About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X175SCA
The B52-MBL40X175SCA is the copper-free (copper-prohibited) version of AirTAC's MBL40X175SCA, a compact double-acting aluminum mini round cylinder. With a 40 mm bore, it delivers 628 N of push force at 0.5 MPa and 880 N at 0.7 MPa, making it a strong yet lightweight option for tight machine spaces. The 175 mm stroke suits medium-travel applications where a larger cylinder simply won't fit.
The "B52-" prefix marks AirTAC's copper-free build, designed for lines where copper and copper alloys are not permitted, such as ammonia systems and certain battery, electronics, or chemical plants. This model includes the CA pivot back cover, which swings on a pin for arcing or angular loads, and the -S magnet for position sensing with CMSG (reed) or DMSG/EMSG (electronic) switches. The riveted rolling-packed barrel keeps it light and compact, though it is not designed for disassembly like a tie-rod cylinder.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X175SCA Is Used
Battery Cell Crimping
In battery cell assembly, the B52-MBL40X175SCA's 628 N push at 0.5 MPa provides controlled force for crimping tabs. The copper-free build prevents contamination in sensitive electronics environments, and the CA pivot allows alignment with angled cell casings.
Pharmaceutical Vial Capping
For capping small vials in a clean pharmaceutical line, this 40 mm bore cylinder delivers 880 N at 0.7 MPa to seat caps firmly. The compact riveted body fits under a laminar flow hood, and the magnet allows position confirmation via a DMSG electronic switch.
Chemical Plant Valve Actuation
In ammonia or chemical processing, the copper-free B52-MBL40X175SCA actuates small control valves where copper alloys are prohibited. The 175 mm stroke provides the travel needed, while the CA pivot absorbs minor pipe misalignment without binding the rod.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X175SCA the Right Cylinder?
The B52-MBL40X175SCA sits between the MBL32 and MBL50 in force. If you need less push, the MBL32 offers 402 N at 0.5 MPa; if you need more, the MBL50 provides 981 N at 0.5 MPa. The CA pivot back cover handles angular or arcing loads, but for long unsupported strokes, consider an external guide or the MBLD double-rod type to prevent rod bending. Note that this cylinder has a fixed rubber bumper, not an adjustable cushion-for that, choose the MBLC variant. The G1/4 port with PT thread is fixed by the 40 mm bore. The -S magnet enables sensor detection; without it, no sensor can be fitted. This model does not hold its position when air pressure is lost-use an external rod lock or pilot-operated check valve if load holding is critical.
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-MBL40X175SCA FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, push force rises to 880 N. The theoretical maximum is 128 kgf at 1.0 MPa. These figures are identical to the standard MBL40X175SCA.
B52- denotes AirTAC's copper-free (copper-prohibited) build, for lines where copper and copper alloys are not allowed. The exact material substitutions should be confirmed with us. The cylinder has a fixed rubber bumper, not an adjustable air cushion-for adjustable cushioning, choose the MBLC variant.
