About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X350-CA
The AirTAC MBL20X350-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 20mm bore and 350mm stroke, it generates 157 N of push force and 132 N of pull force at 0.5 MPa. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, keeping the body exceptionally light for small-footprint assemblies. This specific SKU uses a CA pivot back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads during motion.
Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The piston relies on a heterogeneous two-way seal that retains grease for long service life, while the carbon-steel rod features 20 μm hard-chrome plating to resist wear and corrosion. The base end-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but is not an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X350-CA Is Used
Flow-Wrap Film Splicing
Guides the pivoting film splicing arm on a continuous flow-wrapper, using the CA clevis to swing the 350mm stroke clear of the cutting head during roll changes.
PCB Shuttle Extraction
Extracts populated PCB panels from a test fixture, where the 157 N push force at 0.5 MPa is sufficient to separate the board without stressing edge connectors.
Diverter Gate Actuation
Drives a lightweight sorting diverter on a conveyor system, utilizing the compact 20mm bore to fit between tight belt rollers while handling arcing loads via the pivot mount.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X350-CA the Right Cylinder?
Stepping down in force is possible with the MBL16 bore (if available) or stepping up to the MBL25, which provides 245 N push at 0.5 MPa for heavier payloads. If your application requires end-of-stroke speed regulation for faster cycles, switch to the MBLC variant for its adjustable air cushion. For single-direction push or pull tasks, consider the MSBL or MTBL single-acting models. Keep in mind that a plain MBL does not hold its load when air pressure is lost or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve if position must be maintained.
At 350mm of stroke, the Ø8mm piston rod is highly susceptible to bending under side loads. The CA clevis back cover on this unit helps mitigate angular stresses by allowing the body to pivot, but an external guide rail is strongly recommended to prevent rod-bearing damage. Alternatively, the MBLD double-rod type provides inherent anti-rotation for long linear travels. Replacement requires matching the 20mm bore, 350mm stroke, G1/8 port, PT thread form, CA pivot back cover, and 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 MBL20X350-CA FAQ
This 20mm bore cylinder delivers 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s, uses a G1/8 port, and accepts an M8x1.25 rod-end thread.
No, the base MBL20X350-CA uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, you must step up to the MBLC variant.
