About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30CA
The AirTAC MBL20X30CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.15-1.0 MPa, this 20mm bore configuration generates 157 N of push force and 132 N of pull force at 0.5 MPa, making it well-suited for short 30mm linear positioning tasks. The body utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, ensuring a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads during operation. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø8 mm carbon steel piston rod features 20 µm hard-chrome plating for wear and corrosion resistance. Because this model lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. End-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30CA Is Used
PCB Pick & Place Pivot
Ideal for driving a short 30mm pick-and-place arm in electronics assembly, where the CA clevis allows the tiny 157N actuator to swing slightly while indexing components.
Connector Insertion Arm
Provides the precise 30mm linear push needed to seat ribbon cable connectors into PCB sockets, utilizing the compact 20mm bore to fit between dense conveyor lanes.
Packaging Flap Deflector
Pivots a small guide flap on a carton sealing machine, using the CA pivot back cover to accommodate the angular motion as cardboard packaging passes through.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X30CA the Right Cylinder?
Select the MBL20X30CA when your mechanism requires a compact actuator with a short 30mm stroke and the ability to pivot under angular load. If you need slightly more force, stepping up to the 25mm bore yields 245 N of push force at 0.5 MPa; conversely, if you need less force and an even smaller footprint, this 20mm bore is the smallest available option in the series, providing 157 N. For applications requiring faster cycle speeds with heavier loads, consider the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
When sizing this cylinder, remember that the fixed rubber bumper only softens the end-of-stroke impact; it is not a locking mechanism. If your load must be held in place when air pressure is exhausted or the valve is centered, you must integrate an external rod lock or a pilot-operated check valve, as the plain MBL will drift or drop. For replacement, verify the 20mm bore, 30mm stroke, G1/8 port size, PT thread form, and CA pivot 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 MBL20X30CA FAQ
At 0.5 MPa, this 20mm bore cylinder outputs 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It operates at a speed of 30-800 mm/s.
No, because this SKU lacks the -S suffix for a built-in magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke deceleration; if you need adjustable air cushioning, you must step up to the MBLC variant.
