.7 MPa. The B52- prefix marks AirTAC's copper-free (copper-prohibited) build of the MI20X250SCA, tailored for lines where copper alloys are not permitted, such as ammonia systems or certain battery and chemical plants. The exact material substitutions should be confirmed with us.
The stainless-steel barrel and piston rod resist mild corrosion and washdown, making it a practical choice in damp or food-adjacent environments. Its ISO 6432 mounting interface means it drops into standard mini-cylinder brackets and clevises, simplifying spares and design. A built-in magnet (-S) enables CMSG, DMSG, or EMSG sensors for position sensing, and the fixed TPU bumper pads soften stroke-end impacts.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X250SCA Is Used
Ammonia Handling Equipment
In ammonia-based cooling or processing lines, the copper-free B52 build prevents corrosion and contamination. The 157 N push at 0.5 MPa can actuate small valves or dampers in a controlled environment.
Battery Assembly Jigs
For battery cell stacking fixtures, the 250 mm stroke provides ample travel for clamping or positioning. The stainless build resists electrolyte splash, and the -S magnet allows precise sensor feedback for cycle timing.
Food Packaging Pusher
In a washdown food packaging line, the stainless barrel and rod handle mild cleaning agents. The 131.9 N pull force at 0.5 MPa can retract a light guard or divert small cartons on a conveyor.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI20X250SCA the Right Cylinder?
This B52-MI20X250SCA sits between the smaller 16 (100.5 N push at 0.5 MPa) and the larger 25 (245.3 N push at 0.5 MPa). If your application needs more force, step up to the 25; if space is tight, the 16 offers a more compact option. For a 250 mm stroke, consider side-loading: the 20 rod is 8 mm, so use a guide or support for heavy lateral loads. The CA back cover provides a pivot/clevis mounting point. Note that this cylinder does not hold its position when air 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.
