About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SCA
The AirTAC MBLC25X30SCA is a double-acting aluminum mini cylinder engineered for compact actuation. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. The 30 mm stroke is optimal for short, rapid clamping or ejection tasks. Unlike the base MBL, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune end-of-stroke deceleration to protect the end covers on fast moves.
This SKU includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. The riveted rolling-packed aluminum barrel keeps the body light and tight for confined machinery. A built-in magnet (-S) enables position detection with AirTAC CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SCA Is Used
PCB Depaneling Router
Provides 245 N of push force to plunge a high-speed router bit into assembled printed circuit boards, utilizing the adjustable cushion to soften the 30 mm end-of-stroke impact.
Pharmaceutical Vial Sorting
Uses the CA pivot bracket to swing small glass vials into a packaging lane, absorbing angular side-loads while the short 30 mm stroke executes rapid routing.
Semiconductor Test Socket
Applies precise 206 N pull force to extract tested silicon chips from high-frequency test sockets, relying on the -S magnet for DMSG electronic cycle counting.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SCA the Right Cylinder?
The 25 mm bore yields 245 N push force at 0.5 MPa. If your application requires less force, the 20 mm bore offers 157 N; for higher loads, step up to the 32 mm bore providing 402 N. Choose this MBLC over the fixed-bumper MBL when cycling quickly or moving a heavier mass that needs smooth deceleration. Remember that the air cushion only decelerates near the stroke ends; it is not a brake. A plain double-acting cylinder will drift if air is lost, so add an external rod lock for fail-safe position holding.
Exact replacement match: 25 mm bore, 30 mm stroke, G1/8 port, M10x1.25 rod thread, PT port thread, CA pivot back cover, built-in magnet.

- ✓ 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 MBLC25X30SCA FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
The MBLC25X30SCA has a screw-tunable needle at both ends that traps air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match the load and speed, which cuts impact noise and vibration. It only decelerates near the stroke ends and is not a load lock or brake.
