About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X150SU
The AirTAC MBL32X150SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 402 N of push force and 346 N of pull force, making it well-suited for mid-range 150 mm actuation tasks. The riveted rolling-packed barrel design keeps the body light and small, though it is not built to be disassembled like a tie-rod cylinder. This U flat-end configuration provides a rigid rear mounting surface for straightforward fixed installations.
This specific SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed or DMSG/EMSG electronic sensor switches. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. To ensure long service life, the Ø12 mm carbon-steel piston rod features 20 µm hard-chrome plating, and a heterogeneous two-way piston seal continually retains grease during operation.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X150SU Is Used
PCB Depaneling Router
Provides 402 N of push force at 0.5 MPa to actuate the routing spindle or fixture on an automated PCB depaneling machine, fitting neatly within the tight electronics assembly cell.
Packaging Flap Folder
Drives a mechanical arm to fold minor carton flaps on a continuous flow packaging conveyor, utilizing the 150 mm stroke to clear the product path during retraction.
Lab Tube Capper
Applies precise downward force to press and seal caps on centrifuge tubes in a laboratory automation line, with the -S magnet confirming the cap is fully driven home.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X150SU the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push @0.5 MPa); if your application demands more power, step up to the 40 mm bore (628 N push @0.5 MPa). For higher kinetic energy moves, the MBLC variant offers an adjustable air cushion instead of the standard fixed rubber bumper. Because this is a 150 mm stroke, the unsupported Ø12 mm rod is susceptible to bending under side loads—use an external guide or switch to the MBLD double-rod type to prevent premature wear. Note that the fixed rubber bumper only softens impact and does not lock the rod; this cylinder cannot hold a load if air pressure is lost or the valve is centered. Replacement match: 32 mm bore, 150 mm stroke, G1/8 port, PT thread, U flat-end back cover, no mounting accessory, magnet included.
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 MBL32X150SU FAQ
This 32 mm bore cylinder uses a Ø12 mm carbon-steel rod with an M10x1.25 rod-end thread and a G1/8 port. It delivers 402 N push / 346 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impacts and cannot be adjusted. If your application requires adjustable air cushioning for heavier or faster moving loads, you should select the MBLC variant.
