About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SCA
The AirTAC MBL40X500SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, making this 40 mm bore variant ideal for moving heavier actuators over its full 500 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight, compact body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches to confirm end-of-stroke position. The CA pivot back cover allows the cylinder to swing on a pin, accommodating arcing or angular loads, while the carbon-steel piston rod features 20 um hard-chrome plating for high wear resistance. A heterogeneous two-way piston seal permanently retains grease for long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SCA Is Used
Textile Loom Guide
Drives a 500 mm weft guide mechanism in compact weaving looms, utilizing the CA pivot to accommodate the arcing travel path without binding the 16 mm rod.
Pallet Transfer Pusher
Indexes pallets along a narrow conveyor line, where the 628 N push force at 0.5 MPa easily shifts loads within the 500 mm stroke range.
Vertical Parts Elevator
Lifts stacked components between machine tiers, using the -S magnet with a DMSG electronic switch to verify the upper position.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SCA the Right Cylinder?
To size this actuator both ways, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa for lighter duties, while stepping up to the 50 mm bore provides 981 N for heavier mechanisms. Because this is a 500 mm stroke on a mini rod, the 16 mm piston rod has low side-load tolerance; an external guide or the CA pivot back cover is mandatory to prevent rod-bearing bending under lateral stress. For dual-side anti-rotation support, consider the MBLD double-rod type.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; if your 500 mm move requires adjustable air cushioning for heavier masses, step up to the MBLC variant. Remember that a plain MBL does not hold its load when air pressure is lost or the valve is centered, as the rod will drift; use an external pilot-operated check valve for position holding. This SKU features a G1/4 port, PT thread form, M12x1.25 rod-end thread, and a CA pivot cover.
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 MBL40X500SCA FAQ
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. The 500 mm stroke is a non-standard made-to-order length (standard max is 500 mm).
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier moving masses, select the MBLC variant instead.
