About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350SCA
The AirTAC MBL40X350SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force across its 350 mm stroke. This specific SKU features a CA pivot back cover, allowing the cylinder body to swing on a pin to absorb arcing or angular loads during motion.
Unlike tie-rod bodies that unbolt for maintenance, this unit utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube for maximum lightness. The carbon steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion. Because this model includes the -S suffix, it has a built-in magnet for position detection using AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensor switches. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion screw.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350SCA Is Used
Textile Loom Tensioning
Uses the 628 N push force and CA pivot mount to maintain consistent tension on yarn guides, absorbing angular deflection across the 350 mm travel.
Package Sorting Diverter
Swings a diverter arm on a packaging line; the -S magnet triggers a DMSG solid-state sensor to confirm stroke completion at high cycling speeds.
Warehouse Tray Pusher
Pushes cardboard trays onto lower-tier rollers, relying on the fixed rubber bumper to prevent harsh impact at the end of the 350 mm extension.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350SCA the Right Cylinder?
Selecting the MBL40X350SCA gives you a 40 mm bore with a 350 mm stroke, ported at G1/4 with PT threads. If you need less force, step down to the 32 mm bore (402 N push @0.5 MPa); if your application requires more thrust, step up to the 50 mm bore (981 N push @0.5 MPa). For faster or heavier 350 mm moves that require end-of-stroke speed tuning, choose the MBLC variant which adds an adjustable air cushion. If you only need a one-way push or pull, the MSBL or MTBL single-acting cylinders (available in 40 mm bore) are simpler alternatives.
At 350 mm of travel, the Ø16 mm rod is highly susceptible to bending under side loads; the CA clevis mount on this unit helps mitigate this by allowing the cylinder to pivot, but you should still use an external guide or consider the MBLD double-rod type for rigid anti-rotation. Note that a plain MBL cannot hold its position or load when air pressure is lost—the rubber bumper only softens the impact, so add an external rod lock or pilot-operated check valve if gravity or drift is a concern.
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 MBL40X350SCA 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, the base MBL40X350SCA uses a fixed rubber bumper to soften the end-of-stroke impact and cannot be adjusted. If your 350 mm stroke requires tunable deceleration for heavier loads, you must use the MBLC variant which features an adjustable air cushion.
