About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30SCA
The AirTAC MBL20X30SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 157 N of push force at 0.5 MPa, this 20 mm bore, 30 mm stroke unit is built for light-duty positioning. Its riveted rolling-packed barrel permanently crimps the covers to the tube, yielding a lightweight footprint that is not designed to be disassembled like a tie-rod body.
This specific SKU includes a built-in magnet (-S) for rod position detection via CMSG reed or DMSG/EMSG electronic switches. It also features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The Ø8 mm carbon-steel rod is plated with 20 µm of hard chrome to resist wear and corrosion, while the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30SCA Is Used
PCB Edge Guide
Pushes lightweight printed circuit boards into edge clamps during automated optical inspection with 157 N of precise force.
Vial Sorting Gate
Acts as a compact diverter arm on a 30 mm stroke to route small pharmaceutical vials down the correct packaging lane.
Pouch End-Seal Tension
Maintains light, consistent tension on thin film pouches feeding into a rotary sealing jaw using its CA pivot to follow web weave.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30SCA the Right Cylinder?
At 157 N push at 0.5 MPa, this bore is the smallest in the range; stepping up to the 25 mm bore yields 245 N if your application needs more force. If your motion control requires end-of-stroke deceleration rather than the standard fixed rubber bumper, select the MBLC variant for its adjustable air cushion. Note that a plain MBL cannot hold a load if air pressure is lost—the rod will drift—so use an external rod lock for safety-critical holding. Replacement match: 20 mm bore, 30 mm stroke, G1/8 port, PT thread, CA pivot back cover, with -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 MBL20X30SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa the push increases to 220 N, and the theoretical maximum force is 32 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. You must step up to the MBLC variant for adjustable air cushioning.
