About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X100SCA
The B52-MBL40X100SCA is AirTAC's copper-free (copper-prohibited) version of the MBL40X100SCA, a compact double-acting aluminum mini round cylinder. With a 40 mm bore delivering 628 N push force at 0.5 MPa and a 100 mm stroke, it fits tight machine spaces where larger cylinders won't. The leading "B52-" prefix marks this as the copper-free build, intended for lines where copper and copper alloys are not permitted-such as ammonia systems and some battery, electronics, or chemical plants. The exact material substitutions should be confirmed with us.
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 long service life, while the carbon steel rod with 20 um chrome plating resists wear and corrosion. This SKU includes the CA pivot back cover, which lets the cylinder swing on a pin for arcing or angular loads, and the -S magnet for use with CMSG (reed) or DMSG/EMSG (electronic) sensor switches.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X100SCA Is Used
Ammonia Refrigeration Valve Actuation
In ammonia-based cooling skids, this copper-free cylinder actuates isolation valves without introducing copper alloys into the line. The 628 N push at 0.5 MPa handles valve stems up to 100 mm travel, while the CA pivot absorbs any angular misalignment from the linkage.
Battery Cell Tab Pressing
For lithium-ion cell tab forming, the 40 mm bore delivers a controlled 628 N force at 0.5 MPa to press tabs onto terminals. The 100 mm stroke allows clearance for cell loading, and the copper-free build avoids contamination risks in the clean, chemical-sensitive environment.
Electronics Enclosure Latch Release
In electronics cabinet assembly, this cylinder releases a spring-loaded latch on a test fixture. The compact riveted body fits behind the panel, the CA pivot handles the slight arc of the latch arm, and the -S magnet confirms retracted position via a DMSG electronic switch.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X100SCA the Right Cylinder?
At 628 N push and 528 N pull at 0.5 MPa, this 40 mm bore suits medium-light clamping, pressing, or transfer tasks. If you need more force, step up to the 50 mm bore (981 N push at 0.5 MPa); if space is tighter and less force is acceptable, the 32 mm bore (402 N push at 0.5 MPa) is the next step down. The CA pivot back cover handles angular or arcing loads, but for long strokes or heavy side loads, consider an external guide or the MBLD double-rod type to protect the 16 mm rod from bending. The fixed rubber bumper softens end-of-stroke impact, but it is not a cushion screw-for adjustable air cushioning, choose the MBLC variant. This model does not hold its position when air pressure is lost; use an external rod lock or pilot-operated check valve for load holding. Replacement match: bore 40, stroke 100, port G1/4, PT thread, CA back cover, -S magnet.
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-MBL40X100SCA FAQ
At 0.5 MPa, push force is 628 N and pull force is 528 N. At 0.7 MPa, push rises to 880 N. The theoretical maximum is 128 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa, with speed from 30-800 mm/s.
B52- marks AirTAC's copper-free (copper-prohibited) build, for lines where copper alloys are not allowed-confirm exact material substitutions with us. The base MBL has a fixed rubber bumper that softens end-of-stroke impact; it is not adjustable. For adjustable air cushioning, you would need the MBLC variant.
