About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X80SU
The B52-MBL32X80SU is AirTAC's copper-free (copper-prohibited) version of the compact MBL32X80SU mini round cylinder. The leading "B52-" prefix marks this build for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery, electronics, and chemical plants. While the exact material substitutions are not listed in our data, you can confirm the specific copper-free components with us before ordering.
This double-acting cylinder delivers 402 N of push force and 346 N of pull force at 0.5 MPa, with a maximum theoretical output of 82 kgf at 1.0 MPa. The 80 mm stroke suits short-travel indexing and positioning tasks. Its riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way piston seal retains grease for extended maintenance intervals. The carbon-steel rod with 20 um chrome plating resists wear and corrosion in daily service.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X80SU Is Used
Ammonia Refrigeration Valve Actuation
In ammonia-based industrial refrigeration skids, this copper-free cylinder actuates shut-off valve stems in a 80 mm stroke range. The 402 N push at 0.5 MPa overcomes valve spring resistance, while the copper-free build prevents galvanic corrosion in ammonia atmospheres.
Battery Cell Tab Positioning
On a lithium-ion cell assembly line, this cylinder advances a tab-positioning finger by 80 mm. The 346 N pull force retracts the finger cleanly between cycles, and the -S magnet lets a DMSG electronic sensor confirm the finger is home before the next weld step.
Pharma Vial Tray Indexing
In a sterile vial-filling isolator, this compact cylinder indexes a tray one station forward with an 80 mm stroke. The riveted aluminum body resists washdown chemicals better than painted steel, and the 563 N push at 0.7 MPa handles a full tray without stalling.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X80SU the Right Cylinder?
At 32 mm bore, this cylinder sits between the smaller 25 mm bore (245 N push at 0.5 MPa) and the larger 40 mm bore (628 N push at 0.5 MPa). If your application needs roughly 60% more force, step up to the MBL40X80; if you need a more compact package with about 40% less force, the MBL25X80 is the lighter option. The 80 mm stroke is a standard length, so no special-order lead time applies.
The fixed rubber bumper softens end-of-stroke impact but does not hold a load if air pressure is lost. For loads that must stay in position when the valve centers or air exhausts, add an external rod lock or a pilot-operated check valve. This SKU includes the -S magnet, so you can fit a CMSG reed switch or a DMSG/EMSG electronic sensor to detect rod position. The U flat-end back cover provides a rigid, fixed mounting surface. Port is G1/8 with PT thread form; rod-end thread is M10x1.25.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X80SU FAQ
At 0.5 MPa, push force is 402 N and pull force is 346 N. At 0.7 MPa, push force rises to 563 N. The maximum theoretical force at 1.0 MPa is 82 kgf. Operating pressure range is 0.15-1.0 MPa.
B52- marks AirTAC's copper-free (copper-prohibited) build of the MBL32X80SU, intended for lines where copper alloys are banned - for example ammonia systems. The exact substituted materials should be confirmed with us. The cylinder has a fixed rubber bumper at end-of-stroke, not an adjustable air cushion. It softens impact but does not lock the rod. The -S magnet works with CMSG (reed) or DMSG/EMSG (electronic) sensor switches.
