About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400-CA
The AirTAC MBL32X400-CA 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 over a 400 mm stroke. The riveted rolling-packed barrel crimps the front and back covers directly to the tube, yielding a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The carbon-steel piston rod features a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400-CA Is Used
Pallet Transfer Diverter
Uses the 402 N push force at 0.5 MPa to deflect flat workpieces on a packaging conveyor, with the CA pivot absorbing the slight angular misalignment during the 400 mm extension.
Textile Loom Tensioner
Maintains dynamic tension on yarn guides across a 400 mm stroke, where the lightweight riveted aluminum body minimizes moving mass on high-speed loom carriages.
Bin Drawer Actuation
Extends 400 mm to open deep automated storage drawers, leveraging the compact 32 mm footprint to fit within narrow vertical pitch clearances.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400-CA the Right Cylinder?
Selecting this 32 mm bore makes sense when you need more power than the 25 mm size (245 N push at 0.5 MPa) but lack the physical space for a 40 mm cylinder (628 N push at 0.5 MPa). The CA clevis mount is essential for mechanisms requiring angular rod movement during the 400 mm travel. If your cycle times generate destructive end-of-stroke impacts, step up to the MBLC variant for its adjustable air cushion, as the base MBL relies solely on a fixed rubber bumper.
At 400 mm of stroke, the Ø12 mm rod has low side-load tolerance and is highly susceptible to bending under lateral forces; an external guide rail is strongly recommended to prevent premature seal failure. Note that a plain MBL does not hold its position if air pressure is lost or the valve is centered, as the rubber bumper only softens impact and acts as neither a lock nor a brake. For exact replacement, match the 32 mm bore, 400 mm stroke, G1/8 port, PT thread, and CA pivot back cover.
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 MBL32X400-CA FAQ
At 0.5 MPa, this double-acting cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No. Because this specific SKU lacks the -S magnet suffix, you cannot mount a CMSG, DMSG, or EMSG sensor switch to detect rod position. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; you must upgrade to the MBLC variant to get adjustable air cushioning.
