About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25CA
The AirTAC MBLC25X25CA is a compact double-acting aluminum mini cylinder engineered for short-stroke actuation. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. The 25 mm bore uses a G1/8 port and a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating to resist premature wear. This variant includes a CA pivot back cover, allowing the body to swing on a pin to absorb angular misalignment during arcing movements.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC model features a screw-adjustable pneumatic cushion at both ends. You tune the needle valve to decelerate the piston smoothly near the stroke limits, effectively minimizing end-cover impact and vibration on faster cycles. The riveted rolling-packed aluminum barrel keeps the assembly light and highly suited for tight spaces. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25CA Is Used
Pick-and-Place Swing Arms
Ideal for driving a short 25 mm swing arm in a packaging machine, where the CA pivot absorbs arcing loads and the air cushion prevents harsh stops at 245 N push force.
Package Flap Folding
Provides the precise 25 mm stroke needed to fold cardboard flaps on a carton sealing line, utilizing the tunable cushion to dampen impact during high-frequency cycling.
Bin Gate Diverting
Actuates a small diverter gate at a sorting station, with the CA clevis mounting accommodating the slight angular geometry shift as components are routed.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25CA the Right Cylinder?
The 25 mm bore is optimal when you need around 245 N of push at 0.5 MPa. If your application requires less force, stepping down to the 20 mm bore yields 157 N of push, while upgrading to the 32 mm bore provides 402 N for heavier payloads. The 25 mm stroke is highly compact, but if your machine cycle runs at high speeds or shifts a substantial mass, the MBLC adjustable air cushion is strongly preferred over the fixed bumper of the standard MBL to protect the end covers.
Because this SKU omits the -S magnet, it cannot accept an AirTAC CMSG, DMSG, or EMSG sensor switch for rod position detection. If your sequence requires end-of-stroke feedback, you must select an -S designated model instead. Remember that the adjustable cushion only decelerates the piston near the ends; it does not lock the rod or hold position if air pressure is lost or the valve centers. For true load holding without live air, install an external rod lock or pilot-operated check valve.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25CA FAQ
This 25 mm bore cylinder features a G1/8 port and a M10x1.25 rod-end thread. At 0.5 MPa it provides 245 N of push force and 206 N of pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The MBLC25X25CA uses a screw-tunable pneumatic needle at both ends to trap and exhaust air smoothly as the piston nears the stroke limits. You adjust the needle to match your load and speed, decelerating the rod to cut impact noise and vibration. It functions strictly as an end-of-stroke damper, not a load lock or brake.
