About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175SU
The AirTAC MBL32X175SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 0.5 MPa it provides 402 N of push force and 346 N of pull force, making this 175 mm stroke variant well suited for mid-range positioning tasks. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight footprint that is not designed to be disassembled like a tie-rod body.
This SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed or DMSG and EMSG solid-state switches. It features a U flat-end back cover for rigid fixed mounting, while the carbon-steel piston rod is plated with 20 um of hard chrome to resist wear and corrosion. The bore uses a G1/8 port and a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175SU Is Used
Pouch Sealing Diverter
Actuates a routing flap on a packaging conveyor to divert filled pouches into a secondary sealing lane using 402 N of push force at 0.5 MPa.
PCB Test Fixture
Drives a 175 mm stroke to lower an electronic test probe assembly over printed circuit boards, using the built-in magnet to confirm full extension.
Carton Flap Folder
Deploys a mechanical arm at 346 N pull force to tuck minor flaps on small corrugated cartons before tape application in a compact packing cell.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175SU the Right Cylinder?
Select this 32 mm bore when an application requires more power than the 25 mm bore (245 N push at 0.5 MPa) but lacks the physical space for a 40 mm bore (628 N push at 0.5 MPa). The 175 mm stroke provides ample extension for packaging or sorting tasks. If your system needs to absorb heavy end-of-stroke kinetic energy, step up to the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
Because this model lacks a locking mechanism, the rod will drift or drop if air pressure is lost or the valve is centered; use an external pilot-operated check valve if the load must be held. At 175 mm of extension, the Ø12 mm rod has moderate side-load tolerance; for offset loads, consider an external guide rail or the MBLD double-rod anti-rotation type. This exact replacement requires a 32 mm bore, 175 mm stroke, G1/8 PT port, U flat-end back 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 MBL32X175SU FAQ
This double-acting cylinder delivers 402 N push and 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. It operates at speeds between 30 and 800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (you would need the MBLC variant for that). Additionally, it does not hold position if air pressure drops; a separate rod lock or pilot check valve is required for load holding.
