About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X430CA
The AirTAC MBL25X430CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 245 N push force at 0.5 MPa, making it well-suited for moving lighter loads over a 430 mm extension. The riveted rolling-packed barrel keeps the overall body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during motion. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø10 mm carbon-steel piston rod is protected by 20 µm hard-chrome plating for wear and corrosion resistance. 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.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X430CA Is Used
Textile Loom Tensioning
Swings via its CA pivot to maintain constant tension on textile loom guide arms across a 430 mm travel, using its 245 N push force to compensate for fabric weave variations.
Sorter Diverter Arm
Actuates a pivoting diverter arm on a small-package conveyor, where the CA clevis accommodates the arc of the swing and the compact body fits within the conveyor frame depth.
Pallet Wrapper Film Feed
Feeds stretch film on a pallet wrapping station, extending 430 mm to position the roll; the lightweight aluminum barrel reduces overhead carriage weight on the moving gantry.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X430CA the Right Cylinder?
With a 245 N push force at 0.5 MPa, stepping down to the MBL20 bore drops the output to 157 N, while stepping up to the MBL32 increases it to 402 N. For applications needing end-of-stroke energy absorption at higher speeds, the MBLC variant offers an adjustable air cushion instead of the base MBL's fixed rubber bumper. If you require a push-only or pull-only spring-return action in a compact body, consider the MSBL or MTBL single-acting lines.
At a 430 mm stroke, the Ø10 mm rod has low side-load tolerance; an unsupported mini rod this long can bend under lateral stress. The CA pivot back cover on this unit helps mitigate angular stresses, but you should still use an external guide rail or consider the MBLD double-rod anti-rotation type for rigid linear tracking. The fixed rubber bumper softens end impacts but does not hold the load—if air pressure drops or the valve centres, the rod will drift and drop, so fit an external rod lock or pilot-operated check valve for position holding.
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 MBL25X430CA FAQ
This double-acting 25 mm bore cylinder generates 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It operates at 0.15-1.0 MPa, travels at 30-800 mm/s, and uses a G1/8 port with an M10x1.25 rod-end thread.
No, this specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG position switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; if you need adjustable air cushioning for heavier or faster moving loads, you must specify the MBLC variant.
