About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125U
The AirTAC MBL32X125U is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 32mm bore and a 125mm stroke, generating 402N of push force and 346N of pull force at 0.5 MPa. The U suffix indicates a flat-end back cover for rigid rear mounting. Because this specific SKU lacks the -S magnet suffix, it cannot accept an electronic or reed position sensor.
Unlike tie-rod bodies, the MBL barrel is riveted and rolling-packed, permanently crimping the front and rear covers to the tube for an exceptionally light, compact footprint. Internal longevity relies on a heterogeneous two-way piston seal that retains grease, while the 12mm carbon-steel piston rod features 20µm hard-chrome plating to resist wear and corrosion. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125U Is Used
PCB Router Z-Axis Gate
Actuates a pneumatic dust-extraction gate on a PCB depaneling router, using its 402N push force to open the shroud exactly 125mm during spindle routing.
Carton Flap Folder
Folds secondary corrugated carton flaps on a compact packaging line, where the rigid U flat-end rear mount bolts directly to the machine frame in a tight clearance zone.
Connector Pick-and-Place
Drives a 125mm vertical pick-and-place stroke for transferring electronic connectors between testing trays, relying on the lightweight riveted aluminum body to minimize Z-axis mass.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125U the Right Cylinder?
This 32mm bore yields 402N (push) at 0.5 MPa. If your assembly requires less force, step down to the 25mm bore offering 245N; if you need more clamping power, step up to the 40mm bore providing 628N. The base MBL uses a fixed rubber bumper, so for faster cycling with heavier loads, select the MBLC variant for its adjustable air cushion. Keep in mind the MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. Use an external pilot-operated check valve if position retention is required.
With a 125mm stroke on a 12mm rod, this cylinder has moderate side-load tolerance. For longer unsupported moves, an external guide rail is recommended to prevent rod-bearing bending. Direct drop-in replacements must match the 32mm bore, 125mm stroke, G1/8 port, PT thread form, U flat-end back cover, and no-magnet configuration.
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 MBL32X125U FAQ
At 0.5 MPa it provides 402N push and 346N pull force, increasing to 563N push at 0.7 MPa, with a maximum theoretical force of 82 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, runs at 30-800 mm/s, and uses a G1/8 port.
No. Because the model code lacks the -S suffix, this specific SKU has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. If position detection is required, order the MBL32X125SU variant.
