About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200U
The AirTAC MBL40X200U is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. Operating at 0.5 MPa, it delivers 628 N of push force and 528 N of pull force across its 200 mm stroke, making it well-suited for mid-range actuation tasks. This genuine AirTAC unit features a rigid U flat-end rear cover for direct fixed mounting and uses a G1/4 port paired with a Ø16 mm carbon steel rod.
Unlike tie-rod bodies that unbolt for maintenance, this cylinder utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, prioritizing a lightweight, compact footprint over field rebuildability. The piston relies on a heterogeneous two-way seal that actively retains grease for long service life, while the rod is protected by 20 um hard-chrome plating to resist wear and corrosion. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accommodate a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200U Is Used
Package Diverting Arm
Pushes lightweight cardboard cartons on a packaging line using 628 N of thrust, fitting neatly into the narrow side-frame gaps of the conveyor structure.
Small Press Ejector
Kicks stamped metal small parts out of a die area with 528 N of retract pull force, where the 200 mm stroke clears the press bed safely.
Palletizing Stop Gate
Acts as a rigid physical stop for orienting incoming product totes on a roller bed, utilizing the fixed U flat-end cover to absorb repeated lateral impacts.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200U the Right Cylinder?
Selecting the MBL40X200U provides 628 N of thrust at 0.5 MPa. If your application requires less force, stepping down to the 32 mm bore yields 402 N of push force; if you need more power, the 50 mm bore offers 981 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion—if you need precise end-deceleration for heavier moving loads, consider the MBLC variant. Additionally, a plain double-acting cylinder like this does not hold its position if air pressure is lost or the valve is centered; the rod will drift, so an external pilot-operated check valve is required for drop prevention.
At a 200 mm stroke, the Ø16 mm piston rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, ensure the load is guided externally or switch to the MBLD double-rod type for anti-rotation support. This U flat-end back cover provides a rigid rear mount, but for arcing or angular movements, a CA pivot back cover paired with an SDB bracket would be necessary. The port thread form is default PT (tapered).
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 MBL40X200U FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. Increasing the pressure to 0.7 MPa yields 880 N of push force. The theoretical maximum force is 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a speed of 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Furthermore, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact; it does not have an adjustable air cushion. For adjustable cushioning, you must specify the MBLC variant.
