About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450SCA
The AirTAC MBL40X450SCA is a compact double-acting aluminum mini round cylinder engineered for tight assembly spaces. At 40mm bore, it generates 628N push and 528N pull force at 0.5MPa, making it well-suited for moving moderate loads over its 450mm stroke. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, prioritizing a lightweight footprint rather than tie-rod rebuildability.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, which is critical given the 450mm stroke. The included -S magnet enables position detection via CMSG (reed) or DMSG/EMSG (electronic) switches. The carbon-steel piston rod features 20um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for extended operational life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450SCA Is Used
Transfer Arm Actuation
Drives a 450mm arcing transfer arm in packaging machinery, utilizing the CA pivot back cover to handle angular movement while pushing 628N at 0.5 MPa.
PCB Sorting Gate
Indexes sorting gates on electronics assembly lines where the -S magnet triggers a DMSG solid-state switch to confirm rod extension at 880N push force.
Pallet Diverters
Actuates diverter arms on compact pallet conveyors, relying on the riveted aluminum barrel to save space while managing 528N pull force.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450SCA the Right Cylinder?
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the 50mm bore provides 981N push at 0.5MPa. If your application requires adjustable end-of-stroke deceleration rather than the standard fixed rubber bumper, select the MBLC variant. For single-acting push or pull operations, consider the MSBL or MTBL series.
With a 450mm stroke, the 16mm rod has low side-load tolerance and requires external guidance to prevent rod-bearing bending. The CA pivot back cover on this unit helps manage angular misalignment. Note that a plain MBL will drift and drop if air pressure is lost, as the rubber bumper only softens end-impact without locking the load. Replacement match: 40mm bore, 450mm stroke, 1/8" port, PT thread, CA back cover, SDB pivot bracket, -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 MBL40X450SCA FAQ
At 0.5 MPa it provides 628N push and 528N pull. At 0.7 MPa the push force is 880N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. If you need an adjustable air cushion for heavier or faster moving loads, you must step up to the MBLC variant.
