About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X300-CA
The AirTAC MBL20X300-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it yields 157 N of push force and 132 N of pull force across its 300 mm stroke. The CA pivot back cover allows the body to swing on a pin, making it ideal for arcing movements and angular load applications that a rigid flat-end mount cannot accommodate.
This SKU lacks the -S suffix, meaning no built-in magnet is present and a position sensor cannot be fitted. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion. The riveted rolling-packed barrel keeps the body light and compact, while the carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X300-CA Is Used
Textile Loom Guide Arm
Uses the CA pivot to arc a yarn guide across the weaving width, leveraging the 300 mm stroke while keeping the 157 N push force gentle enough for delicate threads.
Package Sorting Diverter
Swings a lightweight deflector flap on a packaging line, where the compact 20 mm bore fits between conveyor rollers and the clevis mount accommodates the angular pivot.
PCB Conveyor Transfer
Pushes unpopulated boards into a testing fixture, utilizing the 132 N pull force at 0.5 MPa to retract the arm without damaging sensitive electronic components.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X300-CA the Right Cylinder?
With a 300 mm stroke on an Ø8 mm rod, this cylinder is highly susceptible to side-load bending; always use an external guide or the CA pivot to prevent rod-bearing damage. If you need less reach, the neighbouring MBL20X250 offers a shorter stroke with the same 157 N push at 0.5 MPa. If you need more force, stepping up to the MBL25 bore increases output to 245 N push and 206 N pull at 0.5 MPa.
Because the fixed rubber bumper cannot be tuned, select the MBLC variant if your 300 mm move requires adjustable air cushioning for heavier loads. Note that this cylinder will drift and drop if air pressure is lost; use an external rod lock or pilot-operated check valve to hold a suspended load. Replacement requires matching the 20 mm bore, 300 mm stroke, G1/8 port, PT thread, and CA pivot 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 MBL20X300-CA FAQ
This 20 mm 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 uses a fixed rubber bumper for end-of-stroke impact absorption and does not have an adjustable air cushion.
No. Because the model code MBL20X300-CA lacks the -S suffix, it has no built-in magnet. You must choose an MBL variant with the -S suffix to use CMSG, DMSG, or EMSG electronic sensor switches for rod position detection.
