About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL25X100SU
The B52-MBL25X100SU is AirTAC's copper-free (copper-prohibited) build of the compact MBL25X100SU double-acting mini round cylinder. With a 25mm bore and 100mm stroke, it delivers 245N of push force at 0.5MPa, making it a robust choice for tight machine spaces where standard cylinders won't fit. The B52- prefix indicates a version designed for lines where copper and copper alloys are not permitted, such as ammonia systems and certain battery, electronics, or chemical plants. Please confirm the exact material substitutions with us, as our data does not specify them.
The riveted rolling-packed aluminum barrel keeps this cylinder light and compact, while the heterogeneous two-way piston seal retains grease for extended service life. The carbon-steel rod features 20um hard-chrome plating for wear and corrosion resistance. This model includes the -S magnet, allowing position sensing with AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensor switches. The U back cover provides a rigid, flat-end mounting surface, ideal for fixed installations.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL25X100SU Is Used
Ammonia Refrigeration Valve Actuation
In ammonia-based industrial refrigeration systems, copper is prohibited due to corrosion risks. This copper-free B52-MBL25X100SU safely actuates small control valves or dampers, delivering 245N push at 0.5MPa in tight plant rooms.
Battery Cell Manufacturing Jig
In battery production lines where copper contamination is a concern, this cylinder operates a 100mm-stroke clamping jig for cell assembly. The 206N pull force at 0.5MPa reliably retracts the fixture, while the -S magnet confirms position via a DMSG electronic switch.
Chemical Dosing Pump Guard
For chemical plants that restrict copper alloys, this MBL guards a small dosing pump access panel. Its 343N push at 0.7MPa overrides a safety interlock, and the compact riveted body fits within the equipment's minimal envelope.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL25X100SU the Right Cylinder?
For applications needing more force, step up to the 32mm bore MBL, which provides 402N push at 0.5MPa. If 245N is more than sufficient, the 20mm bore version offers 157N push at 0.5MPa, saving space and weight. This B52-MBL25X100SU has a G1/8 port with PT thread, a 10mm rod with M10x1.25 thread, and a U flat-end back cover. It is double-acting, so air both extends and retracts the rod. Remember, this cylinder has a fixed rubber bumper for end-of-stroke impact, not an adjustable cushion (that's the MBLC variant). It does not hold its position when air pressure is lost; for load holding, use an external rod lock or pilot-operated check valve. The -S magnet enables sensor mounting.

- ✓ 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-MBL25X100SU FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The theoretical maximum force is 50 kgf at 1.0 MPa. These figures are identical to the standard MBL25X100SU.
The B52- prefix designates AirTAC's copper-free (copper-prohibited) build, intended for lines where copper alloys are not allowed, such as ammonia systems. The exact material substitutions should be confirmed with us. The -S suffix means a built-in magnet is included, so you can mount an AirTAC CMSG reed switch or a DMSG/EMSG electronic switch to detect rod position.
