About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50CA
The AirTAC MBLC25X50CA 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. A 50 mm stroke provides a short, direct motion path ideal for tight machinery frames. The defining feature of this MBLC variant is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near the stroke limits to cut impact shock on faster cycles.
This specific SKU features a CA pivot (clevis) back cover, allowing the body to swing on a pin to accommodate arcing or angular loads during travel. It uses a G1/8 port and a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear. Because the barrel is a riveted rolling-packed aluminum tube rather than a rebuildable tie-rod design, the body stays exceptionally light and compact. Note that this model lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50CA Is Used
Textile Loom Guide
Drives a 50 mm yarn guide arm on a weaving loom, using the CA clevis to absorb the slight pivot angle while the cushion prevents end-of-stroke snapping at high frequency.
Pouch Sealing Gate
Actuates a lightweight diverter flap on a packaging conveyor, where the 245 N push force securely moves cardboard flats without crushing them.
PCB Shuttle Pusher
Shifts a populated circuit board shuttle by 50 mm inside an SMT line, relying on the adjustable needle to soften the stop and protect delicate solder joints.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50CA the Right Cylinder?
At a 25 mm bore, this cylinder yields 245 N push and 206 N pull at 0.5 MPa. If your payload is lighter, stepping down to the 20 mm bore reduces the footprint and force to 157 N push. For heavier demands, the 32 mm bore jumps output to 402 N push. Choose this MBLC cushioned version over the base MBL when your cycle speed or moved mass exceeds what a fixed rubber bumper can absorb. Remember that the adjustable air cushion only decelerates motion near the ends; it is not a brake, so a plain double-acting cylinder will drift if air is lost. For replacement, match the 25 mm bore, 50 mm stroke, G1/8 port, PT thread, CA pivot back cover, and no 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 MBLC25X50CA FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, it yields 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
A screw-tunable needle at each end restricts exhaust flow near the stroke limits, decelerating the piston smoothly. You tune the needle to match your load and speed, which protects the end covers from impact—unlike the fixed rubber bumper found on the base MBL series.
