About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SU
The AirTAC MBLC25X10SU is a double-acting aluminum mini cylinder with a 25mm bore and 10mm stroke. It generates 245N of push force and 206N of pull force at 0.5 MPa. The built-in magnet (-S) allows position detection using CMSG reed or DMSG and EMSG electronic sensor switches. A U flat-end back cover provides rigid rear mounting.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. This allows you to tune the end-of-stroke deceleration, preventing harsh impacts on fast, short-cycle moves. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the 20 µm hard-chrome plating on the carbon-steel rod resists wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SU Is Used
Electronic Component Testing
Drives a 10mm probe stroke to verify PCB contacts, using the tunable cushion to prevent impact damage on sensitive boards at 245N force.
Semiconductor Pick-and-Place
Actuates a small vacuum gripper for chip placement, relying on the DMSG sensor switch for precise end-position confirmation.
Pharmaceutical Valve Toggling
Pulses a miniature flow diverter in a pill-sorting machine, where the adjustable air cushion silently absorbs the kinetic energy of the rapid 10mm shift.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SU the Right Cylinder?
For a 25mm bore, the neighboring sizes are the 20mm (157N push @0.5MPa) for lighter loads and the 32mm (402N push @0.5MPa) for heavier demands. Choose this MBLC over the standard MBL when your application cycles rapidly and needs smooth deceleration rather than a harsh bumper stop. The cushion only decelerates the piston near the ends; it does not lock the rod or hold position if air pressure is lost. Replacement requires matching the 25mm bore, 10mm stroke, G1/8 port, PT thread, U back cover, and magnet.
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 MBLC25X10SU FAQ
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw needle at each end lets you tune the pneumatic exhaust restriction. This decelerates the piston smoothly over the last few millimeters of travel, reducing noise and end-cover impact on high-frequency moves. It is a damping device, not a load lock or brake.
