About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X185SU
The AirTAC MBL32X185SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where larger units cannot fit. Operating at 0.5 MPa, it provides 402 N of push force and 346 N of pull force across its 185 mm stroke. This genuine AirTAC unit features a built-in magnet for position detection and a rigid U flat-end rear cover for secure fixed mounting.
Unlike tie-rod cylinders, the MBL body uses a riveted rolling-packed aluminum barrel that crimps the covers to the tube, prioritizing a light footprint over field-rebuildability. Internal longevity is driven by a heterogeneous two-way piston seal that retains grease, paired with a carbon steel rod hardened with 20 μm chrome plating to resist wear and corrosion. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion screw.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X185SU Is Used
PCB Router Z-Axis Gate
Drives a 402 N pneumatic gate that blocks dust extraction nozzles when a PCB routing spindle retracts, fitting cleanly within the 185 mm stroke envelope.
Carton Flap Folder
Actuates a 346 N pull mechanism on a packaging conveyor to tuck minor flaps before tape sealing, using the rigid U flat-end cover to absorb repeated shocks.
Connector Pick-and-Place
Provides 185 mm of vertical travel for a sensor pick-head moving electronic connectors, triggering a CMSG reed switch to confirm the exact pickup height.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X185SU the Right Cylinder?
If your application requires less force, step down to the 25 mm bore (245 N push @0.5 MPa); if you need more power, step up to the 40 mm bore (628 N push @0.5 MPa). Because this 185 mm stroke pushes a Ø12 mm rod, keep side-load tolerance in mind—long unsupported mini rods bend under lateral stress. Use an external guide or pivot bracket to protect the rod bearing. To slow heavier loads at stroke end, choose the MBLC variant for its adjustable air cushion. Note that this cylinder does not hold its load if air pressure drops; add an external rod lock or pilot-operated check valve for fail-safe positioning. Replacement match: 32 mm bore, 185 mm stroke, G1/8 port, PT thread, U flat-end back cover, with -S 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 MBL32X185SU FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa it pushes 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
No, the base MBL32X185SU uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. For adjustable air cushioning, select the MBLC variant.
