About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450U
The AirTAC MBL40X450U is a double-acting aluminum mini round cylinder engineered for compact spaces requiring a long 450 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it suitable for moving heavier jigs or workpieces over an extended linear travel. The U suffix designates a flat-end rigid rear cover for direct mounting.
This SKU lacks the -S magnet option, meaning it cannot accept an AirTAC CMSG, DMSG, or EMSG position sensor. End-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable cushion screw. To survive the leverage of a 450 mm extension, the carbon steel rod relies on its 20 µm hard-chrome plating to resist wear, though an external guide is strongly recommended to protect the Ø16 mm rod from bending.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450U Is Used
Pallet Transfer Pusher
Pushes loaded pallets sideways onto a secondary conveyor line, utilizing the 628 N push force to overcome friction over the 450 mm travel distance.
Deep Bin Escapement
Acts as a stopper gate deep inside a parts feeder chute, cycling the 450 mm stroke to release heavy nested components one row at a time.
Long-Reach Tool Staging
Deploys a secondary machining head or probe into a CNC workzone, using the compact aluminum body to fit within tight machine guarding.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X450U the Right Cylinder?
Selecting the MBL40X450U provides 628 N push at 0.5 MPa. If your payload is lighter, stepping down to the 32 mm bore yields 402 N push and saves space; if you need more force, the 50 mm bore provides 981 N push. For end-position damping of heavy fast loads, upgrade to the MBLC variant which adds an adjustable air cushion instead of the standard fixed rubber bumper.
Because this 450 mm stroke exceeds the 300 mm threshold, the small 16 mm rod is highly susceptible to side-load bending. Use a CA pivot back cover or an external linear guide to support the load. Note that this cylinder does not hold its position if air pressure is lost—the rubber bumper only softens impact, so add a pilot-operated check valve if you need drop prevention. Replacement match: 40 mm bore, 450 mm stroke, G1/4 port, PT thread, U flat-end 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 MBL40X450U 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 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. This specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke damping. For adjustable air cushioning, you must specify the MBLC variant.
