About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SCA
The AirTAC MBLC25X10SCA is a compact double-acting aluminum mini cylinder engineered for short 10 mm strokes, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. It features a screw-adjustable pneumatic air cushion at both ends rather than a fixed rubber bumper, allowing you to fine-tune the end-of-stroke deceleration. This protects the end covers from impact wear during rapid cycling, though it functions strictly as a decelerator and not a load lock.
This SKU includes a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, along with a built-in magnet (-S) for position detection. The riveted rolling-packed aluminum barrel keeps the body light and tight for cramped machinery, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist corrosion and scoring. A heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over the cylinder's operating life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SCA Is Used
PCB Component Insertion
Drives a short 10 mm stroke to press connectors onto printed circuit boards, using the adjustable air cushion to soften the 245 N impact and prevent trace damage during high-speed pick-and-place operations.
Packaging Flap Sealing
Pivots via the CA clevis to follow a carton's moving arc, actuating a 10 mm sealing jaw stroke where the magnet confirms jaw position through a DMSG electronic sensor for reliable packaging cycles.
Electronics Test Socket Clamping
Secures delicate microchips in a test fixture with 206 N of pull force, relying on the tunable cushion to decelerate the small 10 mm movement gently before the test probes engage.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10SCA the Right Cylinder?
For applications requiring less force, stepping down to the Ø20 bore provides 157 N of push at 0.5 MPa, whereas moving up to the Ø32 bore yields 402 N if your payload demands more rigidity. Select this MBLC variant over the base MBL when your sequence runs at high speeds or frequencies and the standard fixed bumper cannot adequately absorb the kinetic energy. Remember that a standard double-acting cylinder does not hold position if air pressure drops or the valve centers; the rod will drift, so specify an external pilot-operated check valve if static holding is mandatory.
This replacement unit matches a 25 mm bore, 10 mm stroke, G1/8 port, PT threaded connection, CA pivot back cover, and includes the -S magnet for CMSG, DMSG, or EMSG sensor switches. Because the stroke is very short, side-load stress on the Ø10 mm rod is minimal, but the CA clevis is specifically beneficial if your linkage geometry imposes lateral articulation.

- ✓ 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 MBLC25X10SCA FAQ
This 25 mm bore cylinder uses a G1/8 port and a Ø10 mm rod with an M10x1.25 thread. At 0.5 MPa it generates 245 N push and 206 N pull. At 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The adjustable air cushion at both ends uses a screw needle to meter exhaust flow, decelerating the piston smoothly near stroke ends to reduce impact noise—this is a damping feature, not a braking lock. The CA back cover is a pivot clevis that allows the cylinder to swing on a pin, making it ideal for linkages with angular or arcing motion paths.
