About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X225-CA
The AirTAC MBL20X225-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it generates 157 N of push force and 132 N of pull force, making it well-suited for light-duty 225 mm linear positioning tasks. The riveted rolling-packed barrel keeps the body light and compact, though it is not designed to be disassembled like a tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø8 mm carbon-steel rod features 20 μm hard-chrome plating for wear and corrosion resistance.
This specific SKU includes a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during movement. Because this model lacks the -S suffix for a built-in magnet, it cannot be fitted with a CMSG, DMSG, or EMSG position sensor switch. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable air cushion (which requires the MBLC variant).

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X225-CA Is Used
Textile Yarn Guide
Swings on a pin via the CA clevis to track moving yarn strands across a 225 mm stroke, using the 157 N push force to maintain light tension without stressing the fiber.
PCB Shuttle Pusher
Ejects light printed circuit boards from a test fixture; the compact aluminum riveted body fits within dense electronics testing racks while the fixed rubber bumper softens the ejection impact.
Packaging Flap Deflector
Pivots to guide cardboard carton flaps during case erecting, where the 132 N pull force retracts the Ø8 mm chrome-plated rod reliably in confined packaging machine frames.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X225-CA the Right Cylinder?
With a 157 N push force at 0.5 MPa, this 20 mm bore cylinder handles very light loads. If your application requires less force, you are already at the smallest standard MBL bore. If you need more power, stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa. The CA pivot back cover on this unit is ideal for arcing loads, but if you need fixed rigid mounting, the default U flat-end cover is the better choice. Keep in mind that a plain MBL does not hold its position when air pressure is lost or exhausted; the rod will drift. Use an external rod lock or pilot-operated check valve if gravity or load must be held safely.
For a 225 mm stroke on an Ø8 mm rod, the small rod diameter means low side-load tolerance. Long unsupported strokes risk rod-bearing bending under side loads. To manage this, leverage the CA pivot back cover with an SDB bracket, add an external guide, or switch to the MBLD double-rod type for anti-rotation support. Replacement parts must match the 20 mm bore, 225 mm stroke, G1/8 port, PT thread, and CA back cover.
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 MBL20X225-CA FAQ
This double-acting cylinder has a 20 mm bore and operates on filtered air at 0.15-1.0 MPa. The force output is 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 runs at speeds of 30-800 mm/s.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, you must upgrade to the MBLC variant.
