About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X80SCA
The AirTAC MBL20X80SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It generates 157 N of push force and 132 N of pull force at 0.5 MPa, making it suited for light-duty positioning over its 80 mm stroke. 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 specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, and a built-in magnet (-S) for non-contact position detection using AirTAC CMSG, DMSG, or EMSG sensor switches. The Ø8 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear resistance, while a heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X80SCA Is Used
PCB Router Gantry
Drives a light pick-place head on a PCB depaneling router where the 157 N push force at 0.5 MPa is sufficient to plunge a routing bit, and the CA pivot absorbs minor gantry misalignment.
Carton Flap Diverter
Swings a small guide flap on a packaging line to redirect small cartons, using the 80 mm stroke and pivot cover to maintain smooth motion without binding in a confined space.
Microplate Lid Lifter
Lifts thin plastic lids off assay microplates in a lab automation cell, relying on the built-in magnet to trigger a DMSG solid-state switch and confirm the 80 mm open position.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X80SCA the Right Cylinder?
If you need slightly less force, the adjacent MBL16 bore offers a smaller footprint, or you can step up to the MBL25 bore which provides 245 N push at 0.5 MPa for heavier loads. Because this base MBL uses a fixed rubber bumper rather than an adjustable air cushion, select the MBLC variant if your 80 mm stroke requires softer end-of-stroke deceleration for faster cycling.
This cylinder does not hold its load when air pressure is lost or exhausted, as the rubber bumper only softens impact and acts as neither a lock nor a brake. Use an external rod lock or pilot-operated check valve if position holding is required. Replacement matching requires a 20 mm bore, 80 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S 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 MBL20X80SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact and is not adjustable. If you need adjustable air cushioning for heavier or faster moving loads, you must step up to the MBLC variant.
