About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300SCA
The AirTAC MBLC25X300SCA is a double-acting aluminum mini cylinder engineered for compact spaces requiring precise end-of-stroke control. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. The 300 mm stroke provides extended travel for moving small parts, while the riveted rolling-packed aluminum barrel keeps the overall footprint tight and lightweight. A heterogeneous two-way grease-retaining piston seal works with the 20 um hard-chrome plated carbon-steel rod to maintain lubrication and extend service life.
This variant features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune the deceleration needle to match your load and speed. This smooths out the transition near stroke ends, cutting impact, noise, and vibration on faster moves—unlike the fixed rubber bumper found on the base MBL. The built-in magnet (-S) supports CMSG reed or DMSG and EMSG electronic sensor switches for position detection, while the CA pivot back cover swings on a pin to accommodate arcing loads.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300SCA Is Used
PCB Shuttle Conveyor
Uses the 300 mm stroke to transfer bare PCBs between inspection stations, relying on the adjustable air cushion to stop the 245 N push force smoothly without jarring delicate solder joints.
Wafer Cassette Loader
Extends to push silicon wafer cassettes into a processing chamber, using the CA pivot back cover to absorb slight angular misalignment on the long 300 mm move.
Pharmaceutical Tray Indexing
Pushes lightweight metal trays into a labeling fixture, where the built-in magnet triggers a DMSG electronic sensor to confirm the 300 mm extension before the labeler fires.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X300SCA the Right Cylinder?
Choose this 25 mm bore when you need 245 N of push force at 0.5 MPa alongside a long 300 mm travel. If your application is lighter, stepping down to the 20 mm bore yields 157 N of push force. For heavier loads, stepping up to the 32 mm bore provides 402 N. The CA pivot mount is specifically designed to handle angular misalignment during the stroke, which is critical at 300 mm since the 10 mm rod has low side-load tolerance and risks bending without proper guidance. You can also pair this with an external guide or an MBLD double-rod cylinder to fully prevent rod deflection.
Select the MBLC over the standard MBL when your cycle speeds or moved masses are high enough that a fixed rubber bumper would cause damaging end-cover impact. Remember that the adjustable air cushion only decelerates the piston near the ends; it is not a lock. If you need to hold position when air is lost or the valve centers, you must add an external rod lock or pilot-operated check valve. This SKU uses a PT port thread and an M10x1.25 rod-end thread.

- ✓ 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 MBLC25X300SCA FAQ
This 25 mm bore cylinder delivers a push force of 245 N and a pull force of 206 N at 0.5 MPa. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. It uses a G1/8 port with PT threading and features an M10x1.25 rod-end thread.
The screw-tunable pneumatic needle at both ends traps a small amount of exhaust air to decelerate the piston smoothly before it hits the end cover. You choose this over the fixed rubber bumper on the base MBL when running faster cycle speeds or moving heavier masses, as it significantly reduces impact noise and vibration. It is strictly a deceleration device and does not lock or hold the load in place.
