About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SCA
The AirTAC MBLC25X50SCA is a double-acting aluminum mini cylinder engineered for compact actuation, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. Driven by air on both extend and retract strokes, it uses a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear. The 50 mm stroke is well-suited for short, rapid positioning tasks. Unlike the base MBL series which relies on fixed rubber bumpers, this MBLC variant features a screw-adjustable pneumatic cushion at both ends, allowing you to tune end-of-stroke deceleration to protect the end covers on faster or heavier moves.
This specific SKU includes a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads without binding. The riveted rolling-packed aluminum barrel keeps the overall footprint small and lightweight for tight machine layouts. The built-in magnet (-S) enables contactless position detection when paired with AirTAC CMSG reed switches or DMSG and EMSG solid-state electronic sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SCA Is Used
PCB Depaneling Router
Provides 245 N of push force on a 50 mm stroke to plunge a routing bit, using the adjustable air cushion to prevent sudden impact at the cut's end.
Carton Flap Folder
Swings on its CA pivot to fold packaging flaps at an angle, absorbing side-load variations while the cushioned stroke protects the aluminum end covers.
Chip Test Handler
Actuates a 50 mm clamping probe in semiconductor test fixtures, relying on the -S magnet and DMSG electronic sensors for precise end-of-stroke confirmation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SCA the Right Cylinder?
For sizing flexibility, you can step down to the 20 mm bore if your application requires less force (157 N push at 0.5 MPa), or step up to the 32 mm bore if you need greater thrust (402 N push at 0.5 MPa). Choose this MBLC cushioned model over the standard MBL when your cycle speeds are high or the moved mass is heavy enough that a fixed rubber bumper would cause damaging impact noise. Keep in mind that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake, and a plain double-acting cylinder will not hold position if air pressure is lost or the valve centers. For exact replacement matching, verify the 25 mm bore, 50 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet configuration.

- ✓ 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 MBLC25X50SCA FAQ
At 0.5 MPa, it provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to smoothly decelerate the piston near the stroke limits. You tune it to match the load and speed, reducing impact and noise. It only decelerates near the ends and does not lock or hold the load in place.
