About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X115SCA
The AirTAC MBLC25X115SCA is a double-acting aluminum mini cylinder with a 25mm bore and 115mm stroke. It generates 245N of push force and 206N of pull force at 0.5MPa. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke termination, protecting the end covers from impact on faster or heavier moves. The 115mm stroke is well-suited for intermediate linear positioning tasks.
This SKU features a CA pivot/clevis back cover that swings on a pin to accommodate arcing angular loads, preventing rod binding. A built-in magnet (-S) enables position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. The riveted rolling-packed barrel keeps the body compact, while the Ø10mm carbon-steel rod features 20µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal maintains lubrication for a long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X115SCA Is Used
Packaging Flap Folding
Drives intermediate 115mm flap folding arms on case erectors, using the 245N push force to crease cardboard while the air cushion prevents harsh stops during 30-800mm/s cycling.
Textile Guiding Arms
Pivots fabric guiding mechanisms where the CA clevis accommodates the arcing swing of the loom, while the tunable cushion protects thread guides from shock at stroke ends.
Small Part Sorting Diverters
Actuates routing gates on compact conveyor lines, relying on the 206N pull force to retract the diverter and the -S magnet to confirm gate position via a DMSG electronic switch.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X115SCA the Right Cylinder?
If you need less force, the 20mm bore provides 157N push at 0.5MPa; for higher power, step up to the 32mm bore which yields 402N push at 0.5MPa. Select this MBLC version over the base MBL when your application cycles at high frequency or moves a heavier mass, as the tunable air cushion outperforms the fixed rubber bumper of the MBL by allowing you to dial in the exact end-of-stroke deceleration. Remember that the air cushion only decelerates the piston; it does not lock the rod. If you need to hold position without live air, install an external rod lock or pilot-operated check valve. For this 115mm stroke, side-load risk is moderate, but the CA clevis back cover helps absorb angular misalignment. Replacement match: 25mm bore, 115mm stroke, G1/8 port, PT thread, CA back cover, magnet fitted.
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 MBLC25X115SCA FAQ
At 0.5MPa, the cylinder provides 245N of push force and 206N of pull force. At 0.7MPa, the output increases to 343N push and 289N pull. The maximum theoretical force is 50kgf when operated at the 1.0MPa pressure limit.
The CA pivot/clevis back cover allows the cylinder body to swing on a pin, which is essential for arcing loads. The adjustable air cushion at both ends uses a screw needle to trap and exhaust air, decelerating the piston smoothly near the ends. You tune the needle to match your load and speed, which reduces impact noise and vibration without acting as a load lock.
