About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20CA
The AirTAC MBL32X20CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 32mm bore and 20mm stroke, it generates 402N of push force and 346N of pull force at 0.5 MPa. This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during the short 20mm travel. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.
Built with a riveted rolling-packed aluminum barrel, the front and back covers are crimped directly to the tube for an ultra-light footprint, though this means it is not designed to be disassembled like a traditional tie-rod body. The carbon-steel piston rod features a 20 um hard-chrome plating for high wear and corrosion resistance. Instead of an adjustable cushion, the base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20CA Is Used
PCB Depaneling Router
Drives a short 20mm arcing cutter motion on an automated PCB depaneling machine, using the CA pivot to absorb slight lateral cutter deflection while applying 402N of push force at 0.5 MPa.
Lab Sample Tray Indexer
Pivots a small diagnostic sample tray in a compact analyzer, where the 32mm bore provides 346N of pull force to retract the mechanism and the clevis mount tolerates angular misalignment.
Carton Flap Folder
Folds lightweight cardboard flaps on a packaging line, swinging into position via the CA clevis while the short 20mm stroke keeps the overall mechanism footprint minimal.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20CA the Right Cylinder?
For a 32mm bore, stepping down to the 25mm bore yields 245N push force at 0.5 MPa, while stepping up to the 40mm bore provides 628N. Choose the 40mm if your 32mm stalls under peak load, or drop to 25mm for lighter, faster cycling. If your application requires end-position speed regulation for heavier masses, step up to the MBLC variant which adds an adjustable air cushion. For single-acting push or pull needs, consider the MSBL or MTBL series.
This SKU uses a G1/8 port with a default PT tapered thread, an Ø12mm rod with an M10x1.25 rod-end thread, and a CA pivot back cover. A plain MBL does not hold its load when air pressure is lost or exhausted; the rod will drift. The fixed rubber bumper only softens the impact at the end of stroke and is not a locking brake. If you need to maintain vertical position during a pressure drop, add an external pilot-operated check valve.
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 MBL32X20CA FAQ
At 0.5 MPa, the push force is 402N and the pull force is 346N. At 0.7 MPa, the push force increases to 563N. The maximum theoretical force is 82 kgf when operating at the 1.0 MPa pressure limit.
No. The base MBL32X20CA uses a fixed rubber bumper to absorb end-of-stroke impact rather than an adjustable air cushion (which requires the MBLC variant). Additionally, because this model lacks the -S suffix for a built-in magnet, it cannot be fitted with any CMSG, DMSG, or EMSG electronic or reed position sensor.
