About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SCA
The AirTAC MBLC25X450SCA is a double-acting, adjustable-air-cushion mini cylinder engineered for compact actuation over a 450 mm travel. It generates 245 N of push force and 206 N of pull force at 0.5 MPa, making it suitable for moving lighter loads across extended distances. The CA pivot back cover allows the body to swing on a pin, accommodating arcing or angular motion paths without binding. A built-in magnet (-S) enables position detection with CMSG, DMSG, or EMSG sensor switches.
Unlike the fixed rubber bumper of the base MBL, this MBLC variant uses a screw-tunable pneumatic cushion at both stroke ends to decelerate the piston smoothly, protecting the end covers during high-frequency or fast cycling. The riveted rolling-packed aluminum barrel keeps the unit lightweight and compact for tight spaces, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion. The heterogeneous two-way grease-retaining piston seal helps maintain consistent lubrication over the 30-800 mm/s operating speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SCA Is Used
Textile Loom Weft Insertion
Drives the guide across a 450 mm path at high frequency; the tunable air cushion prevents sudden end-stop shocks that would snap delicate yarn, while the CA pivot absorbs frame vibration.
Packaging Flap Folder
Folds cardboard flaps on a continuous carton flow, using 245 N of push force at 0.5 MPa; the cushioning ensures the mechanism does not hammer the end covers during rapid 30-800 mm/s cycling.
Warehouse Sorter Diverter
Pivots a sorting arm to redirect small parcels on a conveyor belt; the CA clevis mounting allows the arm to swing naturally, and the -S magnet confirms the extended or retracted position for the PLC.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450SCA the Right Cylinder?
For applications needing less reach or lower force, the neighbouring Ø20 bore provides 157 N of push at 0.5 MPa, whereas stepping up to the Ø32 bore yields 402 N of push force for heavier payloads. Choose this MBLC model over the standard MBL when your cycle speeds are high enough that a fixed rubber bumper would cause damaging end-cover impact. Keep in mind that the adjustable air cushion only decelerates the piston near the ends; it is not a mechanical lock, so the rod will drift if air pressure is lost or the valve centers.
Because this 450 mm stroke is relatively long for a Ø10 mm rod, side-load tolerance is low and the rod is susceptible to bending under lateral forces. To manage this, guide the load externally, rely on the CA pivot bracket to absorb angular misalignment, or consider an MBLD double-rod cylinder for rigid rotational resistance. Replacement parts must match the 25 mm bore, 450 mm stroke, G1/8 port, PT thread, CA clevis cover, and -S magnet configuration.

- ✓ 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 MBLC25X450SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a small amount of exhaust air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match your load and speed, which reduces impact, noise, and vibration on fast cycles. It functions only as an end-of-stroke damper, not a holding brake.
