About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SCA
The AirTAC MBL40X200SCA 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, making it highly effective for moving moderate loads across a 200 mm stroke. The riveted rolling-packed barrel design permanently crimps the front and rear covers to the tube, yielding a light, space-saving body that is not designed to be disassembled like a traditional tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion.
This specific SKU includes a built-in magnet (-S) for position sensing via CMSG reed or DMSG/EMSG electronic switches, and a CA pivot (clevis) back cover. The CA rear allows the cylinder body to swing freely on a pin, making it the superior choice for arcing or angular load paths where a rigid flat-end mount would bind. As a base MBL model, end-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable air cushion (which requires stepping up to the MBLC variant).

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SCA Is Used
Pick-and-Place Gantry Arms
Ideal for articulated transfer arms moving electronic components between conveyor belts. The 628 N push force at 0.5 MPa handles part weight securely, while the CA pivot back cover accommodates the natural arcing motion of the swing mechanism without binding.
Packaging Flap Tucking
Drives a mechanical arm that tucks cardboard flaps on carton sealing machines. The 200 mm stroke provides the necessary reach into the folding mechanism, and the built-in magnet allows a DMSG sensor to trigger the glue gun at the exact end of travel.
Diverter Gate Actuation
Pivots a sorting gate on a logistics conveyor to route parcels. The clevis mount absorbs the angular momentum of the swinging gate, and the fixed rubber bumper quietly absorbs the end-of-stroke impact without requiring adjustment screws.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SCA the Right Cylinder?
Selecting this 40 mm bore depends on your force and motion requirements. Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to the 50 mm bore increases it to 981 N. If your application only needs to push or pull without live air pressure holding the load, consider the single-acting MSBL or MTBL variants. Note that a plain double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the rod will drift. For load-holding safety, add an external rod lock or a pilot-operated check valve.
With a 200 mm stroke, the unsupported Ø16 mm rod is highly susceptible to side-load bending. The CA pivot back cover on this SKU directly mitigates this by allowing the body to swing on its pin, keeping the rod aligned with the load's arc. For strictly linear heavy moves, pair the cylinder with an external guide rail or switch to the MBLD double-rod anti-rotation type. Replacement match: 40 mm bore, 200 mm stroke, G1/4 port, PT thread, CA pivot back cover, S magnet.
Quick checklist

- ✓ 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 MBL40X200SCA 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 is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa.
No. The base MBL40X200SCA uses a fixed rubber bumper to soften the end-of-stroke impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster-moving loads, you must use the MBLC variant.
