About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225U
The AirTAC MBL32X225U is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for mid-range actuation over a 225 mm stroke. The U suffix denotes a rigid flat-end back cover for direct rear mounting. Because this SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike tie-rod cylinders, the MBL body uses a riveted rolling-packed barrel where the covers are crimped to the tube, yielding a lighter footprint but a non-rebuildable assembly. Internal longevity relies on a heterogeneous two-way piston seal that retains grease, paired with a carbon steel rod protected by 20 um hard-chrome plating. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225U Is Used
Package Sorter Diverter
Provides the 402 N push force needed to deflect small cardboard cartons on a 225 mm stroke at a logistics sorting hub.
PCB Router Gate
Shifts an automated routing gate for printed circuit board handling, utilizing the rigid U flat-end cover for a fixed pivot point.
Bottle Feed Discharge
Pushes empty plastic bottles into a filling line carousel, where the compact riveted barrel fits within the tight machine guarding.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225U the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 402 N push. If your application requires less force, step down to the 25 mm bore (245 N push); if you need more power, step up to the 40 mm bore (628 N push). If your cycle speed creates heavy end-loads, upgrade to the MBLC variant for an adjustable air cushion. Note that the fixed rubber bumper softens impact but does not lock the rod—unpressurized loads will drift, requiring an external pilot-operated check valve for position holding.
With a 225 mm stroke, the 12 mm rod is highly susceptible to side-load bending and premature bearing wear. To prevent rod deflection, use an external linear guide, pair the cylinder with a pivot knuckle, or switch to the MBLD double-rod cylinder for anti-rotation stability. Replacement match: 32 mm bore, 225 mm stroke, G1/8 port, PT thread, U flat-end back cover, no 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 MBL Aluminum Alloy Mini Cylinder MBL32X225U FAQ
At 0.5 MPa, push force is 402 N and pull force is 346 N. At 0.7 MPa, push increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No. The base MBL uses a fixed rubber bumper, not an adjustable air cushion (you need the MBLC variant for that). Additionally, this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG electronic or reed position sensors.
