About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X75SCA
The B52-MBL32X75SCA is AirTAC's copper-free (copper-prohibited) version of the MBL32X75SCA, a compact double-acting aluminum mini round cylinder. The leading "B52-" prefix designates a build where copper and copper alloys are not permitted, making it suitable for lines such as ammonia systems and certain battery, electronics, and chemical plants. Exact material substitutions should be confirmed with us for your specific application.
With a 32mm bore, this cylinder delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The 75mm stroke suits short-travel indexing and clamping tasks in tight machine spaces. The riveted rolling-packed aluminum barrel keeps the body light and compact, though it is not designed for disassembly like a tie-rod cylinder. The heterogeneous two-way piston seal retains grease for extended maintenance intervals, while the 12mm carbon-steel rod with 20um chrome plating resists wear and corrosion.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X75SCA Is Used
Battery Cell Tab Forming
In battery production lines where copper contamination is prohibited, this 32mm bore cylinder delivers 402 N at 0.5 MPa to form thin metal tabs on prismatic cells. The 75mm stroke provides adequate travel for the pressing motion while the compact body fits between conveyor rails.
Pharmaceutical Vial Indexing
On a vial filling line, the B52-MBL32X75SCA advances a stop gate that positions vials under the filling nozzle. The CA pivot back cover lets the cylinder swing slightly to absorb misalignment, while the copper-free build prevents any risk of metal contamination in the sterile environment.
Ammonia Refrigeration Valve Actuation
In an industrial ammonia refrigeration plant, this copper-free cylinder actuates a small shut-off valve. The 563 N push force at 0.7 MPa is sufficient to move the valve stem, and the copper-prohibited construction avoids corrosion that copper alloys would suffer in ammonia service.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL32X75SCA the Right Cylinder?
For applications requiring more force, step up to the 40mm bore MBL40, which provides 628 N push at 0.5 MPa. If you need less force and a smaller footprint, step down to the 25mm bore MBL25, offering 245 N push at 0.5 MPa. The CA pivot back cover allows this cylinder to swing on a pin, accommodating arcing or angular loads; pair it with an SDB pivot bracket or a clevis for best results.
This model includes the -S magnet, so it works with AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensor switches for rod position detection. The fixed rubber bumper softens end-of-stroke impact but is not an adjustable air cushion-that is the MBLC variant. Note that this cylinder does not hold its position when air pressure is lost; for load holding, use an external rod lock or pilot-operated check valve. The port is G1/8 with PT thread form, and the 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-MBL32X75SCA FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, push force rises to 563 N. The theoretical maximum force is 82 kgf at 1.0 MPa. These figures apply to the standard MBL32X75SCA and are shared by this copper-free B52- version.
B52- marks AirTAC's copper-free (copper-prohibited) build of the MBL32X75SCA, intended for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery and chemical plants. The exact material substitutions should be confirmed with us. Regarding cushioning, this base MBL model has a fixed rubber bumper that softens end-of-stroke impact-it is not an adjustable air cushion. For adjustable cushioning, consider the MBLC variant.
