About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40SCA
The AirTAC MBL32X40SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It generates 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for short 40 mm stroke movements in localized automation. The riveted rolling-packed barrel keeps the overall footprint small and lightweight, though it is not designed to be disassembled like a traditional tie-rod body. A built-in magnet (-S) allows for direct mounting of AirTAC CMSG, DMSG, or EMSG sensor switches to confirm rod position.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, rather than a rigid flat-end mount. The piston utilizes a heterogeneous two-way seal that retains grease for long service life, while the carbon steel rod features 20 µm hard-chrome plating for wear and corrosion resistance. As a base MBL model, end-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40SCA Is Used
PCB Component Placement
Provides 402 N of precise push force at 0.5 MPa to seat electronic connectors onto printed circuit boards within a dense pick-and-place machine.
Packaging Flap Folding
The CA pivot back cover allows the cylinder to swing naturally while folding cardboard carton flaps on a curved conveyor path without binding.
Lab Sample Routing
Utilizes the built-in magnet and a DMSG solid-state switch to confirm the 40 mm stroke position when diverting test tube racks between analysis stations.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X40SCA the Right Cylinder?
If your application requires less force, the MBL25X40SCA offers 245 N of push force at 0.5 MPa; stepping up to the MBL40X40SCA yields 628 N. For higher cycling speeds or heavier moving masses on this 32 mm bore, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion. If you need a push-only or pull-only function without continuous air supply, the MSBL or MTBL single-acting variants cover the 20-40 mm bore range. This SKU uses a G1/8 port, M10x1.25 rod-end thread, PT thread form, and a CA pivot back cover. Note that a plain MBL does not hold its load when air pressure is lost or exhausted; the rod will drift. Use an external pilot-operated check valve or rod lock if position holding is critical.
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 MBL32X40SCA FAQ
At 0.5 MPa, the 32 mm bore provides 402 N push force and 346 N pull force. At 0.7 MPa, push force increases to 563 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL32X40SCA uses a fixed rubber bumper to soften end-of-stroke impact and does not have an adjustable cushion screw. If your application requires adjustable air cushioning for heavier loads, you must switch to the MBLC variant.
