About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SCA
The AirTAC MBL40X100SCA is a double-acting aluminum mini round cylinder engineered for compact installations where a standard profile body will not fit. It yields a push force of 628 N and a pull force of 528 N at 0.5 MPa, making this 40 mm bore, 100 mm stroke configuration well-suited for mid-range actuation in tight machine cells. The riveted rolling-packed barrel crimps the front and back covers directly to the tube, yielding a featherweight body that is permanently sealed rather than designed for field teardown like a tie-rod unit.
This specific SKU integrates a built-in magnet (-S) for electronic position sensing using AirTAC CMSG reed or DMSG/EMSG solid-state switches. It pairs that sensing capability with a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion, while the heterogeneous two-way piston seal actively retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SCA Is Used
Packaging Line Diverter
Swings a lightweight routing gate on a high-speed packaging conveyor using its CA pivot back cover, relying on 628 N of thrust at 0.5 MPa to snap parts into secondary lanes.
Textile Yarn Guide
Pivots a thread guide arm across a weaving loom, where the compact riveted barrel fits into narrow machine frames and the DMSG sensor confirms the shift position.
Small Parts Ejector
Pushes molded plastic components out of a tight injection mold cavity, using the 100 mm stroke to clear the tooling before the next cycle begins.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SCA the Right Cylinder?
If your application requires less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if you need heavier thrust, step up to the 50 mm bore (981 N push at 0.5 MPa). At 100 mm of stroke, the 16 mm rod maintains good rigidity, but for any stroke extension beyond 300 mm you should add an external guide or switch to the MBLD double-rod type to prevent rod-bearing bending under side load. Choose the MBLC variant if your cycle speed demands adjustable air cushioning rather than the base fixed rubber bumper. Note that a plain MBL cannot hold a load if air pressure drops; the bumper softens end-of-stroke impact but acts as neither a lock nor a brake, so fit an external rod lock for fail-safe holding. This exact replacement requires a 40 mm bore, 100 mm stroke, G1/4 port, PT thread, CA pivot back cover, and a built-in 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 MBL40X100SCA FAQ
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts. It does not feature an adjustable cushion screw. If your application requires adjustable air cushioning to handle heavier moving masses, you must select the MBLC variant.
