About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SU
The AirTAC MBLC25X450SU is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering a 245 N push force at 0.5 MPa, it uses a 10 mm carbon-steel rod with a 20 µm hard-chrome plating to resist wear. The 450 mm stroke is ideal for extending parts across conveyor gaps or pushing loads into machining stations.
This SKU includes a built-in magnet for CMSG, DMSG, or EMSG sensor switches to track rod position. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces. The U flat-end back cover provides a rigid rear mount, and the adjustable cushioning decelerates the piston smoothly near stroke ends to protect end covers on fast moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SU Is Used
PCB Conveyor Transfer
Pushes populated PCB panels across a 450 mm conveyor gap at high speed, using the adjustable air cushion to prevent jarring impacts that could dislodge surface-mount components.
CNC Lathe Bar Loader
Feeds raw bar stock into a CNC lathe collet, relying on the 245 N push force and the built-in magnet for DMSG sensors to confirm full extension before the chuck closes.
Carton Sorting Diverter
Diverts small packaging cartons on a high-speed sorting line, where the double-acting 25 mm bore provides rapid retraction and the U flat-end cover ensures a rigid mount against side deflection.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SU the Right Cylinder?
At 0.5 MPa, this 25 mm bore generates 245 N push and 206 N pull. If you need less force, step down to the 20 mm bore offering 157 N push; if your load is heavier, step up to the 32 mm bore providing 402 N push. Choose this MBLC over the base MBL when cycling fast or moving a heavier mass, as the fixed rubber bumper on the MBL cannot absorb high-impact energy like the tunable air cushion.
With a 450 mm stroke, the 10 mm rod is highly susceptible to bending under side loads. You must use an external linear guide, a pivot bracket, or switch to an MBLD double-rod cylinder to prevent premature seal failure. The cushion needle is screw-adjustable to match your load and speed, but it only decelerates the piston near the ends; it is not a brake and will not hold the rod if air pressure is lost. Replacement match: 25 mm bore, 450 mm stroke, G1/8 port, PT thread, U back cover, magnet included.
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 MBLC25X450SU FAQ
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull. At 0.7 MPa, it delivers 343 N push. The maximum theoretical force is 50 kgf at 1.0 MPa.
The MBLC25X450SU features a screw-tunable needle at both ends that traps a pocket of air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match your specific load and speed, which cuts impact noise and vibration. It only decelerates near the ends and does not lock or hold the rod in place.
