About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40CA
The AirTAC MBL32X40CA is a double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 32mm bore and 40mm stroke, it generates 402N of push force and 346N of pull force at 0.5 MPa. The riveted rolling-packed barrel crimps the covers directly to the tube, ensuring a lightweight, compact footprint that is not designed to be disassembled like a tie-rod cylinder.
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. It uses a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Because this model lacks the -S suffix, it cannot be fitted with a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40CA Is Used
Textile Loom Tensioning
Uses the CA pivot back cover to swing smoothly with the weaving mechanism, applying 402N of force to maintain thread tension in compact loom frames.
Package Diverter Arm
Pivots a sorting flap on a packaging conveyor where 346N of pull force retracts the arm to let small cartons pass in a tight transfer zone.
PCB Router Gate
Actuates a routing gate on a circuit board assembly line, utilizing the 40mm stroke and fixed rubber bumper to stop moving pallets without harsh impact.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40CA the Right Cylinder?
At 0.5 MPa, this 32mm bore provides 402N push and 346N pull force. If you need less force, step down to the 25mm bore (245N push); if your application requires more, step up to the 40mm bore (628N push). Choose the MBLC variant if your cycle times demand an adjustable air cushion rather than the standard fixed rubber bumper. If you need spring-return actuation, consider the MSBL or MTBL single-acting series.
The CA pivot back cover is ideal for angular loads, but note that a plain MBL does not hold its position or load when air pressure is lost or the valve is centered—the rod will drift. For load-holding safety, use an external rod lock or a pilot-operated check valve. Replacement parts must match the 32mm bore, 40mm stroke, G1/8 port, PT thread, and CA clevis configuration.
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 MBL32X40CA FAQ
At 0.5 MPa, the 32mm bore pushes with 402N and pulls with 346N. At 0.7 MPa, push force reaches 563N, with a maximum theoretical force of 82 kgf at 1.0 MPa. The cylinder does not hold its position if air pressure drops; you need an external rod lock for load holding.
No, the MBL32X40CA uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion (which requires the MBLC variant). Additionally, because it lacks the -S magnet suffix, you cannot mount CMSG, DMSG, or EMSG electronic or reed sensor switches to detect rod position.
