About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100U
The AirTAC MBL40X100U is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile cylinder will not fit. It provides a robust 628 N push force and 528 N pull force at 0.5 MPa, making this 100 mm stroke variant well suited for moving heavier small-part payloads. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating a lightweight assembly that is permanently sealed rather than bolted together.
This specific SKU features a U flat-end back cover for rigid, fixed mounting. The piston rod is carbon steel with 20 um hard-chrome plating for wear and corrosion resistance, while a heterogeneous two-way piston seal retains grease for a long service life. Because this model lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100U Is Used
Packaging Conveyor Diverter
With 628 N of push force at 0.5 MPa, this 100 mm stroke cylinder actuates heavy cardboard lane diverts on high-speed packaging conveyors where a compact footprint is required.
CNC Lathe Bar Feeder
The 100 mm stroke and 528 N pull force are ideal for gripping and retracting steel bar stock in an automated lathe feeder, utilizing the rigid U flat-end cover for stable mounting.
Palletizing Stop Gate
Provides a sturdy 880 N push force at 0.7 MPa to halt heavy loaded pallets on a roller conveyor, fitting neatly into the tight side-frame gaps of the palletizer.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100U the Right Cylinder?
If you need less force, step down to the MBL32 bore (402 N push @0.5 MPa); if your application demands more power, step up to the MBL50 bore (981 N push @0.5 MPa). The U flat-end back cover provides a rigid rear mount, but if your mechanism creates arcing or angular loads, switch to the CA pivot cover or pair the cylinder with an SDB pivot bracket. This base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for faster cycle speeds or heavier moving masses, select the MBLC variant with adjustable air cushion.
Remember that a plain MBL does not hold its load if air pressure is lost or the valve is centered, as the rod will drift without live pressure. Use an external rod lock or pilot-operated check valve if position holding is critical. Replacement match: 40 mm bore, 100 mm stroke, G1/4 port, PT thread, U flat-end back cover, no 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 MBL40X100U 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. Because this SKU lacks the -S suffix for a built-in magnet, it cannot accept a CMSG, DMSG, or EMSG sensor switch. You must select an MBL40X100S model to enable position detection.
