About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15CA
The AirTAC MBL40X15CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push force at 0.5 MPa and utilizes a short 15 mm stroke for rapid, localized actuation. The riveted rolling-packed barrel permanently crimps the covers to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod unit.
This specific SKU features a CA pivot back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features 20 um hard-chrome plating for superior wear and corrosion resistance. Because this model lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15CA Is Used
Pick-and-Place Pivot Arm
Ideal for a short-throw robotic arm joint needing 628 N push to swing a lightweight gripper between two conveyor lanes.
Package Diverter Flap
Provides a quick 15 mm stroke to nudge small cartons on a packaging line, with the CA clevis allowing the flap to pivot smoothly.
PCB Test Socket Clamp
Applies precise 528 N pull force to hold a circuit board firmly against electrical test pins within a densely packed semiconductor fixture.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15CA the Right Cylinder?
Choose the MBL40X15CA when your mechanism requires a short 15 mm stroke and a CA clevis mount to absorb angular linkage movement. If you need less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if your application demands more power, step up to the 50 mm bore (981 N push at 0.5 MPa). The 40 mm bore uniquely bridges these classes using a G1/4 port and a Ø16 rod.
This cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable air cushion (which requires the MBLC variant). A plain MBL does not hold its position if air pressure is lost; the rod will drift. For load-holding safety without live pressure, install an external pilot-operated check valve. Replacement match: 40 mm bore, 15 mm stroke, G1/4 port, PT thread, CA pivot back cover, no magnet.
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 MBL40X15CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, the push force increases to 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No. Because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, you must specify the MBLC variant.
