About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X50-CA
The AirTAC MBL20X50-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 157 N and a pull force of 132 N at 0.5 MPa, making it well-suited for short 50 mm stroke movements in confined assemblies. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a CA pivot (clevis) back cover that allows the cylinder to swing on a pin, accommodating arcing or angular loads. It uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG sensor switch for rod position detection.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X50-CA Is Used
PCB Ejection Arm
Provides the precise 50 mm stroke and 157 N push to eject populated printed circuit boards from a testing fixture without damaging delicate traces.
Pouch Forming Guide
Swings on its CA pivot bracket to guide packaging film into a vertical pouch sealing jaw, utilizing the compact 20 mm body to fit within narrow machine guarding.
Sample Tube Sorting
Actuates a low-friction routing gate for clinical sample tubes, relying on the 132 N pull force at 0.5 MPa to reliably retract the diverter arm.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X50-CA the Right Cylinder?
Choose this 20 mm bore when you need 157 N of push force at 0.5 MPa in a very compact footprint. If your application requires less force, there is no smaller bore in the MBL line, so you would need to look outside the mini round family. If you need more power, stepping up to the 25 mm bore increases your push force to 245 N. For applications needing end-of-stroke deceleration for heavier moving loads, consider the MBLC variant which adds an adjustable air cushion. If you need the rod to stay put after a loss of air pressure, this cylinder will drift or drop, so an external rod lock or pilot-operated check valve is required. This SKU uses a G1/8 port, PT thread form, M8x1.25 rod-end thread, and the 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 MBL20X50-CA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N, with a theoretical maximum force of 32 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, this specific SKU lacks the -S magnet suffix, meaning it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact. If you need adjustable air cushioning, you must step up to the MBLC variant.
