About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X20SCA
The AirTAC MBLC25X20SCA is a compact double-acting aluminum mini cylinder engineered for tight spaces. It produces 245 N of push force and 206 N of pull force at 0.5 MPa. The 20 mm stroke suits short clamping or ejection moves. Unlike the base MBL, this MBLC variant features a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits.
This specific configuration includes a CA pivot back cover that swings on a pin to accommodate arcing loads, preventing rod binding. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for position detection. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø10 mm carbon-steel rod features a 20 µm hard-chrome plating to resist wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X20SCA Is Used
PCB Router Ejection
Uses the 245 N push force and 20 mm stroke to eject cut printed circuit boards from a routing fixture rapidly, relying on the cushion to halt the rod without shock.
Pivot Arm Diverter
Leverages the CA clevis back cover to swing a lightweight diverter arm on a packaging line, accommodating the angular motion during product sorting.
Sensor-Verified Stop
Employs the -S magnet with a DMSG solid-state switch to confirm a 20 mm retraction on a small-parts conveyor stop, ensuring precise timing before release.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X20SCA the Right Cylinder?
For lower force needs, stepping down to the Ø20 bore yields 157 N of push force at 0.5 MPa. If your application requires more power, stepping up to the Ø32 bore provides 402 N. Choose this MBLC over the base MBL when your cycle speeds are high enough that a fixed rubber bumper would cause damaging impact. Remember that the adjustable air cushion only decelerates the rod near the ends; it does not lock or hold position if air pressure is lost. Replacement match: 25 mm bore, 20 mm stroke, G1/8 port, PT thread, CA pivot cover, with magnet.
Quick checklist
- ✓ 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 MBLC25X20SCA FAQ
At 0.5 MPa, it delivers 245 N push and 206 N pull. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends restricts exhaust air to decelerate the piston near the stroke limits. You tune it to match your load and speed, cutting impact and vibration on fast moves. It is a deceleration device, not a load lock.
