About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10SU
The AirTAC MBL40X10SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 40mm bore and 10mm stroke, it generates 628 N of push force and 528 N of pull force at 0.5 MPa. The U flat-end back cover provides a rigid, fixed mounting footprint ideal for short-stroke clamping.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensor switches, allowing precise end-of-stroke detection. Unlike tie-rod cylinders, the riveted rolling-packed aluminum barrel cannot be disassembled, but it saves weight and space. The carbon steel rod features 20 um hard-chrome plating for wear resistance, and a heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10SU Is Used
PCB Router Clamping
Uses the 628 N push force at 0.5 MPa to hold small PCB panels firmly in place during high-speed CNC routing without vibrating the aluminum frame.
Carton Flap Folding
The 10mm stroke provides just enough extension to tuck minor carton flaps on a continuous packaging conveyor, fitting entirely within the narrow machine guard.
Connector Insertion Press
Drives a small electronic header into a socket on a semiconductor line, using the -S magnet and a DMSG solid-state switch to verify the 10mm insertion depth.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10SU the Right Cylinder?
If you need less force, step down to the 32mm bore (402 N push @0.5 MPa); if you require more power, step up to the 50mm bore (981 N push @0.5 MPa). For short-stroke clamping, this 10mm stroke is highly efficient. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact—choose the MBLC variant if your application requires an adjustable air cushion for heavier moving masses. Note that the plain MBL does not hold its load when air pressure is lost; pair it with an external rod lock or pilot-operated check valve if gravity or drift is a concern. Replacement match: 40mm bore, 10mm stroke, G1/4 port, PT thread, U flat-end back cover, no mounting accessory, with -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 MBL40X10SU 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 is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the base MBL40X10SU uses a fixed rubber bumper to absorb end-of-stroke impact. If you need an adjustable air cushion for faster cycling or heavier loads, you must select the MBLC variant.
