About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X120SU
The AirTAC MBL32X120SU is a compact 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 120 mm stroke routing or gating tasks. The riveted rolling-packed barrel crimps the covers directly to the tube, yielding a lighter footprint than tie-rod builds but rendering the body non-serviceable.
This SU configuration includes a U flat-end back cover for rigid fixed mounting and a built-in magnet (-S) for non-contact position sensing. You can mount CMSG reed or DMSG and EMSG solid-state switches along the body to detect the rod at any point. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X120SU Is Used
Package Diverting
Actuates a routing flap on a packaging conveyor, using the 120 mm stroke to shift small cartons between lanes with 402 N of push force.
Small Part Ejection
Pushes stamped metal small parts out of a press die area, relying on the U flat-end back cover for rigid, square mounting against the machine frame.
PCB Test Fixture
Moves an electronic test probe head into position over a circuit board, using the built-in magnet and a DMSG solid-state switch to confirm test contact.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X120SU the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push at 0.5 MPa); if you need more clamping power, step up to the 40 mm bore (628 N push at 0.5 MPa). Choose the MBLC variant if your 120 mm move requires adjustable air cushioning to soften heavy end-of-stroke impacts, as this base MBL relies on a fixed rubber bumper. For single-acting push or pull needs, consider the MSBL or MTBL series. This SKU uses a G1/8 port, PT thread form, M10x1.25 rod-end thread, U flat-end back cover, and a built-in magnet.
Because the 120 mm stroke extends the 12 mm rod significantly, it is highly susceptible to side-load bending. Use an external guide rail or a pivot knuckle to prevent rod-bearing damage. Additionally, a plain MBL does not hold its load if air pressure drops or the valve is centered—the rod will drift. Install an external rod lock or pilot-operated check valve if gravity or load holding is required.
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 MBL32X120SU FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted like the MBLC air cushion variant. Additionally, the bumper is not a brake; the cylinder cannot hold a load or maintain position if air pressure is lost or the valve is centered. Use an external rod lock for fail-safe holding.
