About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350-CA
The AirTAC MBL40X350-CA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body cannot fit. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making this 40 mm bore variant well-suited for moving heavier jigs or actuating long-travel mechanisms across a 350 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a light, compact envelope that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing and angular loads, a critical feature for a 350 mm stroke. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear resistance. Note that this configuration lacks a built-in magnet, so it cannot support a CMSG, DMSG, or EMSG position sensor. The end-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350-CA Is Used
PCB Shuttle Conveyance
Drives a 350 mm travel shuttle board in a PCB assembly tester, using the CA pivot back cover to absorb slight angular misalignment while pushing 628 N at 0.5 MPa.
Packaging Flap Diverter
Actuates a long-arc routing flap on a packaging conveyor, swinging heavy cardboard carton traffic at 880 N of push force at 0.7 MPa.
Warehouse Tote Pusher
Ejects loaded storage totes from a tight vertical lift station where a standard ISO 15552 profile cylinder would exceed the available machine footprint.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X350-CA the Right Cylinder?
If you need less force, step down to the 32 mm bore which provides 402 N push at 0.5 MPa; if your application requires more power, step up to the 50 mm bore which delivers 981 N push at 0.5 MPa. Choose the MBLC variant if your cycle times demand adjustable air cushioning to soften heavy end-of-stroke impacts, or the MSBL/MTBL single-acting series if you only need spring-return movement in one direction.
Because this cylinder lacks an adjustable cushion and uses a fixed rubber bumper, it cannot hold a load if air pressure is lost or the valve is centered—the rod will drift. For a 350 mm stroke, the small Ø16 mm rod has limited side-load tolerance, so the CA pivot cover is highly beneficial for managing angular stress; you should also use an external guide rail to prevent rod-bearing bending. Replacement match: 40 mm bore, 350 mm stroke, 1/8" 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 MBL40X350-CA FAQ
This 40 mm bore cylinder uses a 1/8" port and a Ø16 mm rod with an M12x1.25 rod-end thread. It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; you must upgrade to the MBLC variant to get adjustable air cushioning.
