About the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X400-CA
The AirTAC MBL50X400-CA is a double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial reach. Delivering 981 N of push force at 0.5 MPa (1374 N at 0.7 MPa), this 50 mm bore unit drives a 400 mm stroke via a Ø16 mm carbon steel rod plated with 20 μm hard chrome for high wear resistance. The riveted rolling-packed barrel keeps the overall body light and small, but the crimped construction means it is not designed to be disassembled or rebuilt like a traditional tie-rod cylinder.
This SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during motion. It uses a heterogeneous two-way piston seal that retains grease for extended operational life. Because this model lacks the -S suffix, it has no built-in magnet and cannot accept a CMSG, DMSG, or EMSG position sensor switch. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X400-CA Is Used
Indexing Gate Mechanism
Drives a 400 mm swing gate on a packaging sorter. The CA pivot back cover handles the arcing motion perfectly while the 981 N force at 0.5 MPa easily shifts the lightweight aluminum gate panel.
Tote Pusher Arm
Pushes empty totes from a conveyor line into a divert lane. The 400 mm stroke reaches across the belt, and the compact aluminum riveted barrel fits within the tight 60 mm side-frame clearance.
Vertical Bin Sweep
Sweeps small plastic components from a gravity bin into a chute. The 50 mm bore provides enough push (881 N pull) to overcome component bridging, while the fixed rubber bumper prevents harsh impact at full extension.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X400-CA the Right Cylinder?
This 50 mm bore provides 981 N push and 881 N pull at 0.5 MPa. If you need less force, step down to the 40 mm bore (628 N push at 0.5 MPa); if your load requires more power, step up to the 63 mm bore (1558 N push at 0.5 MPa). The base MBL uses a fixed rubber bumper, so if your 400 mm stroke carries a heavy mass at high speed and needs end-of-stroke deceleration, upgrade to the MBLC variant for an adjustable air cushion.
At 400 mm of travel, the Ø16 mm rod has low side-load tolerance and can bend if subjected to lateral forces without support. The CA pivot back cover on this unit helps by allowing angular alignment, but you should still use an external guide or consider the MBLD double-rod type to prevent binding. Note that the rubber bumper only softens end impact; it is not a lock, so the rod will drift if air pressure is lost or the valve is centred. Use an external pilot-operated check valve if the load must be held in place. Replacement match: 50 mm bore, 400 mm stroke, G1/4 port (PT thread form), CA pivot back cover, no magnet.

- ✓ 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 MBL50X400-CA FAQ
This double-acting 50 mm bore cylinder provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa. The 400 mm stroke is within the 500 mm maximum standard stroke limit for this bore size.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact; you must switch to the MBLC variant if your application requires adjustable air cushioning.
