About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350CA
The AirTAC MBLC25X350CA is a double-acting aluminum mini cylinder with a 25 mm bore and 350 mm stroke. It delivers 245 N of push force at 0.5 MPa and uses a G1/8 port. A CA pivot back cover allows the body to swing on a pin, absorbing angular misalignment during arcing movements. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG position sensor.
This model features a screw-adjustable air cushion at both ends. You tune the needle to smoothly decelerate the piston near the stroke limits, protecting the end covers from impact on longer, faster moves. The riveted rolling-packed aluminum barrel keeps the body compact, while the 20 µm hard-chrome plating on the carbon-steel rod resists wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350CA Is Used
Textile Loom Weft Feeder
Swings a 245 N guide arm through an arcing 350 mm path using the CA pivot, relying on the tuned air cushion to stop the arm gently without stressing the end cover.
Packaging Flap Folder
Pushes carton flaps on a high-speed line, where the adjustable needle cushions the 350 mm extension to prevent slamming cardboard goods at 0.5 MPa.
Wood Tray Stacker
Indexes thin wooden slats upward; the CA clevis accommodates off-axis load shifts while the hard-chrome rod survives repetitive 350 mm strokes.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350CA the Right Cylinder?
If you need less reach or force, step down to the 20 mm bore, which yields 157 N of push at 0.5 MPa. For heavier payloads, the 32 mm bore provides 402 N of push at 0.5 MPa. Choose this MBLC over the base MBL when your cycle speed is high enough that a fixed rubber bumper would fail to absorb the kinetic energy.
At 350 mm of travel, a Ø10 mm rod is highly susceptible to side-load bending. Use an external guide rail, leverage the CA pivot bracket to prevent binding, or switch to an MBLD double-rod cylinder. This PT-threaded cylinder does not hold position if air pressure drops; the air cushion only decelerates near the ends and acts as no brake.
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 MBLC25X350CA FAQ
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 and pull to 289 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, it has no internal magnet and cannot accept a CMSG, DMSG, or EMSG switch. You must use external mechanical or proximity sensors for position detection.
