About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150SCAH
The AirTAC MBL40X150SCAH is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks over its 150 mm stroke. This specific SKU includes a built-in magnet for position detection and a CA pivot back cover that swings on a pin to accommodate arcing or angular loads.
Unlike tie-rod bodies, the MBL features a riveted rolling-packed barrel where the covers are crimped to the tube, ensuring a lightweight, sealed assembly that is not designed to be disassembled. The carbon steel piston rod is treated with a 20 um hard-chrome plating for superior wear and corrosion resistance. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion, while a heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150SCAH Is Used
Packaging Flap Folding
Drives the mechanical arms that fold cardboard flaps on high-speed packaging lines, utilizing the 628 N force to overcome carton stiffness while the CA pivot absorbs angular linkage movement.
Sorting Diverter Gate
Actuates a swinging diverter arm to route parcels on a conveyor belt, where the 150 mm stroke provides the necessary reach and the integrated magnet confirms gate position via a DMSG sensor.
PCB Test Fixture
Moves an array of test probes down onto printed circuit boards, relying on the compact aluminum body to fit within dense automated test equipment frames.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150SCAH the Right Cylinder?
Select this 40 mm bore when you need 628 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 32 mm bore yields 402 N; if you need more power, stepping up to the 50 mm bore provides 981 N. Because this is a double-acting cylinder, air drives both the extension and retraction strokes.
The CA clevis mount is ideal for mechanisms requiring pivot, but note that a plain MBL cannot hold its position or load if air pressure is lost, exhausted, or the valve is centred, as the rod will drift or drop. The fixed rubber bumper only softens the end-of-stroke impact and is not a lock or brake. For loads that must be held without live pressure, an external rod lock or pilot-operated check valve is required. The exact replacement match is: 40 mm bore, 150 mm stroke, G1/4 port, PT thread, CA back cover, and an -S magnet.
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 MBL40X150SCAH FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The base MBL uses a fixed rubber bumper and does not have an adjustable air cushion; if you need adjustable cushioning, look at the MBLC variant. This specific -S model includes a built-in magnet and is compatible with AirTAC CMSG (reed) and DMSG / EMSG (electronic) sensor switches.
