About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125SCA
The AirTAC MBLC25X125SCA is a double-acting aluminum mini cylinder featuring a 25 mm bore and a 125 mm stroke, delivering 245 N of push force at 0.5 MPa. The built-in magnet (-S) enables direct position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. A screw-adjustable pneumatic cushion at both stroke ends decelerates the piston smoothly, which is critical for protecting the end covers on faster or heavier moves where a fixed rubber bumper would fail.
This SKU uses a CA pivot clevis back cover that swings on a pin to accommodate arcing loads, paired with a standard PT tapered port thread. The riveted rolling-packed aluminum barrel keeps the body compact and light for tight spaces, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal ensures consistent friction and longevity across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125SCA Is Used
Textile Loom Guide Arm
Drives a pivoting guide arm on a weaving machine, using the CA clevis to accommodate the natural arc of the mechanism while the cushion absorbs the rapid 125 mm stroke reversals.
Bottling Line Diverter
Actuates a sorting gate on a high-speed beverage line, where the 245 N push force redirects lightweight containers and the magnet confirms gate position for the PLC.
Packaging Flap Folder
Folds cardboard flaps on a carton erector, relying on the adjustable cushion to soften the end-of-stroke impact and prevent crushing the corrugated material.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125SCA the Right Cylinder?
Select this 25 mm bore when an application requires 245 N of push force at 0.5 MPa alongside a pivoting mount. If your move is lighter, stepping down to the 20 mm bore yields 157 N of push force; if you need to move a heavier mass, stepping up to the 32 mm bore provides 402 N. The adjustable air cushion is preferred over the base MBL bumper when cycling rapidly or driving higher inertia, as the needle valve allows you to tune the end-of-stroke deceleration to eliminate impact shock.
This cylinder is double-acting, meaning air both extends and retracts the rod. It does not hold position if air pressure is lost or the valve centers; the rod will drift, so an external rod lock or pilot-operated check valve is required for strict positioning. The replacement match for this unit is a 25 mm bore, 125 mm stroke, G1/8 port, PT thread, CA pivot back cover, with an -S magnet.

- ✓ 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 MBLC25X125SCA FAQ
This 25 mm bore cylinder features a G1/8 port and a Ø10 mm rod. At 0.5 MPa it generates 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.
The MBLC25X125SCA uses a screw-tunable needle valve at both ends to trap and meter exhaust air, decelerating the piston smoothly before it hits the end cover. You adjust it to match the load and speed, which cuts impact noise and vibration. It only decelerates near the ends and is not a brake or load lock.
