About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450CA
The AirTAC MBL40X450CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it suitable for moving moderate loads over its 450 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight body that is permanently sealed rather than bolted for disassembly.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular motion. Because it lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor. The carbon-steel piston rod features a 20 um hard-chrome plating, and the heterogeneous two-way piston seal actively retains grease for long-term wear resistance.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450CA Is Used
Textile Loom Guide
Drives a 450 mm yarn guide arm in a textile loom, using the CA pivot cover to swing smoothly with the arcing cam motion while applying 628 N of push force at 0.5 MPa.
Packaging Diverter
Actuates a 450 mm routing flap on a cardboard packaging conveyor, where the CA clevis accommodates the pivot arc and the compact riveted barrel fits inside the narrow machine frame.
Warehouse Sorter Arm
Pushes totes along a 450 mm sortation lane in a distribution hub, relying on the 528 N pull force to retract the diverter paddle clear of the main conveyor belt.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450CA the Right Cylinder?
If you need less thrust, the next size down is the 32 mm bore, which offers 402 N of push force at 0.5 MPa. For heavier loads, the 50 mm bore provides 981 N of push force. This 40 mm bore operates on a G1/4 port, uses an M12x1.25 rod-end thread, and has a PT (tapered) port thread form. If your cycle creates heavy end-of-stroke impacts, step up to the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion.
With a 450 mm stroke, the 16 mm rod is highly susceptible to bending under side loads. The CA pivot back cover on this unit is ideal for absorbing angular misalignment, but you should still use an external guide or consider the MBLD double-rod anti-rotation type for strict linear stability. Note that the fixed rubber bumper only softens end-of-stroke impact; it does not hold the load. If air pressure is lost, the rod will drift and drop, requiring an external rod lock or pilot-operated check valve for position holding.
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 MBL40X450CA FAQ
This 40 mm bore double-acting 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. It has a 450 mm stroke, uses a G1/4 port, and operates at speeds of 30-800 mm/s.
No, because this SKU lacks the -S suffix, it has no internal magnet and cannot accept a CMSG, DMSG, or EMSG sensor switch. For cushioning, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact; if you need adjustable end-cushioning for heavier loads, you must select the MBLC variant instead.
