About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SU
The AirTAC MBL32X75SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 402 N of push force and 346 N of pull force at 0.5 MPa, this 32 mm bore, 75 mm stroke unit is built for light-duty positioning and ejection. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a featherweight body that is not designed to be disassembled or rebuilt like a traditional tie-rod cylinder.
This specific SKU includes the -S built-in magnet for non-contact position detection using CMSG reed or DMSG and EMSG solid-state sensor switches. It features the U flat-end back cover for rigid fixed mounting and a carbon-steel piston rod with a 20 um hard-chrome plating to resist wear and corrosion. The internal heterogeneous two-way piston seal retains grease, ensuring smooth friction-free travel across its 30-800 mm/s operating speed range.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SU Is Used
PCB Depaneling Ejector
Uses the 402 N push force at 0.5 MPa to safely eject freshly routed printed circuit boards from a routing fixture without damaging delicate surface-mount components.
Connector Insertion Press
Provides the precise 75 mm stroke and 346 N pull force needed to seat ribbon cable connectors into housing blocks during consumer electronics assembly.
Small Carton Flap Folder
Drives a compact mechanical arm to fold minor flaps on small pharmaceutical cartons where the lightweight riveted aluminum body minimizes moving mass.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SU the Right Cylinder?
Select this 32 mm bore when an application requires roughly 400 N of thrust at 0.5 MPa. If your fixture needs less force, step down to the 25 mm bore offering 245 N push force; if you need to move heavier payloads, step up to the 40 mm bore providing 628 N push force. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts, so choose the MBLC variant if your cycle rates demand adjustable air cushioning to decelerate heavier moving masses.
Because this is a double-acting cylinder, it cannot hold its position or load if air pressure is lost or the valve is centered; the rod will drift. An external pilot-operated check valve or rod lock is required for fail-safe load holding. For exact replacement matching, verify the 75 mm stroke, G1/8 port size, PT tapered thread form, U flat-end back cover, and the -S magnet requirement before ordering.
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 MBL32X75SU FAQ
At 0.5 MPa this cylinder outputs 402 N push and 346 N pull force. At 0.7 MPa the push force increases to 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL32X75SU uses a fixed rubber bumper to absorb end-of-stroke impact and cannot be adjusted. If your application requires tunable deceleration for heavier loads, you must upgrade to the MBLC variant which features an adjustable air cushion.
