About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SU
The AirTAC MBL32X300SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 32mm bore and a 300mm stroke, generating 402N of push force and 346N of pull force at 0.5 MPa. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod cylinder. This specific SKU includes a U flat-end back cover for rigid mounting and a built-in -S magnet for position detection.
Internal mechanics rely on a heterogeneous two-way piston seal that retains grease for long service life, paired with a carbon steel piston rod plated with 20 μm hard chrome to resist wear and corrosion. The -S magnet enables direct mounting of AirTAC CMSG reed switches or DMSG and EMSG solid-state sensors along the body. End-of-stroke energy is absorbed by a fixed rubber bumper, which softens impact but is not an adjustable cushion. If your process demands speed or weight tuning at the stroke ends, step up to the MBLC variant for its adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SU Is Used
PCB Conveyor Diversion
Pushes lightweight routing gates on a PCB conveyor system where 402N of push force at 0.5 MPa easily overcomes friction, while the U flat-end rear cover stays rigidly bolted to the frame.
Test Handler Escapement
Drives a 300mm linear escapement to stage IC packages in a semiconductor test handler, using the -S magnet with a DMSG solid-state sensor to confirm full extend position.
Carton Flap Folder
Folds minor flaps on a compact carton erecting line where the 32mm bore fits inside the narrow machine envelope, and the fixed rubber bumper absorbs the 300mm stroke impact.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SU the Right Cylinder?
This 32mm bore provides 402N of push force at 0.5 MPa. If you need less force to move a lighter payload, step down to the 25mm bore which offers 245N of push force. If your application requires moving a heavier load, step up to the 40mm bore which provides 628N. Because this is a 300mm stroke, the 12mm rod has a long unsupported span; under side loads the rod bearing can bend. You must use an external guide, a CA pivot back cover, or switch to the MBLD double-rod anti-rotation type to prevent premature wear. This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors, a U flat-end rear, and a PT port thread form at G1/8.
The fixed rubber bumper only softens end-of-stroke impact and is not a lock. If air pressure drops or the valve is centered, the rod will drift and the load will drop. To hold a suspended load safely without live pressure, install an external rod lock or a pilot-operated check valve in the air circuit.

- ✓ 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 MBL Aluminum Alloy Mini Cylinder MBL32X300SU FAQ
At 0.5 MPa this 32mm bore cylinder outputs 402N push and 346N pull force. At 0.7 MPa the push force is 563N, and the maximum theoretical force is 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL has a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. To regulate end-of-stroke speeds for heavier moving loads, you must switch to the MBLC variant which features an adjustable air cushion.
