About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X30SU
The AirTAC MBL32X30SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 402 N of push force at 0.5 MPa, this 32 mm bore, 30 mm stroke unit is built for fast, short linear movements. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This SU configuration features a U flat-end back cover for rigid mounting and includes a built-in magnet (-S) for non-contact position detection. It is wired for AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches. The carbon-steel piston rod is hard-chrome plated by 20 um to resist wear, while the heterogeneous two-way piston seal retains grease for a long, maintenance-free service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X30SU Is Used
PCB Router Z-Axis
Drives the vertical plunge of a PCB depaneling router, using the 30 mm stroke and 402 N force to cleanly cut substrate without stressing the board.
Carton Flap Folder
Actuates a mechanical flap-folding arm on a small packaging line, relying on the rigid U flat-end back cover to maintain alignment during the fold.
Connector Insertion Press
Pushes IC sockets into plated through-holes on an assembly fixture, using the -S magnet and a DMSG sensor to verify the 30 mm insertion depth is reached.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X30SU the Right Cylinder?
At 0.5 MPa this 32 mm bore provides 402 N push and 346 N pull force. If you need less force, step down to the 25 mm bore (245 N push); if your mechanism requires more thrust, step up to the 40 mm bore (628 N push). The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts—if your payload is heavy and requires a regulated stop, choose the MBLC variant for its adjustable air cushion.
Because this is a double-acting cylinder, it will not hold its load if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve or a rod lock for fail-safe load holding. Replacement parts must match the 32 mm bore, 30 mm stroke, G1/8 port, PT thread, U flat-end cover, and the -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 MBL32X30SU FAQ
At 0.5 MPa the push force is 402 N and the pull force is 346 N. At 0.7 MPa the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
No, the base MBL32X30SU uses a fixed rubber bumper to absorb end-of-stroke impact. If you need adjustable pneumatic cushioning for heavier loads, select the MBLC variant.
