About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350SU
The AirTAC MBL32X350SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit provides a 350 mm stroke while operating at speeds between 30-800 mm/s. The integrated -S magnet enables precise rod-position detection using AirTAC CMSG, DMSG, or EMSG sensor switches.
Unlike tie-rod bodies, this cylinder uses a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, creating a lightweight, permanently sealed assembly not designed for field disassembly. The Ø12 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350SU Is Used
PCB Router Ejection
Pushes routed printed circuit boards out of a machining fixture using 402 N of force, with the -S magnet confirming full extension before the conveyor advances.
Packaging Flap Folder
Actuates a 350 mm arm to fold corrugated carton flaps on a packaging line, fitting into narrow frame gaps where larger cylinders cannot mount.
Lab Sample Tray Transfer
Indexes diagnostic sample trays between testing modules, relying on the DMSG electronic sensor to signal the precise handoff position to the PLC.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350SU the Right Cylinder?
For lower force needs, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while moving up to the 40 mm bore provides 628 N. Because this SKU lacks an adjustable cushion, relying instead on a fixed rubber bumper, heavier or faster loads should use the MBLC variant. Note that a plain MBL cannot hold a load if air pressure drops; use an external rod lock or pilot-operated check valve for fail-safe positioning.
With a 350 mm stroke on a Ø12 mm rod, side-load tolerance is low. An external guide rail is strongly recommended to prevent rod-bearing bending. Replacement specifications: 32 mm bore, 350 mm stroke, G1/8 port, PT thread, U flat-end back cover, and a built-in 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 MBL32X350SU FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa the push force is 563 N, and the theoretical maximum force is 82 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts. If your application requires adjustable air cushioning to slow heavier loads, you must step up to the MBLC variant.
