About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X225SCA
The AirTAC MBL40X225SCA is a double-acting aluminum mini round cylinder engineered for compact actuation in tight machine spaces. Operating at 0.5 MPa, it provides 628 N of push force and 528 N of pull force, making it well-suited for mid-range stroke tasks requiring 225 mm of travel. This specific SKU features a CA pivot back cover that allows the body to swing on a pin, accommodating arcing or angular loads during motion.
Unlike tie-rod cylinders, the MBL uses a riveted rolling-packed barrel where the covers are crimped to the tube, ensuring a lightweight footprint but making it non-rebuildable. The carbon-steel piston rod is hardened with 20 um chrome plating for wear resistance, while the heterogeneous two-way piston seal retains grease for extended operational life. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion. The built-in magnet (-S) enables position detection using AirTAC CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X225SCA Is Used
Textile Loom Guide Arm
Swings a thread guide arm across a 225 mm path. The CA pivot back cover absorbs lateral misalignment while the 628 N force at 0.5 MPa ensures positive positioning.
Packaging Flap Folder
Folds corrugated carton flaps on a continuous packaging line. The compact aluminum body fits between conveyor rollers, and the built-in magnet confirms flap closure.
Bottling Line Diverter
Pushes glass bottles into a labeling station diverter. The 225 mm stroke provides the necessary reach, while the 880 N push force at 0.7 MPa handles heavy liquid-filled containers.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X225SCA the Right Cylinder?
If your application requires less force, the MBL32 bore provides 402 N of push at 0.5 MPa, while stepping up to the MBL50 yields 981 N for heavier loads. For this 225 mm stroke, the 16 mm rod is susceptible to bending under side loads; utilizing the CA pivot back cover with an SDB bracket helps mitigate this, though an external guide or the MBLD double-rod type is recommended for strict anti-rotation. The fixed rubber bumper softens end impacts but does not lock the rod—if the air supply is lost or the valve is centered, the load will drift and requires an external pilot-operated check valve to hold position. For applications needing softer end-of-stroke deceleration, the MBLC variant offers an adjustable air cushion. This SKU is configured with a G1/4 port, PT thread form, M12x1.25 rod-end thread, and a CA pivot back cover.
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 MBL40X225SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder delivers 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; it does not have an adjustable air cushion (for that, choose the MBLC variant). This S-coded SKU includes a built-in magnet for use with AirTAC CMSG, DMSG, or EMSG sensor switches to detect rod position.
