About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80U
The AirTAC MBL32X80U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating with a 32mm bore and 80mm stroke, it generates 402N of push force and 346N of pull force at 0.5MPa, making it well-suited for mid-range actuation tasks where footprint matters.
This specific U variant features a rigid flat-end rear cover for fixed mounting. The body utilizes a riveted rolling-packed aluminum barrel that is permanently crimped, meaning it is not designed to be disassembled or rebuilt like a tie-rod cylinder. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the 12mm carbon steel rod is protected by 20um hard-chrome plating. Note that because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80U Is Used
Pouch Transfer Gates
Diverts lightweight packaging pouches on a 24V conveyor line using 402N of push force to actuate a routing flap within a narrow 100mm machine cavity.
PCB Test Trays
Raises and lowers printed circuit board test trays with a precise 80mm stroke, relying on the rigid U flat-end mount to maintain orthogonal alignment under rapid cycling.
Lab Dispenser Capping
Secures small vial caps in automated diagnostic equipment, where the compact riveted aluminum body fits between densely packed dispensing heads without requiring ISO 15552 clearance.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80U the Right Cylinder?
When sizing this 32mm bore, stepping down to the 25mm bore reduces your push force to 245N at 0.5MPa, while stepping up to the 40mm bore increases it to 628N. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your application requires adjustable air cushioning for heavier moving masses, select the MBLC variant instead. Furthermore, this cylinder does not hold its position if air pressure is lost or the valve is centered—the rod will drift. Use an external rod lock or pilot-operated check valve if gravity or load drift is a concern. For exact replacement, match the 32mm bore, 80mm stroke, G1/8 port, PT thread, and U flat-end back cover.
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 MBL Aluminum Alloy Mini Cylinder MBL32X80U FAQ
At 0.5MPa it provides 402N push and 346N pull; at 0.7MPa push increases to 563N. The maximum theoretical force is 82kgf at 1.0MPa. The operational speed range is 30-800mm/s.
This model uses a fixed rubber bumper, not an adjustable air cushion screw (which requires the MBLC variant). Additionally, because it lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG electronic position sensors.
