About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40CA
The AirTAC MBL40X40CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 628 N push and 528 N pull force at 0.5 MPa, making it well-suited for short 40 mm stroke actuation tasks. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder.
This SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads. Because it lacks the -S suffix, a position sensor cannot be fitted to this specific unit. The carbon-steel piston rod features 20 µm hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40CA Is Used
Bottling Line Diverter
Swings a 40 mm stroke arm to route plastic bottles on a packaging conveyor using 628 N of push force.
Textile Guide Arm
Uses the CA pivot back cover to smoothly track and tension moving fabric webs without binding.
Carton Flap Folder
Provides 528 N pull force to tuck cardboard flaps prior to sealing in compact packing machinery.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40CA the Right Cylinder?
If you need slightly less force, the 32 mm bore offers 402 N push at 0.5 MPa; for heavier pushing, the 50 mm bore provides 981 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, so step up to the MBLC variant if your machine requires an adjustable air cushion for heavier masses. Since this is a double-acting cylinder, it does not hold position if air pressure drops—the rod will drift when exhausted. Use an external rod lock or pilot-operated check valve if the load must be held safely.
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 MBL40X40CA FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa push is 880 N, and the maximum theoretical force is 128 kgf at 1.0 MPa. The port size is G1/4.
This specific SKU lacks the -S magnet, so a position sensor cannot be fitted. It uses a fixed rubber bumper for end-of-stroke impact absorption; choose the MBLC variant if you need adjustable air cushioning.
