About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X55SCA
The AirTAC MBL40X55SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 0.5 MPa it generates 628 N of push force and 528 N of pull force, making it well suited for medium-duty clamping and ejection tasks within a 55 mm stroke. The riveted rolling-packed barrel crimps the front and back covers directly to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for position detection using CMSG reed or DMSG/EMSG electronic sensor switches. It features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, paired with a carbon-steel piston rod hardened with 20 um chrome plating for high wear resistance. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X55SCA Is Used
Lathe Chuck Ejection
Provides 628 N of push at 0.5 MPa to eject metal workpieces from a lathe chuck, using the CA pivot back cover to absorb slight angular misalignment during the ejection arc.
Bottle Divert Arm
Swings a diverter arm on a packaging line conveyor to route bottles, relying on the built-in magnet and a DMSG sensor to confirm the 55 mm stroke endpoint.
PCB Test Fixture
Applies 528 N of pull force to retract a testing probe head on a printed circuit board fixture, utilizing the compact riveted aluminum body to fit within dense test racks.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X55SCA the Right Cylinder?
For lower force needs, the 32 mm bore neighbor provides 402 N of push at 0.5 MPa, while stepping up to the 50 mm bore yields 981 N for heavier payloads. If your application requires end-of-stroke speed tuning, select the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion. Because the CA pivot back cover handles arcing loads, it helps offset the limited side-load tolerance of the 16 mm rod.
Keep in mind that a plain double-acting cylinder does not hold its load when air pressure is lost or the valve is centered; the rod will drift. For vertical or suspended loads, add an external pilot-operated check valve or a rod lock. To replace this unit, match the 40 mm bore, 55 mm stroke, 1/8" port size, PT thread form, CA pivot back cover, and the -S magnet requirement.
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 MBL40X55SCA FAQ
This 40 mm bore cylinder uses a 1/8" port and a Ø16 mm rod. 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.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (which requires the MBLC variant). This SKU includes a -S magnet, allowing you to mount CMSG reed or DMSG/EMSG electronic sensor switches for rod position detection.
