About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SU
The AirTAC MBL40X500SU is a double-acting aluminum mini round cylinder engineered for compact spaces requiring a long 500mm reach. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force. This genuine AirTAC component features a U flat-end back cover for rigid mounting and a built-in -S magnet for position detection.
Inside the riveted rolling-packed barrel, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon steel rod is protected by 20 µm hard-chrome plating to resist wear. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion. Because this SKU includes the -S magnet, it directly supports AirTAC CMSG (reed) and DMSG or EMSG (solid-state) sensor switches for precise end-position feedback.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SU Is Used
Pallet Diverters
Pushes lightweight pallets sideways at 628 N on a 500 mm stroke across a narrow conveyor belt, using the -S magnet to confirm full extension.
Vertical Tray Lifters
Elevates stacked component trays in a tight electronics assembly cell, relying on the 880 N push force at 0.7 MPa to overcome initial static friction.
Long-Reach Pin Extractors
Extracts alignment pins from deep machine pockets over a 500 mm travel, where the compact riveted aluminum body fits where standard profile cylinders cannot.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X500SU the Right Cylinder?
This 40 mm bore strikes a balance between the lighter 32 mm version (402 N push @0.5 MPa) and the larger 50 mm model (981 N push @0.5 MPa). Choose the MBL40 when you need more force than the 32 mm provides but lack the physical envelope for a 50 mm body. If your application requires softer end-stopping for heavy moving masses at speed, step up to the MBLC variant for its adjustable air cushion. For simple push or pull operations without continuous air supply, consider the single-acting MSBL or MTBL alternatives.
At 500 mm of stroke, the unsupported Ø16 mm piston rod is highly susceptible to side-load bending and rod-bearing wear. To prevent premature failure, guide the load externally or use a pivot mounting accessory instead of relying solely on the rigid U flat-end back cover. Note that a plain MBL does not hold its position if air pressure drops; the fixed rubber bumper softens impact but acts as neither a brake nor a lock. For exact replacement matching, specify: 40 mm bore, 500 mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and the -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 MBL40X500SU FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No, the base MBL40X500SU uses a fixed rubber bumper to absorb end-of-stroke impact and does not feature an adjustable cushion screw. If your 500 mm stroke application involves fast cycling or heavy loads that require deceleration tuning, you should select the MBLC variant which includes adjustable air cushioning.
